Introduction
One of the most common questions we receive from parents at TWINS Education is, “Does IGCSE Economics and Business require strong maths?”
The concern usually arises during Year 9 or Year 10 when students begin choosing their IGCSE subjects. Some schools require students with weaker Mathematics results to move away from the traditional Science stream, leaving them to consider alternatives such as Economics, Business Studies or Accounting. Naturally, parents begin wondering whether these subjects are equally demanding in terms of mathematical ability.
The good news is that the answer is generally no.
Although both IGCSE Economics and Business Studies include calculation questions, neither subject requires advanced Mathematics or Additional Mathematics. Most calculations involve basic arithmetic, percentages, ratios and the application of simple formulas that are provided throughout the syllabus. Students who have a reasonable foundation in lower secondary Mathematics are usually able to cope with these calculations after sufficient classroom practice.
However, there is an important point that many students and parents overlook. Many families also assume IGCSE Economics is tough simply because it contains graphs and calculations, but the challenge is often very different from what they expect.
Scoring well in these subjects is often not about completing the calculation. Instead, students are expected to interpret the figures, explain their significance and apply them to real business or economic situations. In many examination questions, the explanation after the calculation carries more marks than the calculation itself.
At TWINS Education, we have taught IGCSE Economics tuition and Business Studies to students from a wide range of academic backgrounds since 2014. Over the years, we have seen many students who were initially worried about their Mathematics eventually achieve excellent IGCSE results after learning the correct exam techniques and understanding how to interpret data effectively.
In this article, we will explain the level of Maths required in both subjects, compare the types of calculations students can expect, and help parents decide whether IGCSE Economics or Business Studies is a suitable choice for students who are not particularly strong in Mathematics.
The Short Answer: Strong Maths Is Not Required for Either Subject
If you are looking for a direct answer to the question, does IGCSE Economics and Business require strong maths?, the answer is no.
Neither subject expects students to solve complex algebraic equations, perform calculus, or apply advanced mathematical concepts. Instead, students mainly use everyday mathematical skills that they have already learnt during lower secondary school.
Some examples include:
- Calculating percentages
- Working out simple ratios
- Adding, subtracting, multiplying and dividing numbers
- Reading tables, graphs and charts
- Applying straightforward formulas given in the syllabus
For most students, the calculations themselves are not particularly difficult. In fact, many can be completed using just a few simple steps.
Where students often struggle is what comes after the calculation.
For example, after calculating a firm’s gross profit margin or a product’s price elasticity of demand, the examination question may ask students to explain what the result means, discuss its impact on the business or economy, or evaluate whether the figure is considered favourable. These higher-order thinking skills are where most examination marks are awarded.
This is why students with average Mathematics ability can still achieve an A or A* in IGCSE Economics or an A or A* in IGCSE Business Studies. As long as they understand the concepts, know how to apply the formulas correctly and develop strong analytical and evaluation skills, they are fully capable of performing well in the examination.
Parents should also note that although Business Studies generally contains more calculation topics than Economics, both subjects place a much greater emphasis on understanding, application and written explanation than on mathematical complexity. In other words, students are assessed more on how they think than on how quickly they calculate.
For this reason, students should not rule out either subject simply because they are not among the strongest Mathematics students in their class. With the right guidance, consistent practice and effective exam strategies, many students find that both IGCSE Economics and Business Studies are far more manageable than they initially expected.
What Maths Is Used in IGCSE Economics?
When parents ask, does IGCSE Economics and Business require strong maths, many assume that Economics will involve a significant amount of mathematical calculation. This is understandable because Economics contains graphs, formulas and numerical data. However, the reality is that IGCSE Economics does not require advanced mathematical ability.
The calculations in IGCSE Economics are usually based on basic mathematical concepts that students have already encountered before entering upper secondary school. Students are not expected to perform complicated calculations. Instead, they need to understand the economic concept behind each calculation and know how to interpret the result.
Some common areas where Maths is used in IGCSE Economics include:
1. Percentage Changes
Percentage calculations are one of the most common mathematical skills required in Economics.
Students may need to calculate changes in:
- Price
- Quantity demanded
- Quantity supplied
- National income
- Inflation rate
- Unemployment rate
For example, if the unemployment rate increases from 5% to 7%, students should be able to calculate the percentage point change and explain the possible economic impact.
The calculation itself is straightforward. The challenging part is explaining what the increase means.
A strong answer does not simply state:
“Unemployment increased by 2%.”
Instead, students need to explain:
“An increase in unemployment means more people are unable to find jobs. This may reduce household income, lower consumer spending and negatively affect economic growth.”
This shows that Economics is not just about numbers. It is about understanding the relationship between figures and real-world outcomes.
2. Price Elasticity of Demand (PED) and Price Elasticity of Supply (PES)
PED and PES are among the most well-known calculations in IGCSE Economics.
Students use formulas such as:
While the formulas may appear intimidating initially, the mathematical process only requires students to calculate percentage changes and perform division.
The more difficult part is interpreting the final answer. In fact, many students lose marks because of the common mistakes when it comes to IGCSE Economics, even when they calculate the formula correctly.
For example, if a product has a PED value greater than 1, students need to understand that demand is price elastic. This means consumers are relatively responsive to changes in price. A business may need to consider this information when deciding whether to increase or decrease prices.
Therefore, even though there is a formula involved, exam success depends more on economic reasoning than mathematical ability.
3. Interpreting Graphs and Data
Another area where students use numerical skills is analysing economic diagrams, tables and data.
Students may need to interpret information related to:
- Demand and supply changes
- Inflation trends
- Economic growth
- Exchange rates
- Government policies
However, they are not expected to analyse complicated statistical models. They mainly need to identify trends, compare figures and explain possible causes and consequences.
For example, if a graph shows inflation increasing from 2% to 6%, students need to explain how this may affect consumers, businesses and the overall economy.
The ability to explain the economic impact is usually more important than the ability to read the numbers.
What Maths Is Used in IGCSE Business Studies?
Compared with Economics, IGCSE Business Studies generally involves more calculations. This is because students are often required to analyse business performance using financial information.
However, this does not mean students need strong Maths.
The calculations used in IGCSE Business Studies are mainly formula-based. Once students understand the formula and practise applying it, the process becomes systematic.
At TWINS Education, we often remind students in our Business Studies IGCSE tutorial class that calculations are not difficult because of the mathematics involved. The challenge is knowing which calculation to use, what the result means, and how to relate it back to the business situation given in the question. This is also why students should be aware of the common mistakes in IGCSE Business that can cause them to lose marks even when they understand the basic concepts.
Some common calculation areas include:
Some common calculation areas include:
1. Costs, Revenue and Profit Calculations
Students need to understand basic business calculations such as:
These concepts are fundamental because businesses need to understand whether their operations are financially successful.
For example, a company may have high revenue but low profit because its costs are too high. A student who only calculates the figures without explaining the business implication will lose marks.
A higher-scoring answer would explain:
“The business has increased revenue, but the increase in variable costs has reduced profit margins. Therefore, the company should consider ways to control costs to improve profitability.”
Again, the calculation is only the first step.
2. Break-Even Analysis
Break-even analysis is another area that students commonly encounter in IGCSE Business Studies.
Students may need to calculate:
They may also need to interpret a break-even chart and explain:
- The level of output required before making a profit
- The margin of safety
- The risks faced by the business
- The impact of changes in costs or selling prices
Many students initially worry when they see break-even charts because they contain graphs and formulas. However, after practising several examples, most students find the calculations quite manageable.
The more important skill is understanding what the break-even point tells the business owner.
For example:
“A lower break-even point means the business needs to sell fewer units before making a profit. This reduces business risk because the company can recover its costs more quickly.”
This type of explanation demonstrates application and analysis, which are highly valued in the IGCSE Business Studies marking scheme.
Students who want to improve further should also learn how to approach questions effectively and focus on earning evaluation marks in IGCSE Business, as these higher-level skills often separate average answers from top-scoring responses.
3. Profitability Ratios
IGCSE Business Studies also introduces students to financial ratios that help evaluate business performance.
Examples include:
Gross Profit Margin
Return on Capital Employed (ROCE)
These calculations help students assess whether a business is using its resources effectively.
For example, if ROCE increases from 10% to 15%, students should not stop after calculating the percentage. They should explain that the business is generating a higher return from the capital invested.
4. Liquidity Ratios
Students may also learn calculations related to a business’s ability to pay short-term debts.
Examples include:
Current Ratio
Liquid Ratio (Quick Ratio)
These calculations require only basic division. However, students need to understand what the ratio indicates.
A low liquidity ratio may suggest that a business could face difficulty paying short-term obligations, while an excessively high ratio may indicate that the company is not using its assets efficiently.
Overall, when comparing the two subjects, IGCSE Business Studies contains more calculation topics than IGCSE Economics. However, neither subject requires strong mathematical ability.
The key difference is that Business Studies calculations are often linked directly to business decision-making, while Economics calculations are usually used to analyse economic relationships and trends.
However, having some Economics knowledge for IGCSE Business exam can also help students better understand topics such as market conditions, demand, supply and external factors affecting businesses.
For both subjects, students who can calculate accurately and explain the meaning behind the figures will have a significant advantage in examinations.
Why Interpretation Is More Important Than Difficult Calculations
When discussing does IGCSE Economics and Business require strong maths, many parents focus on whether their child can perform the calculations. However, based on our experience teaching IGCSE students, the bigger challenge is usually not the calculation itself. It is the ability to interpret the figures and explain what they mean.
This is one of the biggest differences between Mathematics and subjects like Economics and Business Studies.
In Mathematics, students are often assessed on whether they can obtain the correct answer by applying the correct method. In Economics and Business Studies, obtaining the correct answer is only the first step. Students must then demonstrate that they understand the significance of that answer in a real-world context.
For example, imagine a Business Studies question asking students to calculate a company’s profit margin.
A student may correctly calculate that the profit margin has decreased from 20% to 12%. However, this alone may only earn limited marks.
A stronger answer would continue by explaining:
“The decrease in profit margin suggests that the business is earning less profit from each dollar of revenue generated. This could be caused by rising costs or reduced selling prices. As a result, the business may need to review its pricing strategy or implement cost-control measures.”
The difference between these two answers is not mathematical ability. It is analysis and evaluation.
Looking at IGCSE Business sample answers that score Band 3 can help students understand the difference between a basic response and an answer that demonstrates strong application, analysis and evaluation skills.
At TWINS Education, we often observe that students who initially describe themselves as “weak in Maths” can perform well in Economics and Business Studies once they understand how to approach examination questions. The main improvement usually comes from learning how to:
- Identify what the numbers are showing
- Link calculations to business or economic concepts
- Explain causes and consequences
- Make justified recommendations
This is why parents should not judge a student’s suitability for Economics or Business Studies based solely on their Mathematics grade.
A student who obtains a B or C in Mathematics but has strong logical thinking and enjoys understanding how businesses and economies work may actually perform better than a student with excellent mathematical ability but weak explanation skills.
Should Students Who Are Weak in Maths Choose IGCSE Economics or Business Studies?
For students who are not strong in Mathematics, both IGCSE Economics and Business Studies can still be suitable subject choices.
However, parents should consider several factors beyond mathematical ability.
1. Interest in Real-World Issues
Economics is suitable for students who enjoy understanding questions such as:
- Why do prices increase?
- Why does unemployment happen?
- How do government policies affect people and businesses?
- Why do exchange rates change?
Students who enjoy reading about current affairs, society and global issues often find Economics more engaging.
Business Studies may appeal more to students who are interested in:
- How companies operate
- Entrepreneurship
- Marketing strategies
- Business decisions
- Financial performance
Students who enjoy these areas may also find that IGCSE Business helps in A-level or University course selection by building useful foundations in areas such as business management, finance, accounting and entrepreneurship.
Interest plays a major role because both subjects require students to understand concepts and apply them to different scenarios.
2. Ability to Explain and Analyse
Both subjects require students to write structured answers.
A common misconception is that students who are weak in Mathematics will automatically find Economics or Business Studies easier because they are “less mathematical”. This is not always true.
While the calculations are manageable, students still need to develop:
- Clear written communication
- Logical reasoning
- Ability to analyse information
- Ability to evaluate different viewpoints
For example, a Business Studies question may ask:
“Evaluate whether a business should reduce prices to increase sales.”
There is no difficult calculation involved. However, students need to consider both advantages and disadvantages before making a justified recommendation.
Similarly, an Economics question may ask:
“Discuss whether reducing interest rates is the best way to increase economic growth.”
Students must analyse the possible benefits and limitations of the policy.
Therefore, students who are comfortable expressing ideas and explaining their reasoning often have an advantage.
3. Do Students Need Add Maths for IGCSE Economics or Business Studies?
Another common question from parents is whether students need to take Additional Mathematics to study Economics or Business Studies. Parents also frequently ask whether taking extra subjects such as IGCSE Economics is worthwhile for students who already have a full academic timetable.
The answer is generally no.
Additional Mathematics is not a requirement for either IGCSE Economics or Business Studies. The calculations involved in both subjects are based mainly on basic mathematical skills rather than advanced concepts.
Students who take Additional Mathematics may find certain numerical concepts easier, but it is not necessary for achieving a strong grade.
At TWINS Education, we have taught students from different academic backgrounds, including those who did not take Additional Mathematics, and many have successfully achieved strong IGCSE results in Economics and Business Studies.
The important factor is not whether students take the most advanced Mathematics subject. It is whether they build a strong understanding of concepts, practise examination techniques and learn how to apply knowledge effectively.
Final Advice for Parents
If your child is considering IGCSE Economics or Business Studies but is worried about Mathematics, do not immediately eliminate these subjects based on their Maths ability alone.
The better questions to ask are:
- Does my child enjoy understanding how businesses and economies work?
- Can my child explain ideas clearly?
- Is my child willing to practise and improve?
- Can my child apply concepts to real-life situations?
If the answer is yes, then your child can still succeed in these subjects.
Ultimately, does IGCSE Economics and Business require strong maths? The answer is no. Both subjects require students to use numbers, but they do not require advanced mathematical ability. Success depends much more on understanding concepts, interpreting information and applying knowledge effectively.
Conclusion
Choosing IGCSE subjects is an important decision, and many parents worry that students who are weaker in Mathematics may struggle with Economics or Business Studies. However, the reality is that does IGCSE Economics and Business require strong maths? The answer is no.
Both subjects require students to use basic mathematical skills, including percentages, ratios and simple formulas. IGCSE Economics includes calculations such as PED, PES and percentage changes, while IGCSE Business Studies involves more calculation-based topics such as costs, revenue, break-even analysis, profitability ratios and liquidity ratios.
However, these calculations are only one part of the subject. The ability to interpret figures, analyse information and explain the impact of decisions is often more important than the calculation itself.
From our experience at TWINS Education, many students who initially lack confidence in Mathematics are still able to perform well in IGCSE Economics and Business Studies when they receive proper guidance and learn the correct examination techniques.
Therefore, students should not avoid these subjects simply because they are not top Mathematics students. It is also helpful for parents to understand the role of IGCSE Economics in college and university admission when choosing subjects that support their child’s future academic goals.
With the right preparation and support, students with average mathematical ability can still achieve excellent results in both IGCSE Economics and Business Studies.
