The IB Economics Higher Level (HL) course relies heavily on a student's ability to master mathematical calculations, especially for Paper 3, which is almost entirely calculation-based. Unlike other IB subjects, there is no official "data booklet" provided during the exam, meaning all formulas must be memorized.
The following "repack" organizes the essential formulas and concepts you need to master for the current syllabus. 1. Fundamentals & Microeconomics
Microeconomics calculations focus on market behavior, consumer choices, and firm performance. Linear Functions: Demand: is the intercept and is the slope). Supply: is the intercept and is the slope).

is a synthesized, highly structured revision guide designed to help Higher Level students rapidly access and apply quantitative economic tools. While the International Baccalaureate (IB) does not provide an official standalone formula booklet for Economics in the same way it does for Mathematics, students must master a specific set of mathematical formulas to achieve a top grade of 7 on Paper 3 (the quantitative paper) and Paper 1 & 2 data response questions.
This report breaks down the essential formulas required for the IB Economics HL syllabus, categorized by core units, to serve as a comprehensive "repack" for examination preparation. 📊 Core Quantitative Syllabus Breakdown 1. Microeconomics (Unit 2)
Microeconomics contains the highest concentration of mathematical calculations in the syllabus, focusing heavily on elasticities and firm theory. Elasticities Price Elasticity of Demand (PED): Cross Price Elasticity of Demand (XED): Income Elasticity of Demand (YED): Price Elasticity of Supply (PES): Costs, Revenues, and Profits Total Revenue (TR): Average Revenue (AR): Marginal Revenue (MR): Total Cost (TC): (Total Fixed Cost + Total Variable Cost) Average Total Cost (ATC): Marginal Cost (MC): Economic Profit: (where TC includes both explicit and implicit costs) Government Intervention
Consumer Surplus: Area above the price and below the demand curve: The IB Economics Higher Level (HL) course relies
Producer Surplus: Area below the price and above the supply curve: Social/Community Surplus: 2. Macroeconomics (Unit 3)
Macroeconomic calculations focus on measuring economic activity, inflation, and the multiplier effect. Measuring National Income GDP (Expenditure Approach): GNI (Gross National Income): Real GDP: Inflation and Employment Inflation Rate: Unemployment Rate: The Keynesian Multiplier Marginal Propensity to Consume (MPC): Keynesian Multiplier ( ): 3. The Global Economy (Unit 4)
Calculations in global economics revolve around currency exchange, terms of trade, and protectionist measures. Trade and Exchange Rates Terms of Trade (ToT):
Linear Exchange Rates: Setting demand for currency equal to supply (e.g., ) to solve for the equilibrium exchange rate. 📈 Analysis of Pedagogical Value
The "Repack" of these formulas provides several distinct advantages for high-stakes IB preparation:
Paper 3 Mastery: Paper 3 is strictly quantitative. Having these formulas memorized and internalized is the difference between a grade 5 and a grade 7.
Time Efficiency: Synthesis reduces the bloat of standard textbook chapters into raw, actionable mathematical operations. Cross-Unit Application: Formulas like percentage change (
) apply universally across demand, inflation, and economic growth tracking.
IB Economics HL Formula Booklet Repack is a streamlined, student-optimized version of the official IBO data booklet, specifically designed to bridge the gap between abstract formulas and exam-day application. While the official booklet provides the raw math, a "repack" reorganizes these tools into a logical workflow for Paper 2 and Paper 3. 1. The Core Purpose
The repack isn't just a list; it’s a strategy guide. It focuses on the Quantitative Methods
required for Higher Level (HL) students, ensuring that you don't just see a formula, but understand the economic relationship it describes. It typically categorizes formulas by the four main units: Introduction to Economics, Microeconomics, Macroeconomics, and The Global Economy. 2. Key Sections Included
A high-quality repack generally organizes content into three pillars: Microeconomics (Unit 2): Covers elasticities ( cap P cap E cap D cap X cap E cap D cap Y cap E cap D cap P cap E cap S
), utility theory, and the complex cost theory calculations (Marginal Cost, Average Total Cost, and Profit Maximization where Macroeconomics (Unit 3):
Focuses on the Keynesian multiplier, GDP/GNP calculations (expenditure, income, and output approaches), and inflation measurements using CPI. The Global Economy (Unit 4):
Includes comparative advantage calculations, terms of trade, and exchange rate conversions. 3. Why Use a Repack Over the Official Booklet? Contextual Cues: Many repacks include brief "condition" notes (e.g., "If
, demand is elastic") which the official IBO version excludes. Visual Mapping:
They often include standard diagrams that correspond to the formulas, helping you visualize the "Area of Consumer Surplus" or "Deadweight Loss" alongside the math. Step-by-Step Layout:
For complex multi-step problems—like calculating the effects of a subsidy or tariff—a repack lists formulas in the order you would actually use them during a Paper 3 calculation. 4. Strategic Advice for HL Students Memorize the "Why," Use the "How":
The formula booklet is a safety net, but speed is vital in Paper 3. Use the repack to build muscle memory so you aren't searching for the Multiplier formula ( ) while the clock is ticking. Units Matter:
Always pair your formulas with the correct units (e.g., percentages for elasticity, currency symbols for GDP). The 1% Rule:
In IB Economics, the math is rarely "hard" calculus; it is simple arithmetic applied to complex concepts. The repack helps you stay focused on the concept rather than getting lost in the numbers.

Macro formulas are the most dangerous because they are easy to confuse. Your repack must separate the Keynesian from the Monetarist formulas.
Advanced HL Addition: In your repack, add a specific line for the Equilibrium level of income (Y) involving the 45-degree line: Y = C + I + G + (X – M). Then expand C to a + bYd (where a = autonomous consumption, b = MPC, Yd = disposable income).
The official booklet scatters the expenditure approach (GDP = C+I+G+(X-M)), the multiplier, and the Phillips curve. A repack forces them onto a single spread.
The official IB Formula Booklet is mathematically correct but pedagogically sparse. It presents the "What" (the formula) without the "How" or "Why."
