AP Macroeconomics cheat sheet the graphs, formulas, and a cram chart.

This AP Macroeconomics cheat sheet — also called an AP Macro cheat sheet — puts the models that actually win points on one page: the must-know graphs, the key formulas, and a unit-by-unit cram chart. Use it as fast review in your final week.

What an AP Macro cheat sheet is (and what you can’t bring)

A cheat sheet here means a condensed, high-yield study tool, not something you carry into the exam. AP Macroeconomics gives you no formula sheet and you cannot bring your own notes — you may use a basic four-function calculator, but the relationships and graphs come from you. Think of this page as what you review the night before.

What makes a macro cram chart so useful is that the whole course really is a small set of graphs and formulas applied over and over. Lock those in and most questions become the same few moves.

The must-know graphs

Most AP Macro questions are a version of “shift this curve and explain what happens.” These are the models to know cold.

Aggregate demand & supply (AD–AS)

Sets real GDP and the price level; the core model for fiscal and monetary policy and output gaps.

Money market

Money supply (vertical) and money demand set the nominal interest rate; shifts drive monetary policy.

Loanable funds market

Supply of and demand for loans set the real interest rate; used for crowding out and saving-investment.

Phillips curve

The short-run trade-off between inflation and unemployment, plus the vertical long-run curve.

Foreign exchange (forex)

Supply and demand for a currency set its exchange rate; used for trade and capital flows.

Production possibilities curve

Shows scarcity, opportunity cost, and economic growth.

The key formulas

GDP = C + I + G + Xn

The expenditure approach to gross domestic product.

Spending multiplier = 1 / (1 − MPC) = 1 / MPS

How an initial change in spending ripples through the economy.

MPC + MPS = 1

Marginal propensity to consume plus to save.

Money multiplier = 1 / reserve ratio

The maximum change in the money supply from a new deposit.

Real interest rate = nominal rate − inflation

The Fisher relationship.

Real GDP = (nominal GDP / GDP deflator) × 100

Adjusting output for changes in the price level.

The unit-by-unit cram chart

Six units, each boiled down to the idea, the must-know tool, and the trap to dodge.

Unit 1 — Basic concepts

Idea: scarcity forces trade-offs. Must-know: opportunity cost, the PPC, and comparative advantage. Watch out: confusing absolute with comparative advantage.

Unit 2 — Indicators & the business cycle

Idea: measure the economy’s health. Must-know: GDP, the three types of unemployment, and CPI inflation. Watch out: mixing up nominal and real values.

Unit 3 — National income & prices

Idea: AD and AS set output and prices. Must-know: the multiplier and fiscal policy shifts. Watch out: shifting the wrong curve, or the wrong direction. (heavily tested)

Unit 4 — Financial sector

Idea: money markets set interest rates. Must-know: the money market, the money multiplier, and the Fed’s tools. Watch out: confusing the money market with loanable funds. (heavily tested)

Unit 5 — Long-run policy

Idea: policy has long-run trade-offs. Must-know: the Phillips curve, crowding out, and long-run growth. Watch out: mixing up the short-run and long-run Phillips curves. (the heaviest unit)

Unit 6 — Open economy

Idea: economies trade and exchange currency. Must-know: the balance of payments and the forex market. Watch out: getting the direction of a currency appreciation backwards.

Where students lose the most points

On AP Macro, most lost points are on the graphs and the explanation, not the arithmetic. Free-response graders want a correctly drawn, fully labeled graph and a sentence explaining the economic cause and effect, so an unlabeled axis or a missing shift arrow costs points even with the right idea. Draw big, label everything, and say why it moves. Our FRQ guide shows exactly where the rubric points live.

Frequently asked questions

Quick answers — written by humans, not a chatbot.

Can I bring a cheat sheet into the AP Macroeconomics exam?

No. AP Macro provides no formula sheet and you cannot bring notes, though a basic four-function calculator is allowed. A cheat sheet is for review beforehand.

What graphs do I need to know for AP Macro?

The AD–AS model, the money market, loanable funds, the Phillips curve, foreign exchange, and the production possibilities curve.

What is the best way to cram for AP Macroeconomics?

Master the graphs and formulas first, then practice drawing labeled graphs on past free-response questions under a timer.

Which AP Macro units are most important?

National income (Unit 3), the financial sector (Unit 4), and long-run policy (Unit 5) carry the most weight — together most of the exam.

Is AP Macroeconomics hard?

It is one of the more challenging AP exams because it is abstract and graph-heavy. Our difficulty guide gives an honest breakdown.
