Formulas decide many marks in the CFA Level 1 exam. A smart CFA Level 1 formula sheet saves hours during revision. This guide lists the important formulas and concepts for the 2026-27 cycle. Use it as your final revision companion for every topic.
Many candidates memorise the CFA Level 1 formula sheet without understanding them. That approach fails on application questions. Therefore, this blog explains when to use each formula and why it works. Each section follows a logical topic flow, so you can revise in a clean sequence.
Why Do Formulas Matter in the CFA Level 1 Exam?
The CFA Level 1 exam tests 180 multiple-choice questions in 4.5 hours. Many questions need quick calculations. A missed formula costs both time and marks. Early review of the CFA Level 1 exam pattern improves your formula practice. Speed matters as much as accuracy.
Formulas also anchor concepts. A ratio or valuation model shows how variables interact. When you know the formula, you predict the effect of each input. Examiners often hide the CFA Level 1 formula sheet inside a short case. Recognising it quickly gives you a clear edge. Consequently, conceptual questions become far easier to solve.
Weightage also guides your revision. Ethics carries 10 to 15 percent in the 2027 curriculum. Quantitative Methods carries 11 to 14 percent. Derivatives and Alternative Investments each carry 6 to 9 percent. Therefore, spend more formula time on calculation-heavy topics.
How Should You Use a CFA Level 1 Formula Sheet?
Treat the CFA Level 1 formula sheet as a revision tool, not a first-read resource. Study each concept from the CFA Level 1 syllabus first. Then use the sheet to test recall. Write each formula from memory, and check your answer against the sheet. This active method builds lasting recall.
Keep your CFA Level 1 formula sheet short. Limit it to four pages in total. Include each formula, its variables and one worked example. Long sheets defeat the purpose of quick revision. Brevity forces you to prioritise high-yield formulas. Use a one-line note for each common trap.
Practise formulas on the approved calculator too. CFA Institute permits the Texas Instruments BA II Plus and the HP 12C. Learn the time value of money keys, cash flow worksheet and statistics mode. These shortcuts save valuable time on quantitative questions.
Which Quantitative Methods Formulas Should You Revise?
Start with the time value of money. Future value equals PV × (1 + r)^N. Present value equals FV ÷ (1 + r)^N. Effective annual rate equals (1 + periodic rate)^m − 1. Many other topics build on these three formulas.
Next, review return measures. Holding period return equals (ending value − beginning value + income) ÷ beginning value. Net present value sums discounted cash flows minus the initial outlay. Internal rate of return sets that net present value to zero. Accept projects when NPV is positive.
Statistics formulas come next. Sample mean equals the sum of observations divided by n. Variance averages squared deviations from the mean. Standard deviation is its square root. Z-score equals (x − mean) ÷ standard deviation. Correlation equals covariance ÷ (σx × σy). Sample variance divides by n − 1.
Probability and hypothesis testing follow. Bayes’ theorem updates a prior probability with new evidence. The t-statistic equals (sample mean − hypothesised mean) ÷ standard error. Reject the null hypothesis when the test statistic exceeds the critical value. Remember, Type I error means rejecting a true null.
The 2027 curriculum also adds artificial intelligence topics to Quantitative Methods. Expect conceptual questions on how models learn and where they fail. Simple regression still matters. The slope equals covariance divided by the variance of X. The intercept equals mean Y minus slope times mean X.
CFA Level 1 Formula Sheet: Which Economics Formulas Are Important?
Economics formulas stay simple but tricky. Price elasticity equals percentage change in quantity ÷ percentage change in price. Income elasticity uses income instead of price. GDP by the expenditure approach equals C + I + G + (X − M).
Currency questions appear often. The forward rate equals spot × (1 + domestic rate) ÷ (1 + foreign rate). Quote rates as domestic currency per foreign currency. Also recall the Fisher effect: nominal rate roughly equals real rate plus expected inflation.
Which Financial Statement Analysis Formulas Should You Know?
Start with liquidity ratios. Current ratio equals current assets ÷ current liabilities. Quick ratio excludes inventory from current assets. Then check solvency. Debt-to-equity equals total debt ÷ total equity. Interest coverage equals EBIT ÷ interest expense. Strong ratios signal financial stability.
Profitability and efficiency ratios matter next. Net profit margin equals net income ÷ revenue. Return on equity equals net income ÷ average equity. Inventory turnover equals COGS ÷ average inventory. Days sales outstanding equals 365 ÷ receivables turnover. Practise computing each ratio from a sample balance sheet.
The DuPont analysis splits return on equity into three drivers. ROE equals net profit margin × asset turnover × equity multiplier. This breakdown reveals whether margins, efficiency or leverage drives returns. Examiners test this formula often, so practise both three-step and five-step versions.
Depreciation and cash flow formulas need equal care. Straight-line depreciation equals (cost − salvage value) ÷ useful life. Double-declining balance uses 2 ÷ useful life times book value. FCFF equals CFO + interest × (1 − t) − capital expenditure.
What Corporate Issuers and Equity Formulas Matter?
Cost of capital drives many corporate finance questions. WACC equals wd × rd × (1 − t) + we × re. Here, wd and we are the weights of debt and equity. CAPM sets cost of equity at rf + β × (Rm − rf).
Equity valuation relies on a few core models. The Gordon growth model gives value as D1 ÷ (r − g). Price-to-earnings equals price per share ÷ earnings per share. Sustainable growth equals retention ratio × ROE. Match each model to the company’s growth profile.
Dividend questions often test the payout ratio. Dividend payout equals dividends ÷ net income, and the retention ratio equals 1 minus payout. Share buybacks and dividends both return cash. However, buybacks give shareholders flexibility on timing and taxes. Read each question carefully to spot which distribution method applies.
Which Fixed Income Formulas Should You Revise?
Bond pricing forms the base of fixed income. Price equals the present value of coupons plus the present value of par. Current yield equals annual coupon ÷ price. Yield to maturity is the discount rate that equates price and cash flows. Prices and yields move in opposite directions.
Duration measures interest rate risk. Modified duration equals Macaulay duration ÷ (1 + yield per period). The price change approximates −modified duration × change in yield. Convexity refines this estimate for large yield moves. Adding the convexity term makes the approximation more accurate.
Spot rates and forward rates also appear regularly. Discount each cash flow at its own spot rate. Forward rates follow from (1 + z2)² = (1 + z1) × (1 + f). Practise these calculations on your calculator to build speed.
Credit and yield spread concepts also deserve attention. Yield spread equals bond yield minus benchmark yield. A wider spread signals higher credit risk. Bonds with longer maturity usually carry larger spreads. Learn these relationships qualitatively, because they appear in concept-based questions.
Which Derivatives and Portfolio Management Formulas Are Essential?
Derivatives pricing rests on no-arbitrage logic. A forward price with no income equals spot × (1 + r)^T. Put-call parity says c + X ÷ (1 + r)^T = p + S. Violations create arbitrage profits. Check parity first when a question involves options.
Portfolio management builds on risk and return. Expected portfolio return equals the weighted average of asset returns. For two assets, variance equals w1²σ1² + w2²σ2² + 2w1w2ρσ1σ2. Lower correlation reduces portfolio risk. Diversification therefore works best when assets move differently.
Risk-adjusted return ratios complete the picture. Sharpe ratio equals (portfolio return − risk-free rate) ÷ standard deviation. Treynor ratio replaces standard deviation with beta. Jensen’s alpha equals actual return minus CAPM expected return. Higher values indicate better compensation for the risk taken.
Ethics needs concepts, not formulas. Memorise the seven Standards of Professional Conduct and the GIPS principles. Practise case-based questions to apply each Standard. Ethics questions test judgment rather than arithmetic. Alternative Investments need fee calculations and net asset value logic. Review those formulas briefly.
How Can You Memorise the CFA Level 1 Formula Sheet Faster?
Understand each formula before you memorise it. Derive it from first principles where possible. For example, see how present value comes from discounting future cash flows. Understanding builds recall that survives exam pressure, while rote learning fades within days. Try this habit with every topic.
Use spaced repetition with flashcards. Write the formula on one side and the use case on the other. Review cards daily for ten minutes. Additionally, group formulas by topic so your brain links related ideas. Short daily sessions beat long weekend marathons.
Check accuracy through timed drills. Solve five calculation questions in ten minutes every day. Track errors in a notebook and revisit them weekly. Over time, your speed improves and careless mistakes drop. This habit pays off during the actual exam.
Structured guidance speeds up this process. The CFA Level 1 online course on ixambee follows a clear learning path. You can revise concepts and formulas in a fixed order. Consequently, you avoid random studying and cover the syllabus confidently. Steady structure keeps your revision on track.
What Is the Best Revision Plan for the 2026-27 Cycle?
Pick your exam window first. February 2027 runs from 22 to 28 February. May 2027 runs from 11 to 17 May. Check the latest CFA Level 1 exam dates before fixing your study calendar. Then work backwards from your chosen date.
Divide your final twelve weeks into three phases. Spend weeks one to six on concept revision with your formula sheet. Use weeks seven to ten for topic-wise practice questions. Reserve the last two weeks for full-length tests and quick formula recall. This rhythm keeps stress low.
Late starters can use the CFA Level 1 crash course for focused revision. Then test yourself with CFA Level 1 mock tests. Each attempt shows which formulas you forget under pressure. Add those formulas to your daily flashcard review. Repeat this cycle weekly.
What Should You Do Next?
Build your own one-page formula sheet today. Copy the formulas above by hand, and add notes on common traps. Update the sheet after every mock test. A personal sheet works better than any borrowed one because you understand every line.
