Emergency Fund Calculator
Target emergency fund size from monthly expenses and months of coverage.
About the Emergency Fund Calculator
The Emergency Fund Calculator gives you an instant answer from just a few inputs — essential monthly expenses, months of coverage. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
The standard advice of three to six months of expenses is a rule of thumb, not a law — it should flex with how stable your income is and how quickly you could replace it. Freelancers and single-income households with irregular pay generally want the higher end, or more, while dual-income households with stable jobs can lean toward the lower end. The number to multiply is essential spending (housing, food, insurance, minimum debt payments), not your full lifestyle budget, since an emergency fund exists to cover necessities, not to maintain discretionary spending.
How to Use
