Emergency Fund Calculator

An emergency fund is your financial safety net — enough cash to cover the essentials if your income stops. This works out how big yours should be, how much you still need, and how long it'll take to get there at your current savings rate. Updates as you type.

Building your safety net

Your target is simply your essential monthly costs times the months of cover you want:

target = monthly essentials × months of coverage

months to goal = (target − already saved) ÷ saved per month

• Start with one month, then build. Even a small buffer stops a surprise bill becoming debt.
• Only count essentials — the things you must pay if income stops. Don't pad it with discretionary spending.
• Keep it accessible and safe — a separate high-yield savings account, not investments.

This is an educational estimate. Your right number depends on your job security and dependents. Not financial advice.

FAQ

How much should an emergency fund be?

A common guideline is 3 to 6 months of essential living expenses — rent or mortgage, food, utilities, insurance, minimum debt payments and transport. Choose 3 months if you have very stable income and few dependents, and 6 months or more if your income is variable (freelance, commission) or you support a family. This calculator multiplies your monthly essentials by the number of months you pick.

What counts as an essential expense?

Only the things you would still have to pay if your income stopped: housing, food, utilities, insurance, transport, and minimum loan or credit-card payments. Leave out discretionary spending like dining out, subscriptions and holidays — in a real emergency you would cut those, so they should not inflate your target.

How long will it take to build my emergency fund?

Subtract what you already have saved from your target, then divide the remaining gap by how much you can set aside each month. Saving $400 a month toward a $12,000 gap takes 30 months. Increasing the monthly amount is the fastest way to shorten that — the calculator updates instantly so you can test different amounts.

Where should I keep an emergency fund?

Somewhere safe and quickly accessible — typically a separate high-yield savings account, not invested in stocks. The goal is availability and capital safety, not growth: you need to be able to withdraw it the day an emergency hits, without risk of it having dropped in value.
