Emergency savings planning

Emergency Fund Calculator

Turn essential monthly expenses into a reserve target, estimate when the current savings plan may reach it, and calculate the contribution needed for a chosen deadline.

Include expenses that would continue during an income interruption.
The comparison table also shows 3-, 6-, and 9-month scenarios.
Applied immediately before monthly contributions begin.
Assumed to arrive at the end of each month.
Enter 0% when interest should be excluded.
Used to calculate the monthly contribution needed by the deadline.

Your emergency-fund target

The target equals essential monthly expenses multiplied by the selected reserve period. The starting reserve includes current savings and the one-time contribution.

Reserve target — Essential expenses multiplied by reserve months
Starting reserve — Current savings plus the one-time contribution
Target funded — Starting reserve as a percentage of the target
Remaining gap — Amount still needed before future interest

Current savings plan

This estimate applies the entered APY and monthly contribution until the reserve reaches the selected target.

Estimated completion — Estimated time to the target
Monthly contributions used — Contributions through the estimated completion month
Estimated interest — Interest earned before the target is reached

Reach the target by your deadline

The deadline calculation keeps the same target, starting reserve, and APY. It solves for the end-of-month contribution needed.

Contribution needed — Estimated monthly contribution for the deadline
Change from current plan — Difference from the planned monthly contribution
Current plan at deadline — Projected reserve using the current monthly plan
Deadline — Entered deadline period

Compare 3-, 6-, and 9-month reserves

These scenarios use the same expenses, starting reserve, APY, monthly contribution, and deadline. They provide comparison points rather than a universal recommendation.

How this emergency-fund calculator works

Reserve target Essential monthly expenses × reserve months
Effective monthly rate (1 + APY)^(1 ÷ 12) - 1

The current-plan estimate compounds the starting reserve monthly and adds the regular contribution at each month-end. The deadline calculation uses the same timing.

The result does not determine which expenses are essential, how many reserve months a household needs, or whether money should be redirected from debt payoff, retirement, insurance, or another goal.

Interest rates can change. Taxes, account fees, withdrawal restrictions, deposit-insurance limits, and account-specific rules are outside this calculation.
