How to use this calculator
- 1Choose whether to estimate the time to a goal or the monthly saving needed by a target date.
- 2Enter current liquid emergency savings and either one essential-expense total or a detailed monthly breakdown.
- 3Select an editable coverage target, optional extra buffer, APY, and the contribution or dates required by the chosen mode.
Formula
Emergency fund target = monthly essential expenses × target coverage months + additional buffer
Savings grow using the entered APY converted to an effective monthly rate, with contributions added at month end.
Calculation steps
- Add the selected essential monthly expenses.
- Multiply the monthly total by the editable coverage-month target and add the optional extra buffer.
- Compare current liquid emergency savings with the target and calculate current months of expense coverage.
- Convert APY to an effective monthly rate.
- Either simulate month-end contributions for up to 100 years or solve the annuity formula for the selected target date.
- Separate new contributions from estimated savings growth and compare 3-, 6-, 9-, and 12-month expense amounts.
Worked example
With 3,000 in essential monthly expenses, a six-month target, and a 1,000 extra buffer, the modeled emergency-fund target is 19,000 before comparing current savings and future contributions.
Assumptions
- The target coverage period is a user-selected planning assumption, not a universal recommendation.
- Only liquid money deliberately entered as emergency savings is counted.
- APY remains constant and contributions are added at the end of each monthly period.
- A partial final calendar month is treated as one monthly saving period in target-date mode.
- Currency selection changes formatting only and does not convert values.
- Taxes, account restrictions, inflation, fees, and changing expenses or income are excluded.

Frequently asked questions
How many months of expenses should I choose?
Choose a target that reflects your own household, income stability, insurance, obligations, and likely emergencies. The comparison amounts are planning references, not personal advice.
What expenses should be included?
Include expenses you expect to keep paying during a financial shock, such as housing, food, utilities, transport, insurance, healthcare, minimum debt payments, and caregiving.
What does APY mean here?
APY is treated as an effective annual savings yield and converted to an equivalent monthly growth rate. Actual account yields can change.
Are my expense details shared?
No. Detailed financial inputs are not written into the URL; sharing includes the canonical calculator page and a result summary only.
Is this financial advice?
No. It is a deterministic planning calculation based only on the values entered and does not recommend an account, target, or financial action.
