How to calculate your emergency fund
Target = necessary monthly expenses × chosen months. Amount still needed = target − available cash, with a minimum of zero. A savings timeline divides that gap by your monthly contribution and rounds up.
A $2,500 monthly budget example
A 3-month target is $7,500. With $2,000 saved, the gap is $5,500. Adding $400 at the end of each month takes 14 contributions to reach the target, assuming no withdrawals.

How much emergency fund do I need?
Choose the number of months of necessary expenses you want to cover. This calculator multiplies your monthly essential costs by that number. The right target depends on your situation; the month buttons are examples to compare, not a personal recommendation.
How do I calculate a 3-month or 6-month emergency fund?
Multiply necessary monthly expenses by 3 or 6. At $2,500 per month, those targets are $7,500 and $15,000. These amounts cover the entered essentials only, not every possible emergency.
What expenses should I include?
Include housing, basic food, utilities, necessary transport, insurance and minimum debt payments. Add a monthly share of predictable annual bills. For a personal budget, enter your share; for a shared budget, count combined expenses once.
Can I build an emergency fund while living paycheck to paycheck?
Start by checking whether your current income covers spending. The contribution field is a plan you enter, not a finding that you can afford it. If there is a monthly shortfall, an ongoing savings plan needs a change in income or expenses to be sustainable.
How long will it take to build my emergency fund?
Divide the amount still needed by your planned monthly contribution and round up to the next whole month. We assume a contribution at the end of each month, no withdrawals and no interest. A zero contribution cannot close a positive gap.
Should I count all my savings?
Use accessible cash available for the people in this budget. Exclude credit limits and money committed elsewhere. Shared cash also appears in the other tools; do not count the same money twice. Investment returns and withdrawal costs are not modeled.
Does reaching my target mean I am financially safe?
Reaching your chosen target means your cash covers that amount of entered necessary expenses. It does not predict medical bills, accidents, job loss or insurance coverage, and it is not permission to spend any extra cash.
What is the difference between an emergency fund and savings runway?
An emergency fund target is an amount you want to keep. Savings runway estimates how long existing cash could last under a spending and income scenario. Use the savings runway calculator to explore that separate question.
Where does the data come from, and can I save my results?
