How long could your savings cover the essentials?

This calculator tells you how many months of essential expenses your liquid savings could cover and whether that runway falls in a red, yellow, or green range.

Calculate your runway

Housing, basic food, utilities, insurance, transport, and minimum debt payments.
Cash you can reach quickly without selling long-term investments.

What to do with the number

A short runway can help you set a concrete next target. A long runway may mean you can direct future savings toward other priorities, but the right buffer still depends on job security, insurance, dependents, health needs, and access to other support.

This range is a common rule of thumb, not financial advice. It is a starting point for deciding how much uncertainty you want your cash reserve to absorb.

Emergency fund questions

What counts as essential expenses?

Include costs you would still need to pay during an income interruption: housing, basic food, utilities, insurance, transportation, and minimum debt payments. Leave out spending you could pause.

What counts as liquid savings?

Use cash you can access quickly without selling long-term investments, commonly money in checking, savings, or a money market account.

Why does income stability change the target?

Variable and seasonal income can make a longer gap between reliable paychecks more likely, so the tool raises both thresholds by 50%.

Should I include retirement accounts?

Usually not. Retirement money can involve taxes, penalties, or market losses when withdrawn, so this calculator does not treat it as liquid savings.
