SAVING · ON YOUR DEVICE
Emergency fund calculator
Add your essential monthly costs and a months-of-cover goal. See your target, your gap and a timeline.
EXAMPLE ESTIMATE

Enter your values and select Calculate.
Estimates use your assumptions. Calculations use unrounded values; displayed figures are rounded.
HOW IT WORKS
A useful estimate starts with clear inputs.
- Step 1
Add your essential monthly costs, the ones you must pay even without income.
- Step 2
Choose how many months of cover you want and enter what you have already saved.
- Step 3
Calculate to see your target, your gap and how long it takes to reach it at your monthly saving.
Essential costs of 2,500 a month and a 6-month goal give an emergency fund target of 15,000.
Calculation assumptions and limits
The target is essential monthly costs times the months you choose. Savings grow at the interest rate you enter, compounded monthly, with contributions added at month-end. Income taxes, changing prices, unexpected one-off costs and any benefits you may receive if you lose income are excluded.
Can I use this with my local currency?
Yes. All inputs in one calculation must use the same currency. The currency selector changes number formatting and labels; it does not look up exchange rates or convert your amounts. Local loan rules and products may calculate costs differently.
Are my numbers saved?
No. Your inputs and results stay in this page’s memory. Reloading or leaving clears them. Download the CSV or print the result if you want a copy.

Size your safety net from your real essential costs
An emergency fund covers the bills you must pay if income stops or a large unexpected cost arrives. The right size depends on your essential spending, not your total spending, and on how stable your income is.
Enter your essential monthly costs, choose how many months of cover you want, and add what you have already saved. The calculator shows your target, how many months of cover you have today, the gap, and how long it will take to close it with the monthly amount and interest rate you enter. A table shows the 3, 6, 9 and 12 month levels.

A practical example
Essential costs of 2,500 a month and a 6-month goal give a target of 15,000.
Before you finish
Count only costs you must pay if income stops. Keep the fund somewhere you can reach quickly.
Why essential costs, not total spending
If your income stops, you will cut non-essential spending quickly. The fund needs to cover only what you cannot avoid: housing, utilities, food, transport, insurance, minimum debt payments and similar bills. Using essentials gives a target you can actually reach and a fund that lasts longer than the same amount measured against total spending.
How many months of cover?
Three months suits a stable job with a second income and low fixed costs. Six months is a common general target. Nine to twelve months suit freelancers, single earners, people in volatile industries or those with dependants. The table in your results shows what each level would be for your numbers and which levels you have already reached.
Building it faster
Automate a transfer on payday so saving happens before spending. Put windfalls, such as tax refunds, straight into the fund. The timeline in the result shows how the monthly amount changes the date. If it is longer than you want, review your costs with the budget planner.
When to use it
Use the fund for real emergencies such as job loss, urgent repairs or medical bills, then rebuild it. Keep long-term goals in a separate account so the safety net stays intact. The savings goal calculator works well for those other goals.
Frequently asked questions
How many months should an emergency fund cover?
Three months is a common starting point and six is widely used. People with variable income, one earner or dependants may prefer nine to twelve.
What counts as essential spending?
Housing, utilities, food, transport to work, insurance, minimum debt payments and similar costs you cannot skip. Subscriptions and dining out usually do not count.
Where should I keep an emergency fund?
In an account you can reach quickly that is not exposed to market swings, such as a savings account. Check the rules and any deposit protection where you live.
Should I build the fund before paying off debt?
Many people build a small starter fund first, then pay down expensive debt. It depends on your situation, so use the debt calculators to compare.
Does the calculator include interest?
Yes. Enter the annual interest rate on your savings and it is compounded monthly. Set it to 0% for a simple timeline.
Does the fund have to be in cash?
It should be easy to reach and low risk. Many people use a savings account. Money that can lose value quickly is not ideal for an emergency fund.
