Emergency Fund Calculator

By Sarah Li Cain | September 18, 2025

You probably know that you should have an emergency fund, but how much do you really need in the bank in case an unexpected, financially draining event occurs? An emergency fund calculator can help you figure that out.

Most experts recommend that you have at least three to six months’ worth of basic living expenses in the bank.

This amount can seem daunting, but remember, you aren’t expected to have it set aside in one lump sum. You will save up to reach this goal. And if you can’t accumulate that amount, know that something (anything) is better than nothing. Don’t feel defeated and not save at all. If you can put away $1,000 over the course of a year, do it.

Having adequate savings can get you ready for a worst-case scenario and give you peace of mind. So read on, and use this emergency fund calculator to help you prepare properly for a rainy day.

Calculator Definitions

• Rent or mortgage: This expense only includes the amount you pay to your landlord or mortgage lender. If you put money into an escrow account for taxes, include that amount as well. Property taxes and PMI may be factors to add, too.

• Utilities: Consider using an average amount you pay for bills such as electricity, sewage and water, as some months may be higher or lower than others.

• Telecom charges: Costs include internet, phone (landline and/or mobile access), and other related expenses.

• Insurance: This can include health, car, and homeowners insurance. If you included homeowners insurance above (as part of the escrow charges), eliminate them here.

• Transportation: Includes expenses such as parking fees, gas, car maintenance, public transportation, and toll expenses.

• Credit card and/or loan payments: Put all non-mortgage debt here, including car loans, personal loans, student loans, and minimum monthly credit card payments.

• Food: Include your usual costs, such as food from grocery stores vs. spending lavishly on dining out.

• Other costs: Any necessities you pay aside from any of the above categories can go here. Expenses can include daycare fees, child support, medications, and uniforms required for work.
