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.

This tool can take into account your usual monthly expenses to come up with the right figure. For instance, are you paying a couple of hundred dollars a month in rent in a small town, with roommates, or are you paying a considerable amount for a mortgage on your dream home? A calculator can take that and other variables into account so you can stash away the right amount.

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.
