Finance Tools

Money math is easy to get wrong by hand. A small slip in an interest rate or a loan term can cost you hundreds of dollars. These finance calculators do the math for you and show the result in seconds. You enter a few numbers and get a clear answer.

Each tool does one job well. The loan calculator shows your monthly payment and total interest. The compound interest calculator shows how savings grow year by year. The tip calculator splits a bill across a group. No tool tries to do everything, so each one stays simple to use.

You also see the full breakdown, not just the final number. A loan result includes the payment, the interest you pay, and a month by month schedule. That detail helps you compare two offers and pick the cheaper one. It also shows where your money goes each month.

Every calculator runs in your browser. Nothing gets saved and no account is needed. You can run the same numbers with different inputs and compare results side by side. Try a bigger down payment, a shorter term, or a lower rate, and watch the payment change.
