Estimate your monthly payment and total interest across the life of a loan.

Start from a monthly payment you can manage and see how much you could borrow at terms from one to seven years.

See the true annual cost of borrowing once fees are folded into the rate.

Work out the interest rate you need to hit a target monthly payment.

Compare two loan offers for the same amount to see which costs less.

Your credit range drives a loan’s rate and cost — see what moving up could save.

Compare your current loan with a new rate and term to see what you could save.

See how paying extra each month or a lump sum now saves you interest and time.

See whether you’ll clear a credit card or hit its limit once interest, spending and any annual fee are in the mix.

See what moving your balance to a 0% card would save you once the transfer fee and the rate after the offer ends are counted.

Add up your cards to see how much of your available credit you’re using — overall and per card.

Add up your debts to see when you’ll be debt-free and how much interest you’ll pay at your current payments.

See whether rolling your debts into one loan clears them sooner and costs less than paying them off the way you are now.

Compare the debt snowball and avalanche methods to see which clears your debts sooner and costs less in interest.

Blend the snowball and avalanche methods — quick early wins first, then your highest rates — and see exactly what the hybrid costs and saves.

Kill every debt above a rate you set first, then snowball the rest — and see what putting the expensive debt first costs and saves.

Set the order you pay your debts off in — a family loan or a co-signed card first — and see what your order costs against snowball and avalanche.

Watch a balance grow with simple versus compound interest, and see how the compounding frequency changes the result.
