Debt & Loan Calculators

Free tools to plan your mortgage, pay off credit cards faster, and understand your loan payments. See exactly when you'll be debt-free.

The real cost of borrowing

Debt can make a big purchase possible, but the monthly payment is only part of the story. Interest, fees, loan length, and extra payments all change the real cost. These calculators put those numbers in front of you before they become a surprise.

Use the mortgage and down payment tools to sanity-check a home purchase. Use the credit card and debt payoff calculators to see how long a balance sticks around. If you are looking at refinancing, the break-even point is the number to watch.

The goal is not to make every loan sound scary. It is to make the tradeoffs plain enough that you can choose the term, payment, or payoff plan with your eyes open.

Common questions

What does a mortgage payment include?
Mortgage payments typically include Principal (loan amount), Interest (cost of borrowing), Taxes (property taxes), and Insurance (homeowners insurance), often abbreviated as PITI. Our mortgage calculator focuses on principal and interest for the core payment, but you should factor in taxes and insurance when calculating true monthly housing costs. These vary a lot by location and property value.
What is APR vs. interest rate?
The interest rate is the percentage of principal charged for borrowing. APR (Annual Percentage Rate) includes the interest rate plus fees and other costs, representing the true annual cost of the loan. When comparing loans, APR is a more accurate comparison tool. Our calculators use standard interest rates, so compare against loan APRs when evaluating real-world options.
How much does making extra payments help?
Extra payments can reduce payoff time and interest, especially on high-interest debt. Try the minimum payment first, then add a little more and compare the payoff date. The difference is often clearer than any lecture about debt.
Should I refinance my mortgage?
Refinancing makes sense when new interest rates are a lot lower than your current rate, and when the monthly savings will exceed refinancing costs before you plan to move. Our mortgage refinance calculator compares your current loan to new terms and shows your break-even point in months. Generally, you want to break even within 3-5 years for it to be worthwhile.
