Loan calculator.
Estimate your monthly payment and total interest before you apply. Switch between personal, debt consolidation, auto, and mortgage loans. Move the sliders.
Principal vs Interest Over Time
How much of each payment goes to principal vs interest, month by month
Estimates only. Actual rates and terms come from individual lenders and depend on your credit, income, state, and other factors. Not an offer of credit. Checking real rates uses a soft inquiry and won't affect your credit score.
How to read the numbers.
Monthly payment vs. total interest
Most borrowers focus on the monthly payment, which is reasonable — that's the number that shows up in your budget. But two loans with the same monthly payment can have wildly different total costs. A longer term lowers the monthly payment but raises the total interest paid over the life of the loan. The calculator shows both: monthly payment up top (large), total interest in the secondary block. Look at both before you compare lenders.
APR — the apples-to-apples number
APR (Annual Percentage Rate) includes the interest rate plus most lender fees, especially origination fees on personal loans. That's why APR is the comparison number — not just the headline interest rate. Two lenders may quote the same interest rate but very different APRs because of fee differences. When the marketplace returns offers, focus on APR side-by-side.
Debt consolidation savings — read carefully
When you switch to the Debt Consolidation tab, the calculator adds two extra sliders: current card balance and current card APR. It estimates how long the cards would take to pay off if you only made minimum payments (≈2% of balance), and compares that total cost to the consolidation loan you're configuring above. The "estimated savings" is the difference. It's an approximation — your actual card payoff trajectory depends on the issuer's specific minimum-payment formula and any new charges you put on the card.
What this calculator does not do
The calculator estimates a single fixed-rate, fully-amortized loan. It does not model: variable-rate loans (HELOCs, adjustable-rate mortgages), interest-only periods, balloon payments, prepayment scenarios, lender-specific fees beyond the embedded assumptions, taxes (for mortgage), insurance (for auto and mortgage), or PMI. For mortgage in particular, the real monthly housing payment will include escrow for taxes and insurance on top of principal and interest.
