Personal loan calculator
Calculate the true monthly cost of a personal loan. Unsecured, fixed-rate, 2–7 year terms from $1,000 to $100,000. Best for debt consolidation and large planned purchases.
How to Calculate a Personal Loan Payment
Find your true monthly payment, total interest, and origination-fee-adjusted APR on any personal loan in four steps.
- Step 1Enter the loan amount
Use the principal you want to borrow (e.g., $20,000). If the lender charges an origination fee, the cash you actually receive is principal × (1 − fee%); enter the gross principal here.
- Step 2Enter the APR
2026 APR by credit tier: 740+ FICO → 9–11%, 670–739 → 13–17%, 620–669 → 18–24%, sub-620 → 25%+. Always quote APR including origination fee, not the lower 'interest rate' figure.
- Step 3Set the term in years
Standard 2–7 years. Shorter term raises monthly payment but cuts total interest in half. 60-month vs 36-month on a $20K @ 11% loan: $435 vs $655/month, but $6,098 vs $3,605 total interest.
- Step 4Read monthly payment and total interest
The calculator shows fixed monthly P&I and lifetime interest cost. Compare against credit card balance-transfer math: 0% APR cards beat personal loans for 12–21 months if you can pay off in that window.

When a personal loan makes sense
- Debt consolidation: swap 22% credit card APR for 10–12% loan APR. Save thousands if you actually pay it off and don't reload the cards.
- Major home repair: roof, HVAC, plumbing — when you can't tap home equity.
- Medical bills: avoid 18% medical credit cards by switching to 8–12% personal loan.
- Funeral, moving, large unexpected expense: better than putting on credit cards.
Watch for origination fees
Lenders like LendingClub and Upstart charge 3–10% origination fees deducted from your loan proceeds. Borrow $20,000 with a 5% origination fee = receive $19,000 but pay back $20,000. The effective APR is meaningfully higher than the quoted APR. LightStream, Marcus, and Discover charge zero origination — easier comparison.
