Personal loan calculator
Calculate the payment, total interest and fee-adjusted cash cost of an unsecured personal loan. Enter the exact offer you are considering; rates, terms and fees vary by lender and borrower.
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
Use the APR from the lender disclosure for the offer you are comparing. APR can include certain fees; do not substitute a generic rate range or a separate interest-rate quote.
- 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 principal and interest plus the amount of cash delivered after an entered origination fee. Compare the result with the competing offer's APR, fees, payment and payoff plan.
How to compare personal loan offers
Compare offers using the same borrowed amount and term. Check the APR, cash received after any origination fee, monthly payment, total of payments, late or prepayment fees, and the lender's current disclosure. The CFPB APR explanation and its personal-installment-loan fee guidance explain why a headline interest rate is not enough for a cost comparison.
- APR: use the rate in the written offer, including disclosed charges where applicable.
- Cash received: subtract an origination fee from the gross principal when the lender deducts it upfront.
- Total cost: compare all scheduled payments and fees for the same payoff horizon.
When a personal loan makes sense
- Debt consolidation: compare the loan's APR and total cost with the existing balances, transfer fees and payoff schedule.
- Major home repair: compare the payment and total cost with available cash, home-equity products and contractor financing.
- Medical bills: ask about provider payment plans before adding a new loan, then compare the written loan disclosure if borrowing remains necessary.
- Other planned or unexpected expenses: confirm that the payment fits the budget and that the loan's total cost is acceptable.
Watch for origination fees
An origination fee may be deducted from the proceeds while the scheduled payments still repay the gross principal. Borrow $20,000 with a 5% fee and you receive $19,000 before other charges, but the payment schedule is based on the loan terms. Enter the fee here, then compare the lender's disclosed APR and net amount received. The CFPB fee guidance lists questions to ask before accepting an installment loan.
