How to use this personal loan calculator
Enter the amount you plan to borrow, the nominal annual interest rate, and the repayment term. The calculator estimates a fixed monthly principal-and-interest payment. Switch on the optional sections to include an origination fee, a monthly service charge, or an extra principal payment plan.
How monthly payments are calculated
The calculator assumes a fixed rate and equal monthly payments. Each month, interest is calculated on the opening balance. The rest of the scheduled payment reduces principal. The final payment is adjusted to the remaining amount due. Extra principal reduces later interest by lowering the remaining balance sooner.
View the payment formula
For principal P, monthly rate r (annual nominal rate divided by 12), and n monthly payments, the scheduled payment is P × r ÷ (1 − (1 + r)−n). At 0% interest, payment is P ÷ n. A financed origination fee is added to P before the payment is calculated. An upfront or deducted fee does not change P.
The estimated fee-inclusive APR solves for the monthly rate that equates net proceeds with the standard scheduled payments and modeled service charges, then multiplies that rate by 12. It is a comparison estimate, not a regulatory disclosure. Lender rounding, dates, and local APR rules can produce a different result.
Origination fee options
An upfront fee is paid separately at the start. A deducted fee reduces the cash you receive but leaves the loan balance at the requested amount. A financed fee is added to the balance and is repaid with interest. The results show the fee and interest separately so you can compare cash proceeds and the all-in borrowing cost.
Comparing extra payments
The standard schedule and extra-payment plan use the same scheduled installment. Optional monthly and one-time extra amounts are applied to principal after the normal payment. The last payment is capped at the amount due, and payments after payoff are excluded. The comparison shows how the plan changes total interest and payoff time.
Service charges
An optional monthly service charge is added to each month’s cash outflow while the loan is active. It does not reduce principal and is not included in the scheduled payment. Actual lenders may treat recurring fees differently; use the contract’s fee rules when comparing offers.
Questions and limitations
How is the estimated APR calculated?
It uses the standard schedule, net loan proceeds after any upfront or deducted fee, and modeled monthly service charges. Extra voluntary payments are excluded. Use a lender’s official disclosure for the contractual or legally defined APR.
Can I use a 0% rate?
Yes. Set the annual rate to zero. The principal is divided evenly across the term, with any financed fee included in that principal.
