How to estimate a personal loan payment

Enter the amount you will borrow, the fixed annual interest rate and the term in months. Enter any separately paid upfront fee, then try an optional extra monthly payment. The results separate borrowed principal, interest and fees so a lower monthly payment does not hide a higher lifetime cost.

Interest rate, APR and origination fees

Use the nominal interest rate for this calculation, not a fee-inclusive APR. A separately paid fee increases the estimated borrowing cost but does not increase the financed balance or the regular installment. If a lender deducts an origination fee from your proceeds or finances it, check the agreement: this model does not automatically reproduce that treatment.

Choosing a term and testing extra payments

A longer term usually lowers the scheduled payment while increasing total interest at the same rate. Try the actual term you have been offered, then test an extra amount you can afford consistently. Extra principal starts with the first payment and is capped at the amount owed. The model excludes prepayment penalties and late fees; check your lender’s rules before relying on the savings.

Worked example

For a hypothetical $25,000.00 balance at 8.5% over 60 months, the modeled first debt payment is $512.91 and total interest is $5,774.80. No extra payment is included.

Common questions

Does the calculator include an upfront fee?

Yes, as a separately paid cost. It is not added to the financed loan balance.

Is the result a loan offer?

No. It is an educational fixed-rate monthly estimate, not approval, underwriting or a lender quote.
