Planning a boat purchase? The boat loan calculator separates price, down payment, financed or upfront purchase costs and an annual boating reserve from the loan payment.
For an installment loan with a quoted origination fee or monthly insurance, use the personal loan calculator to separate disbursement, net cash available and modeled borrowing costs.
Loan payment calculator
Use the amortized-loan section for a conventional fixed-payment installment loan. Enter principal, annual interest rate, term, compounding frequency, and payment frequency to calculate each payment, total payments, total interest, and the full amortization schedule.
payment = P x r x (1 + r)^n / ((1 + r)^n - 1)
In the formula, P is principal, r is the effective rate for each payment period, and n is the number of payments. When the rate is zero, payment equals principal divided by the number of payments.
Fixed-payment loan example
A $100,000 loan at a 6% annual interest rate, compounded monthly and repaid monthly over 10 years, has a payment of about $1,110.21. Across 120 payments, total paid is about $133,224.60 and total interest is about $33,224.60.
Amortization schedule
Each fixed payment first covers interest on the remaining balance; the rest reduces principal. Early payments contain more interest because the balance is larger. Later payments shift toward principal. The schedule shows payment, principal, interest, and ending balance for every period.
Deferred payment loan
Use the second model when principal and interest accumulate until one amount is due at maturity. It compounds the entered principal for the selected term and frequency without periodic payments.
amount due = principal x (1 + annual rate / compounds per year)^(compounds per year x years)
Bond or predetermined due amount
Use the third model when the future amount due is known and you need its present value. The result discounts the future value back over the selected term using the entered rate and compounding frequency.
present value = future amount / (1 + annual rate / compounds per year)^(compounds per year x years)
Interest rate versus APR
The calculator treats the entered percentage as the nominal rate used in the selected compounding model. A disclosed APR can include certain fees and may not equal the note interest rate. The Consumer Financial Protection Bureau explains that APR is intended to reflect the interest rate plus additional loan charges.
Compare total cost, not only payment
A longer term can reduce each payment while increasing total interest. CFPB guidance recommends comparing amount financed, APR or rate, term, monthly payment, and total cost. Origination, documentation, insurance, late, and other fees are not included unless they are already part of the principal you enter.
Frequently asked questions
Is this also a loan payment calculator?
Yes. The amortized-loan model calculates periodic payment, total interest, total paid, and an amortization schedule.
Can payment frequency differ from compounding frequency?
Yes. The calculator converts the entered annual rate into an effective rate for the selected payment interval.
Does the result include fees?
No. Add financed fees to principal if appropriate and compare the result with the lender's legally required disclosures.
Can I use it for mortgages or auto loans?
The basic amortization math applies, but dedicated mortgage and auto loan tools include costs specific to those products.
