Calculate a loan payment
Calculating a loan payment uses principal, annual rate and either term or payment as knowns. The Payment Calculator switches modes so the unknown matches the question. Solve-payment mode amortizes over a fixed number of years. Solve-term mode finds how many periods a chosen payment needs.
QuickCalculators shares the amortization engine with the Loan Calculator while targeting the payment keyword.
Fees and insurance outside the loan amount need separate budgeting.
Solve for the payment on a fixed term
Solving for the payment on a fixed term applies the standard amortization formula. The Payment Calculator needs principal, rate and years. A $20,000 loan at 6% for five years produces a level monthly payment that clears the balance on schedule.
QuickCalculators can also show the amortization schedule so interest and principal split are visible.
Higher rates or shorter terms raise the payment; longer terms lower it and usually raise total interest.
Solve for the term on a fixed payment
Solving for the term on a fixed payment finds how many months are required at the given rate. The Payment Calculator needs principal, rate and the monthly payment amount. If the payment is at or below accruing interest, the balance does not shrink and no finite term exists.
QuickCalculators surfaces that limit so an unaffordable payment plan is not mistaken for a payoff path.
Larger payments shorten the term; smaller payments lengthen it until the interest floor blocks progress.

Correct a common misconception: any payment above zero eventually pays the loan
A common misconception is that any payment above zero eventually pays the loan. Payments at or below monthly interest leave the balance flat or growing. The Payment Calculator flags that case when solving for term.
Frequently asked questions
How does the Payment Calculator work?
The Payment Calculator either finds the monthly payment for a fixed term or finds the term for a fixed payment, using principal and rate in both modes.
How is a loan payment calculated?
A loan payment is calculated with the fixed-payment amortization formula on principal, monthly rate and number of months. The Payment Calculator uses that formula in solve-payment mode.
How is loan term calculated from a payment?
Loan term is calculated from the relationship between principal, rate and payment, solving for the number of periods. The Payment Calculator returns that term when the payment can amortize the loan.
How is this different from the Loan Calculator?
The Loan Calculator also covers deferred and bond-style structures. The Payment Calculator focuses on solve-payment and solve-term for amortizing loans.
What if the payment is too low?
If the payment is too low to cover interest, the loan does not pay off at that amount. The Payment Calculator indicates that the term cannot be solved usefully.
Summarize the Payment Calculator
The Payment Calculator solves either the monthly payment or the payoff term for an amortizing loan from principal and rate. QuickCalculators keeps the maths exact to the cent and labels results as estimates, not loan offers.
