Can I add extra payments?

This version shows the baseline schedule. Use a payoff/extra-payment tool to model prepayments.

Does this include taxes/insurance?

No. It shows principal and interest only.

Not modeled. This assumes fixed-rate, fully amortizing monthly payments.

Can I export the schedule?

Yes—download the table if you need CSV/print (template supports rendering the schedule rows).

No. Add PMI/taxes/insurance separately to see full escrowed payment.

Inputs explained

Loan amount: Principal financed.
APR: Annual percentage rate for the loan.
Term: Length of the loan in years.

How it works

Monthly payment uses the standard amortization formula with your loan amount, APR, and term.

Each month: interest = balance × monthly rate; principal = payment − interest; balance reduces until paid off.

We total interest across the schedule and provide a downloadable table (principal, interest, balance) per month.

Formula

Payment = P × r / (1 − (1+r)^{−n}) where r = APR/12, n = term months
Interest_m = Balance × r
Principal_m = Payment − Interest_m
Balance_{m+1} = Balance_m − Principal_m

When to use it

Checking mortgage, auto, or personal loan payoff patterns.
Seeing how much of each payment is interest vs principal early vs late in the term.
Comparing total interest across different terms or rates.

Tips & cautions

Shorter terms raise the payment but cut total interest sharply.
Even small rate drops make a big difference over long terms—compare scenarios.
Use extra payments to accelerate payoff; this tool shows the baseline schedule.
Assumes fixed-rate, fully amortizing monthly payments; no balloons or adjustable rates.
Does not include taxes, insurance, PMI, or fees rolled into the loan.
Extra payments not modeled in this version (baseline schedule only).
