Loan Worksheet

Amortization Calculator

See your monthly payment, the full amortization schedule, and how much sooner you'd be debt-free by paying extra — every month, once, or both.

1Loan details

The basic terms of the loan.

months

0 = a brand-new loan. If you're partway through, enter how many monthly payments you've already made — everything below then projects forward from today.

month
year

This is "today" — used to show real payoff dates (like "Nov 2044") instead of just a length in the results.

2Extra payments

Optional — see how much sooner you'd pay this off.

$
same payment, either way
$

Required payment is $0. Fill in either box above — the other updates automatically.

Default of 1 means the extra starts right away. Raise it (e.g. 13) to delay the extra/higher payment until that payment number, then it applies from there on.

$

Payment #12 = 12 payments from today (not from the original loan start) — so if you're partway through, #1 is your very next payment. This is specifically for the one-time lump sum above; it updates itself to fit your loan term until you change it yourself.

3Escrow & other costs

Optional — these don't change your payoff schedule, but they're part of what actually leaves your account each month.

Add property tax, insurance, PMI, HOA…

4Refinance

Optional — only affects anything if you expand this and enter a new rate.
