Mortgage Payoff Calculator
Find how long until a mortgage is paid off.
See how long a mortgage takes to clear at a given monthly payment.
The math behind it
months = −ln(1 − r×balance ÷ payment) ÷ ln(1 + r), with r the monthly rate. The payment must exceed the monthly interest.
Worked example
$200k at 6%, $1,500/mo → ~166 months (13.8 yr).
FAQ
