PMI. You can ask your servicer to cancel private mortgage insurance when your balance is scheduled to reach 80% of the original value of your home, and the servicer must end it automatically at 78%, as long as you are current on payments. This calculator ends PMI when the balance, including your extra payments, reaches 78% of the home price.

Frequently asked questions
How much does paying biweekly save?
On the example $320,000 loan at 6.5% for 30 years, it saves $93,073 in interest and ends the loan 5 years and 10 months early.
Why do biweekly payments pay the loan off faster?
There are 26 two-week periods in a year, so you make 26 half payments, which is 13 monthly payments. The 13th goes straight to principal.
How is the biweekly option calculated here?
As one extra monthly payment a year, spread over the 12 months: one-twelfth of your payment is added to principal each month. Real plans differ in when the money is applied, so ask your servicer.
How biweekly mortgage payments work
Paying half of your monthly payment every two weeks makes 26 half payments a year, which equals 13 full monthly payments instead of 12. The extra month of payments goes to principal. On a $320,000 loan at 6.5% for 30 years, the monthly payment of $2,022.62 becomes $1,011.31 every two weeks. The 6.5% rate is an example, not today’s rate. Enter your own in the mortgage calculator.
What it saves
The calculator models it as one-twelfth of your monthly payment ($168.55) added to principal each month. That pays the loan off in 24 years and 2 months instead of 30 years and saves $93,073 in interest.

Check with your servicer
Not every servicer accepts payments every two weeks. Some hold the half payments until a full one is due, which removes most of the benefit, and some charge a setup fee. You can get the same result by adding one-twelfth of your payment to every monthly payment or making one extra payment a year.
