How to pay it off faster
Three ways to shorten a mortgage and cut interest.
Extra monthly payments
Adding even $100–$300 a month goes straight to principal once the required interest is covered, which compounds into years of savings over a 30-year loan.
One-time lump sum
Applying a bonus, tax refund, or inheritance to principal in a single month permanently lowers the balance every future payment is calculated against.
Bi-weekly payments
Paying half your monthly payment every two weeks adds up to 26 half-payments a year — the equivalent of one extra full payment annually.
Common questions
Frequently asked questions
Is PMI always required?
No. Private mortgage insurance is typically only charged when your down payment is under 20% of the home’s price. Once your loan balance reaches 78% of the original home price, lenders are required to automatically cancel PMI under the Homeowners Protection Act — this calculator models both the requirement and the automatic cancellation.
How accurate are these estimates?
This tool estimates principal, interest, taxes, insurance, HOA dues and PMI based on the numbers you enter. Actual lender quotes may include origination fees, discount points, escrow cushions, or mortgage insurance calculated differently. Use this as a planning starting point, then confirm exact figures with a loan estimate from your lender.
Does bi-weekly really save money?
Paying half your monthly principal-and-interest payment every two weeks results in 26 half-payments a year — the equivalent of 13 monthly payments instead of 12. That extra payment goes entirely to principal, which is why it shortens the loan and reduces total interest. Confirm with your loan servicer that extra payments are applied to principal immediately and don’t carry a prepayment penalty.
