How this calculator works
Twenty-six half-payments a year add up to thirteen monthly principal-and-interest payments instead of twelve, so one extra payment a year goes to principal; each half-payment is assumed to be credited the day it is paid. Payoff time and interest saved depend only on the loan. Property tax (your rate times the price) and insurance are added once per month (annual amount ÷ 12) and once per bi-weekly payment (÷ 26); they never shorten the loan. PMI and HOA dues are not included.

Frequently Asked Questions
Do bi-weekly mortgage payments really save money?
Yes, if your servicer applies each half-payment when it arrives. The thirteenth monthly payment each year goes straight to principal, which is why a 30-year loan at 6.75% is paid off several years early. If your servicer holds half-payments until the full monthly amount arrives, you get the same effect by adding one-twelfth of a payment to each monthly payment.
Does where I live change the savings?
Only through the price you pay. The interest saved depends on the loan amount, rate and term, which work the same way in every state. Property tax and insurance change what you pay every two weeks but not how fast the loan is paid off; the table below shows both for each state's median-priced home.
