Bi-Weekly Mortgage Payment Calculator FAQ
- Can I include property tax, home insurance, and PMI in the calculation?
- Yes, the calculator has dedicated fields for yearly property tax, yearly home insurance, and PMI (until a specified date). These are added to the biweekly payment total for a complete cost picture.
- How does the biweekly payment accelerate payoff compared to monthly payments?
- Biweekly payments result in the equivalent of 13 monthly payments per year instead of 12, which reduces the principal faster and shortens the loan term, saving interest over time.
- What extra payment options are available?
- You can enable one-time or recurring extra payments, specify the dollar amount, and set a start date. The tool updates the amortization schedule and projected payoff date accordingly.
- Can I download or print the payment schedule?
- Yes, the calculator generates an amortization schedule that can be downloaded as an Excel or PDF file for all payments grouped by year.
