When to use this calculator
Use this biweekly mortgage payment calculator to compare monthly payments with regular or accelerated biweekly payments. It is useful if you are paid every two weeks or want to see how payment frequency may affect cash flow and interest.

Accelerated biweekly payment = monthly mortgage payment / 2
- Mortgage amount is the principal being financed.
- Rate and amortization estimate the equivalent monthly payment.
- Accelerated biweekly payments create 26 half-payments per year.
Worked example

Common mistakes
- Confusing regular biweekly and accelerated biweekly payments.
- Assuming all lenders calculate payment frequency savings the same way.
- Forgetting to check whether the higher annual payment fits your budget.
FAQs
Why can accelerated biweekly payments save interest?
They usually result in the equivalent of one extra monthly payment per year, which can reduce principal faster.
Are biweekly payments always better?
They can help, but only if the payment schedule fits your income timing and budget.
Does this replace an amortization schedule?
No. It gives a payment comparison, while a full amortization schedule shows principal and interest over time.
