Bi-Weekly Payment Calculator by TheCalcTools

How the Bi-Weekly Payment Calculator works

Enter your balance, rate and remaining term.

The monthly payment is split in half and paid every two weeks, giving 26 half-payments a year.

That is one extra monthly payment a year, which pays the loan off faster.

The formula

n = −ln(1 − P × r ÷ pay) ÷ ln(1 + r), with r = APR ÷ 26 and pay = monthly ÷ 2

Worked example

Using the default values shown in the calculator:

Loan balance$300000
Interest rate (APR %)6.5 %
Remaining term (years)30
  1. Monthly payment on $300,000 at 6.5% for 30 years = $1,896.20.
  2. Bi-weekly: $948.10 every two weeks pays it off in about 24.1 years.
  3. That saves roughly 5.9 years and $88,122 in interest.

Result:

Monthly payment$1,896.20
Bi-weekly payment (half the monthly)$948.10
Payoff time, bi-weekly (years)24.1
Time saved (years)5.9
Interest saved (approx.)$88,122

Frequently asked questions

Does my lender accept bi-weekly payments?

Some do, some charge a fee, and some only apply the money once a month. Alternatively, add one-twelfth of your payment to each monthly payment for a similar effect.

Is the saving real?

Yes, because you make the equivalent of 13 monthly payments each year, though the exact amount depends on how the lender applies payments.
