How to use this result

Start with the decision, then inspect the assumptions.

Accelerated biweekly payments are usually half the monthly payment every two weeks. That creates the equivalent of 13 monthly payments each year, compared with 12 monthly payments.

How the calculation works

The monthly payment is calculated with Canadian compounding. The accelerated-biweekly payment is one-half of that amount, applied 26 times per year using the biweekly periodic rate.

For the full notation, rate conversion, rounding approach, and limitations, see the calculation methodology.

Worked Canadian example

Put the estimate in context

If a monthly payment is CA$2,800, the accelerated-biweekly payment is roughly CA$1,400. Over a year, that is CA$36,400 rather than CA$33,600, causing principal to fall sooner.

Before relying on it

Common mistakes

  1. 01Confusing regular biweekly with accelerated biweekly.
  2. 02Comparing payment amounts without comparing annual totals.
  3. 03Assuming all lenders define accelerated schedules identically.
  4. 04Ignoring whether the higher annual cash flow fits the budget.

Clear answers

Frequently asked questions

Is accelerated biweekly always exactly half monthly?

That is the common convention used here. Confirm the lender’s definition and rounding.

Why does it save interest?

More money is paid each year and principal falls sooner, so less interest accrues later.
