Bi-weekly Loan Calculator with Payment Frequency Comparison

Bi-Weekly Loan Calculator Sign

This calculator will calculate the payment amount and total interest charges for a biweekly loan, and then present you with the first year payment schedule.

Plus, the calculator will also help you to compare the payments and interest charges to other payment frequencies (monthly, bi-monthly, quarterly, semi-annually, and annually).

Note that if you have an existing loan that you are making monthly payments on and you would like to see how much you could save by switching to a biweekly payment method (making 26 half-payments per year), please visit the Biweekly Loan Payment Calculator.

Why biweekly is cheaper, but not the cheapest.

Biweekly is Usually Cheaper

Given the same repayment time-frame and loan interest rate, choosing a bi-weekly loan over other popular loan repayment frequencies will usually result in the lowest interest cost. That's because the balance that the interest is charged on is declining more often.

To understand why increasing loan repayment frequencies reduces interest costs -- all other terms being equal, think of a loan as the lender renting the use of each dollar bill they borrow to you. This means that the sooner you return a dollar bill you are renting, the less rent you will be charged on that dollar.

For example, if you are making annual payments, then you will be renting the same number of dollars during the entire year -- giving the lending institutions more time to charge you rent on each dollar.

On the other hand, if you return a portion of the rented dollars periodically throughout the year, the rent you will be charged will be less than the rent charged on the annual payment frequency. And the faster you return the dollars, the lower your annual rental charges will be.

The Best of All Payment Frequencies

What is the cheapest of all payment frequencies? Biweekly? Weekly? Daily? No, it's actually ...


In other words, if you save up and pay cash for the item you are considering purchasing you will only end up making one payment, and you will end up paying $0.00 in interest charges.

In my opinion, if you don't want a non-essential product bad enough to save up and pay cash for it, you don't want it bad enough to be purchasing it in the first place.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
