# Biweekly Mortgage Payment Calculator

With Comparison Payment Schedule

## What is a biweekly mortgage?

Borrowers usually pay mortgages monthly. However, with a biweekly loan, borrowers must pay every other week.

Why would I want a biweekly loan?

You should consider a biweekly payment plan because you'll save on interest charges over its term. Additionally, while you'll naturally make more payments with a biweekly loan, you'll pay the loan off sooner than with a monthly payment plan.

How will a biweekly mortgage reduce the interest amount paid?

The payment amount for a biweekly mortgage is one-half the monthly amount. Since there are 52 weeks in a year, you'll make 26 regular payments when paying every other week. That's the same as making 13 monthly payments.

To put some numbers on this, if the monthly payment is \$2,000, the mortgage holder will pay \$24,000 a year when paying monthly. Or when paying biweekly, they'll pay \$26,000 (\$2,000 / 2 = \$1,000 * 26 = \$26,000) a year.

So the mortgage holder is paying more per year (the amount equal to one monthly payment), and the benefit to them for doing so is they'll be debt free sooner and the total interest paid will be lower.

How much will you save with a biweekly payment plan?

The amount you save depends on the total amount of the loan and the interest rate. The higher the amount or interest rate, the more you'll save in absolute terms. Use this calculator to calculate your particular savings. More details below

## Monthly vs. Biweekly Payment

Without a doubt, an accelerated biweekly mortgage will save you money vs. a monthly mortgage. As the above illustration show, it's a mathematical certainty.

But, no matter how you slice it, monthly or biweekly, mortgages are significant investments for most of us. Over the term of the loan, the total interest charges at a 5% interest rate will exceed 60% of the original loan amount.

For a \$325,000 loan, total interest comes to more than \$300,000 for the monthly option and \$247,000 for the biweekly option. Sure, saving more than \$50,000 with the biweekly option is excellent, but \$247,000 is still a lot!

Can anything be done to reduce the loan costs any further?

Perhaps there is.

## Biweekly Mortgage Calculator with Extra Payments

If you have the available cash flow, you can make extra payments which are used to reduce the loan balance. When you decrease the amount owed, you lower the amount of interest due. Doing this is called prepaying principal.

Even making one extra payment will save you interest. This calculator supports both lump sum or one-time extra payments as well as a series of additional payments.

To see how much you'll save, you may apply the extra payment to either the monthly loan or the biweekly loan, or both. The idea here is, you may want to compare a debt paid biweekly without additional payments to a debt paid monthly, where you do plan to make extra payments.

Or you may want to see how much the biweekly loan will save over the conventional loan when you add extra payments to get an additional saving boost.

Note: In keeping with the theme of this calculator, the extra payment for the biweekly loan will be 1/2 the amount you enter. This is an intentional design feature, not a bug!

A biweekly loan will save you money.

A biweekly loan and making extra payments will save you even more money.

But is doing either the right, long term, financial strategy?

### Forgone Opportunity Costs - They Could Cost You!

At the top of this post, when explaining how a biweekly payment loan works and how it saves interest charges, I showed you some simple arithmetic. In the example, if you, the borrower, elects to pay every other week, you'll pay \$2,000 more per year than if you make 12 monthly payments.

You should ask yourself, what else could you be doing with the \$2,000?

Could you be investing it?

If you make biweekly payments, you lose the opportunity to invest them. Not being able to save and invest is a forgone opportunity. It does not come back.

The question then is, if you invested the \$2,000, how much would it earn over the term of the biweekly loan? Would you gain more than you expect to save interest charges?

Several calculators on this site will answer these questions for you. This Savings Calculator is a good place to start.

What you want to know is what will be the future value of \$2,000 invested every year for the next 22 years or so (typically the term of the biweekly loan at today's interest rates). If the future value is more than that amount you save in interest, then perhaps you should not take out a biweekly mortgage?

Remember though, there are usually risks to investing, while the interest saved with a biweekly mortgage or loan is a mathematical certainty.

### Charts

If you are like me, you'll get tired of staring at columns of numbers. That's where charts come into play. Take a look at the recently updated charts to get a quick summary of all the details you'll find in the amortization schedules.

This calculator includes six of them.

If you are a blogger, feel free to export () any of the charts you create and to post them on your site to help prove your point!

• ##### Rose Fifesays:

When applying a lump sum payment to reduce balance of a land contract, should a new amortization schedule be done, using the old balance minus the payment? Or do you just calculate the amount as a number of payments and pick up the schedule down the payment line?

• ##### Karlsays:

Just deduct the lump sum from the principal, and continue on with the schedule.

• ##### Rose Fifesays:

Shouldn’t the payment reduce a little due to reducing balance in same time frame of original land contract?

• ##### Karlsays:

The payment could be reduced, but it doesn’t have to be. This depends on what the lender and the borrower agree on.

If the payment is not reduced, then the loan will be paid off faster than if it is reduced. Normally, if the loan is issued by a commercial lender, their software (and the loan agreement) is not set up to reduce the payment. If the borrower wants the payment reduced, they would have to pay off the loan and negotiate a new loan on the new, lower balance.

But again, my comments are only generalities. The specifics can and do vary.

• ##### Karlsays:

One other thing, I’m not sure why you are using the biweekly payment calculator, since your questions are not about biweekly loans, per se. If you want to use a calculator that has the ability to recalculate a new payment after a lump sum extra payment, you can use this calculator. It might take a bit of effort to learn how to use it for your particular calculation, but if you decide to try it and have questions, just ask. The calculator can create an amortization schedule with the payment changing or not changing. If you create both, then you can compare the differences.
