Should I make extra
mortgage payments?

Every dollar of extra principal you pay reduces the balance that accrues interest the following month. Over time, this compounds: less interest means more of your regular payment goes to principal, which further reduces the balance. The snowball effect is real.

One extra payment per year on a typical 30-year mortgage can shave 4 to 5 years off the loan. Consistent monthly additions do even more. The calculator below lets you see exactly what your numbers look like.

None of this is in dispute. The math works. The question this page asks is different: is this the best use of that money given everything else in your financial life?

When you send extra money to your mortgage, that money does not disappear from the universe if you choose not to. It goes somewhere else. The real comparison is not "prepay vs. do nothing." It is "prepay vs. the next best alternative."

Economists call this opportunity cost: the value of the thing you gave up by choosing one option over another. If your mortgage rate is 3% and you can safely earn 4.5% in a high-yield savings account, every dollar you prepay is earning 1.5% less than it could be earning elsewhere, with no risk.

If you carry a credit card balance at 22%, the gap is enormous. Paying off that card is a guaranteed 22% return. Prepaying a 6.5% mortgage while carrying 22% debt is like choosing a 6.5% investment when a 22% investment is sitting right next to it.

And if you are not maximizing your pre-tax 401(k) contributions, the math is even more compelling. Every dollar you contribute reduces your taxable income immediately (saving you your marginal tax rate) and then grows tax-deferred. The combined first-year value can exceed 30% depending on your bracket. That is money working far harder than a mortgage prepayment ever could.

When you send extra money to your mortgage, it becomes part of your home equity. That sounds good until you need it back. You cannot withdraw equity without selling the home, refinancing, or taking out a second mortgage or HELOC (all of which have costs, take time, and are never guaranteed to be available).

If you lose your job, face a medical expense, or find an investment opportunity, the money you prepaid is inaccessible. A savings account or brokerage account gives you the same ability to build wealth with full liquidity. You can access it tomorrow if you need to.

This matters especially if you might sell or refinance within a few years. You will get your equity back at sale regardless of whether you prepaid. Home appreciation does most of the work. The extra payments just meant you had less flexibility along the way, earning your mortgage rate as a return on money you could not touch.

This page is not anti-prepayment. There are real scenarios where extra mortgage payments are a strong financial move. The key is that the decision should be made after evaluating all your options, not in isolation.

A mortgage payment does not exist in isolation. It sits alongside credit card debt, car loans, retirement savings, emergency funds, and life goals. Whether extra mortgage payments are the best use of an extra dollar depends on your whole financial picture, not one loan's amortization schedule.

The following are considerations worth evaluating. They are not ranked in order because the right priority depends on your situation, your rate, and your goals.

None of these considerations is universally more important than the others. Someone with a 7.5% mortgage, no other debt, and a fully funded emergency fund is in a very different position than someone with a 3% mortgage and available 401(k) space. The point is to evaluate extra mortgage payments against everything else in your financial life, not in isolation.

If you are unsure how these considerations apply to your situation, this is a conversation worth having with a financial advisor who can look at the full picture: your income, tax bracket, existing debts, retirement savings, and goals. They can help you determine where your extra dollars will have the most impact.
