How Extra Mortgage Payments Save You Money
Making extra payments on your mortgage is one of the most powerful ways to build wealth and achieve financial freedom faster. Every extra dollar you pay goes directly toward reducing your principal balance, which means less interest accrues over the life of your loan. The earlier you start making extra payments, the more you'll save.
Our extra mortgage payment calculator shows you exactly how much you can save with either regular monthly additions or one-time lump sum payments. The results might surprise you — even an extra $100 per month can shave years off your mortgage and save tens of thousands in interest.
Monthly Extra Payments vs. Lump Sum: Which Is Better?
Both strategies can significantly reduce your mortgage costs, but they work differently:
- Extra Monthly Payments — Consistent, budget-friendly approach that builds momentum over time. Ideal if you have steady extra income each month. The compounding effect is powerful because you're continuously reducing your principal.
- Lump Sum Payments — Great for windfalls like tax refunds, bonuses, or inheritances. A single large payment immediately drops your principal, reducing all future interest calculations. Especially effective early in your mortgage when interest charges are highest.
- Combination Strategy — Many homeowners use both: consistent extra monthly payments plus occasional lump sums when extra cash is available. This maximizes flexibility and savings.
When to Pay Extra vs. Invest Instead
The "pay extra on mortgage or invest" debate depends on your specific situation. Consider paying extra on your mortgage if:
- Your mortgage interest rate is relatively high (above 5-6%)
- You value the guaranteed "return" of eliminating debt
- You want the security of owning your home outright
- You're risk-averse and prefer certainty
Consider investing instead if:
- Your mortgage rate is very low (below 4%)
- You haven't maximized tax-advantaged accounts (401k, IRA)
- You have a long time horizon and can tolerate market volatility
- You need liquidity (extra mortgage payments are less accessible)
How to Make Extra Mortgage Payments
Most lenders make it easy to pay extra, but it's important to specify that additional funds should go toward principal, not toward future payments. Here's how:
- Online Portal — Most lenders have an option to make additional principal payments online. Look for "additional principal" or "extra payment" options.
- Written Instructions — Include a note with your payment specifying "Apply to principal only."
- Bi-weekly Payments — Some lenders offer bi-weekly payment programs that result in one extra monthly payment per year.
- Check Your Statement — After making extra payments, verify your statement shows the principal balance decreased by the full extra amount.
Prepayment Penalty Warning
Before making extra payments, check if your mortgage has a prepayment penalty. Most conventional mortgages don't, but some loans — especially certain FHA loans or mortgages from smaller lenders — may charge a fee for paying off early. Read your loan documents or call your lender to confirm.
Frequently Asked Questions
The savings depend on your loan balance, interest rate, remaining term, and extra payment amount. On a $250,000 mortgage at 6.5%, adding just $200/month can save over $45,000 in interest and cut nearly 5 years off your loan. Use our calculator to see your specific savings.
Both strategies save money. Lump sum payments are more effective early in your mortgage when interest is highest. Monthly extra payments build consistent savings over time. Mathematically, the sooner you pay extra — in any form — the more you save.
It depends on your mortgage rate, investment options, and risk tolerance. If your mortgage rate is above 5-6% and you value guaranteed returns, extra payments make sense. If your rate is very low and you have tax-advantaged investment accounts available, investing may yield higher long-term returns. Many financial advisors suggest a balanced approach.
Extra payments should go entirely toward principal, not interest. Always specify "apply to principal" when making extra payments. This directly reduces your balance, which reduces all future interest charges. Check your statement to confirm proper application.
Most conventional mortgages don't have prepayment penalties, but some do — especially certain FHA loans or mortgages from smaller lenders. Check your loan documents or contact your lender before making large extra payments to confirm no penalties apply.
The earlier, the better. In the first years of a mortgage, most of your payment goes to interest. Extra principal payments early on have the biggest impact because they reduce the balance that interest is calculated on for all remaining years.
