Why Make Extra Payments on Your Mortgage?

Making extra payments on your mortgage can offer several advantages:

  • Save on Interest: By reducing your loan principal faster, you decrease the amount of interest you pay over time. The more you pay upfront, the less interest you’ll accrue on the remaining balance.
  • Pay Off Your Loan Faster: Extra payments shorten the term of your loan, allowing you to pay off your mortgage earlier than expected, giving you financial freedom sooner.
  • Lower Loan-to-Value Ratio: Paying off your mortgage faster increases your home equity, which could allow you to refinance at better rates in the future.
  • Build Wealth Sooner: Paying down your mortgage gives you more disposable income in the long run, allowing you to invest in other opportunities or save for retirement.

How Extra Payments Affect Your Mortgage

Extra payments on your mortgage have a significant impact on both your monthly payment and the total interest paid. Here’s how they work:

  • Principal Reduction: Extra payments go directly toward reducing the principal of your loan, which in turn reduces the amount of interest you are charged in the following months.
  • Shortened Loan Term: By applying extra payments to your mortgage, you shorten the term of the loan, allowing you to pay off your mortgage early and reduce your total interest costs.
  • Interest Savings: The faster you reduce the principal balance, the less interest you’ll pay over the life of the loan, which can result in significant long-term savings.

Frequently Asked Questions About Mortgage Extra Payments

How much can I save by making extra mortgage payments?

Extra payments can save you thousands in interest and shorten your loan term significantly. For example, on a $300,000, 30-year mortgage at 4% interest:

  • $100 extra/month saves $28,000+ and pays off 4 years early
  • $500 extra/month saves $67,000+ and pays off 11 years early
The savings compound because you're reducing principal faster, which reduces future interest calculations.

When is the best time to make extra mortgage payments?

The earlier you make extra payments, the greater the impact:

  • Early in loan term: Maximum interest savings (most of early payments go toward interest)
  • After rate drops: When refinancing to a lower rate, maintain original payment amount
  • Windfalls: Use bonuses, tax refunds or inheritances for lump-sum principal reductions
Even small regular extra payments early on have an outsized impact.

Should I pay extra on principal or refinance to a shorter term?

Compare both options:

Extra Payments Shorter Refinance
Flexibility High (can stop anytime) Low (fixed higher payment)
Interest Rate Keeps current rate Gets current market rate
Closing Costs None 2-5% of loan
Extra payments offer more flexibility unless rates have dropped significantly.

How do I ensure my extra payments go toward principal?

Follow these steps:

  1. Contact your lender about their process for principal-only payments
  2. Specify in writing "Apply to principal only" with each extra payment
  3. Verify on statements that principal is being reduced appropriately
  4. Consider sending payments separately from regular payment
Some lenders automatically apply overpayments to next month's payment unless instructed otherwise.

Are there any downsides to making extra mortgage payments?

Potential considerations include:

  • Liquidity: Money tied up in home equity is less accessible
  • Opportunity cost: Might earn more investing elsewhere (especially if mortgage rate is low)
  • Prepayment penalties: Rare, but check your loan documents
  • Emergency funds: Don't sacrifice your safety net
For most homeowners, the psychological benefit of faster payoff outweighs these factors.

How do lump sum payments compare to regular extra payments?

Both strategies are effective:

  • Regular extra payments: Create consistent progress and budgeting habit
  • Lump sums: Make bigger immediate impact but require discipline to repeat
  • Combination: Many homeowners do both (small regular extra + occasional larger payments)
$1,000/year extra saves similar interest whether paid as $83/month or $1,000 annually.

Should I pay off mortgage early or invest the extra money?

Consider these factors:

  • Mortgage rate vs investment returns: Paying off a 6% mortgage is like earning 6% risk-free
  • Tax deductions: Mortgage interest may be deductible (limits apply)
  • Risk tolerance: Paying off debt is guaranteed while investments fluctuate
  • Age: Those nearing retirement often prioritize being debt-free
Many financial advisors suggest a balanced approach - some extra payments while also investing.
