Paying an extra $100 a month on a 15-year mortgage directly reduces your principal balance, which shortens your loan term and saves thousands in interest. By applying this extra amount toward the principal, you can reduce the overall repayment time by several months to over a year, depending on the interest rate, and accumulate equity faster.
By paying more than your required monthly mortgage payment, you can put that extra money directly toward the principal amount on your loan. Your interest payment is based on your principal balance, so by applying your extra payment to your principal, you could pay less in interest over time.
If your mortgage rate is similar or higher than your savings rate, overpaying can be beneficial. Considering the current financial climate can help you make your decision. For example, if interest levels on saving deposit accounts are low, using spare cash to pay extra on your mortgage may make more sense.
Increasing your monthly payments, making bi-weekly payments, and making extra principal payments can help accelerate mortgage payoff. Cutting expenses, increasing income, and using windfalls to make lump sum payments can help pay off the mortgage faster.
Dave Ramsey strongly advocates for 15-year, fixed-rate mortgages as the quickest path to wealth, emphasizing lower total interest, faster equity building, and less debt, asserting that if you can't afford the higher payments, you can't afford the house; he recommends buying with cash if possible, but a 15-year loan is the preferred borrowing option, keeping your payment under 25% of your take-home pay.
When you make an extra payment or a payment that's larger than the required payment, you can designate that the extra funds be applied to principal. Because interest is calculated against the principal balance, paying down the principal in less time on your mortgage reduces the interest you'll pay.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
Time your Mortgage Overpayments
Your interest could be calculated daily, monthly, quarterly, or annually. If your mortgage interest is calculated daily, then you can make mortgage repayments at any time. However, if it isn't, Sprive suggests you make the payment a day before the interest is calculated.
To pay off a 25-year mortgage in 10 years, you need to make significant extra principal payments through strategies like increasing monthly payments, making bi-weekly payments (effectively one extra payment a year), applying windfalls (bonuses, refunds) as lump sums, or refinancing to a shorter term, focusing on early payments to maximize interest savings.
To pay off a 30-year mortgage in 10 years, you must aggressively pay down the principal with strategies like increasing monthly payments significantly, making bi-weekly payments (effectively one extra payment yearly), applying lump sums from bonuses/refunds, and potentially refinancing to a shorter-term loan, all while ensuring extra funds go directly to the principal to save thousands in interest.
The main downsides of prepaying are tying up cash that could earn more elsewhere (like investments), potential prepayment penalties from lenders, reduced liquidity for emergencies, and missing out on the time value of money, especially if your loan interest rate is low; it also means losing potential tax deductions and can complicate financial aid.
The biggest drawback to a 15-year mortgage is the higher monthly payments that come with it. Although these mortgages come with lower interest rates, they also come with heftier monthly expenses that you'll have to budget for because you're basically paying your house off in half the time of a 30-year loan.
Not Putting Extra Payments Toward the Loan Principal
Otherwise, you may not see much progress in your early mortgage payoff efforts because your extra payments will be absorbed by interest.
If you have a lower interest rate on your mortgage than on your savings account (for example, your mortgage is 3% and your savings is 6%), it makes financial sense to save with the higher interest rate savings account rather than overpay your mortgage.
The "10/15 mortgage rule" is a strategy to pay off a 30-year mortgage in about 15 years by consistently paying an extra 10% of the principal amount each month (or equivalent weekly/bi-weekly payments), significantly reducing total interest and achieving homeownership much sooner, though it requires significant discipline and financial commitment. It works by accelerating principal repayment, which cuts down the loan term and interest, effectively transforming a 30-year loan into a 15-year one.
Paying an extra $500 a month on your 15-year mortgage drastically shortens your loan term, saves you tens of thousands in interest, builds equity faster, and helps you become mortgage-free years sooner, effectively turning your 15-year loan into a much shorter one, potentially paying it off in less than 10 years depending on your loan details.
