recommendation for how to handle your finances. Consult with a financial professional before making financial decisions. Learn how we calculated this below ## On this page: ## How to Calculate a Mortgage Payoff Date A mortgage payoff date can be calculated when you know the remaining loan balance, interest rate, and monthly mortgage payment. The calculator above can show you how much faster you can pay off your home mortgage if you pay more than the monthly payment. Both our loan payoff calculator and the payoff calculator above can be used to calculate this. ### Formula to Calculate Interest Paid per Payment Mortgage interest can be calculated in a two-step process. First, the annual interest rate must be divided by 12 to obtain a periodic interest rate. Then the remaining principal balance will be multiplied by the periodic interest rate to calculate the monthly interest payment. The formula below summarizes the interest payment formula: interest = P \times r Where: P = remaining principal balance r = periodic interest rate For example, let’s assume you have a loan with a loan balance of$300,000, an annual interest rate of 4%, and a monthly payment of $2,000. Therefore, the periodic interest rate is 0.33% (4% divided by 12). The payoff calculator above shows that the mortgage will be paid off in 17 years and 5 months. You can use our loan payment calculator to figure out the payment. The first interest payment will be found by multiplying the principal balance of$300,000 by the periodic interest rate of 0.33%. This comes out to $1,000. The remaining principal balance fell to$299,000 after the first payment. If we multiply this new amount by 0.33%, we get an interest payment of $996.67 for the second mortgage payment. This is exactly what the amortization table shows. Try our amortization calculator to build an amortization schedule. As this shows, the interest payment decreases with each mortgage payment. This is because the principal balance falls every time a payment is made. As the remaining principal balance falls, the interest payment will fall as well. The final mortgage payment of$2,000 will have an interest payment of $8.57. ### Formula to Calculate Principal Paid per Payment The principal payment is calculated by subtracting the monthly interest payment from the monthly mortgage payment. The formula below summarizes this: principal = PMT − (P \times r) Where: PMT = payment amount P = remaining principal balance r = periodic interest rate In the example above the first interest payment was$1,000. Since the mortgage payment is $2,000, the principal payment will also be$1,000. The second interest payment fell to $996.67, so the second principal payment increased to$1,003.33.

In this case, the principal payment increased. With every payment that occurs, the principal payment will be larger than the previous principal payment.

Since the mortgage payment is fixed and because the interest payment declines, the principal payment must therefore increase. The final mortgage payment of $2,000 has a principal payment of$1,991.43.

## How to Estimate an Early Payoff Date

The estimated payoff date is slightly less than the inverse of the increase. For example, if you plan on doubling the monthly payment, the payoff date will be less than half the time. If the monthly payment is tripled, the payoff date will be slightly less than a third of the original payoff date.

In our example, we would pay off the loan in 17 years and 5 months with a $2,000 payment. If we double the payment to$4,000, the payoff time is 7 years and 3 months. If the payment becomes $6,000 per month, the payoff time is 4 years and 7 months. ## How Much Do Extra Mortgage Payments Help? There are two reasons why extra payments reduce the time it takes to pay off a loan. First, it automatically increases the amount that goes to the principal each month. Also, it reduces future interest payments because the remaining principal balance will be smaller at each time period. Let’s look at each of these in more detail. First, the principal payment automatically increases. The first payment of$2,000 in our example paid $1,000 towards the principal. If we increase the monthly payment to$2,100, that extra $100 goes straight to the principal balance, so now$1,100 goes to pay down the principal balance. This is repeated each month. The faster the principal payment goes down, the faster the loan will be paid off in full.

Also, as the remaining principal balance goes down faster, the future interest payments will also be less. This is because interest payments are based on the remaining principal balance.

Both of these work together to reduce the loan payoff time when extra payments are applied to the loan.

Let’s look back at our examples and compare the principal and interest payments of the 3rd payment when we pay $2,000 or$2,100 per month.

With a $2,000 monthly payment, the third payment calls for a principal payment of$1,006.68 and an interest payment of $993.32. With a$2,100 monthly payment, the third payment calls for a principal payment of $1,107.35 and an interest payment of$992.65.

As you can see, the amount that pays down principal is almost $101 greater with a$2,100 monthly payment, even though we only pay an extra \$100 a month.

This difference is even greater the further we are in the amortization schedule.
