How to Calculate a Student Loan Payoff Date
Before taking on student loan debt, every student needs to know how much their monthly payment will be and how long they will be paying off the debt. You can use our student loan calculator above to calculate the monthly payment on a student loan.
The payoff calculator above can help you figure out if you will be able to afford the student loan payments. Since student loans function like other amortized loans, you can also use a loan payoff calculator to calculate the payoff date.
How to Calculate Loan Interest and Principal
Once you know the monthly payment, you can determine what portion of the payment goes towards interest and what portion goes to principal.
The formula to calculate the interest portion of the payment is:
Where:
P = remaining principal balance
r = periodic interest rate
The formula to calculate the principal portion of the payment is:
Where:
PMT = payment amount
P = remaining principal balance
r = periodic interest rate
Let’s try an example using the calculator. Let’s assume you have a student loan of $30,000 which will be paid at 8% annual interest with a monthly payment of $500.
To find the periodic interest rate, divide the annual interest rate of 8% by 12, which equals 0.6667%.
In this example, the first interest payment will be $200. You can find this by multiplying $30,000 by 0.6667%.
$30,000 × 0.006667 = $200
Repeat this step each month as the remaining principal balance gets lower.
The amortization schedule shows that this loan will be paid off in 6 years and 5 months. You can use an amortization calculator to see the principal and interest payments for each month.
The principal payment is just the monthly payment minus the interest payment. For the first month in our example, the monthly payment is $500 and the interest payment is $200.
Therefore, the principal payment will be $300.
To calculate the monthly payment on a loan, use a loan payment calculator.
How to Estimate Early Payoff Dates
The estimated payoff date is slightly less than the inverse of the increase in payment. To estimate an early payoff date, try the formulas above with a higher payment amount and repeat the steps to calculate the payoff date for the new payment amount.
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 time.
In our example, we would pay off the loan in 6 years and 5 months with a $500 payment. If we double the payment to $1000, the payoff time is 2 years and 10 months.
If the payment is $1,500 per month, the payoff time is 1 year and 10 months.
Frequently Asked Questions
How Much Do Extra Loan 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 balance 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 $500 in our example paid $300 towards the principal.
If you increase the monthly payment to $600, that extra $100 goes straight to the principal balance, so now $400 goes to pay down the principal balance. This is repeated each month.
The faster the principal balance 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 because the interest payments are based on the remaining principal balance.
What is a student loan payoff?
A student loan payoff is the full payoff amount required to pay off the student loan in full. This includes the principal balance and any accrued interest.
Should you pay off your student loans in full?
Whether to pay off your student loans in full or not is a personal decision that depends on each person’s financial situation. However, paying off a student loan in full will save the borrower a significant amount of money in interest that would have been accrued over the life of the loan.
