Student loans come with more moving parts than most debt, deferment periods, income-driven repayment, sometimes multiple loans with different rates. This calculator handles the core math for a single loan at its current terms: enter your balance, rate, and payment to see your real payoff date.
If you have multiple student loans
Run each loan through this calculator separately to see them individually, or use our full debt payoff calculator if you want to compare avalanche versus snowball order across all of them at once. Federal loans in the US often have different rates from private loans, so it’s worth checking rates on each loan you hold before deciding which to prioritize.
Income-driven repayment and this calculator
This tool assumes a fixed monthly payment, the way a standard repayment plan works. If you’re on an income-driven repayment plan, your actual payment may change as your income changes, which this calculator won’t predict. Use your current payment amount for a snapshot of where you’d land if nothing changes, not a guarantee of your actual future payment.
Frequently Asked Questions
Should I pay off student loans before saving for retirement?
This depends on your loan’s interest rate compared to what you’d realistically earn investing instead, plus whether your employer offers any retirement match. There’s no universal answer. A nonprofit credit counselor or fee-only financial advisor can help you weigh this for your specific numbers, see our directory by country.
Does this calculator account for loan forgiveness programs?
No, this calculator only models standard fixed-payment payoff. Forgiveness programs (like Public Service Loan Forgiveness in the US) work on entirely different rules tied to your employer and payment count, not a payoff date. Check your loan servicer or program administrator directly for forgiveness-specific guidance.
What happens if I pay extra on a student loan?
Extra payments reduce your principal directly, the same as any other loan, which reduces the interest charged in future months. Some servicers apply extra payments to future installments by default rather than principal, so check that your servicer is applying extra payments to principal, not just paying you ahead on the existing schedule.
