How it's calculated
This calculator models the standard repayment plan: a fixed monthly payment over a fixed term, using the same amortization formula as any other installment loan.
It does not model income-driven repayment plans, deferment, forbearance, or loan forgiveness programs — those involve rules and eligibility that vary by loan type and change over time, so they're out of scope here. Use this as a baseline for what you'd pay under a standard fixed schedule.
Federal student loans typically offer standard terms of 10 years, though extended and graduated plans exist. Private student loans vary by lender.
Worked example
A $30,000 student loan at 5.5% interest on a standard 10-year repayment plan comes out to a monthly payment of about $325.58.
Over the full term, that loan accrues $9,069.46 in total interest, bringing the total amount repaid to $39,069.46.
Frequently Asked Questions
- Does this include income-driven repayment plans?
- No. This calculator models only the standard fixed-payment repayment plan. Income-driven plans adjust your payment based on income and family size and can result in a different total cost — check with your loan servicer for those figures.
- What's a typical student loan term?
- Federal standard repayment is typically 10 years. Extended repayment plans can run 20-25 years, which lowers your monthly payment but increases total interest paid.
- Should I pay extra toward my student loan?
- Extra payments reduce your principal faster and cut total interest, similar to any other loan. If you have multiple debts, the Debt Payoff Calculator can help you decide where extra payments do the most good.
