Your payment depends on your loan type, repayment plan, and total balance
Student loan payments are not one-size-fits-all. The amount you owe each month depends on which federal program your loans came from, which repayment plan you chose (or defaulted into), how much you borrowed, and the interest rate attached to each loan. A borrower with $30,000 in federal loans might pay $300 a month on a standard plan or $150 on an income-driven plan—or $0 if their income is low enough. Private loans work differently and usually have no income-based options.
The fastest way to find your actual payment is to log into your loan servicer's website or call them directly. They hold the real numbers: your current balance, interest rate, remaining term, and which plan you're on. If you haven't chosen a plan yet, or you're trying to estimate before you borrow, the federal loan simulator and your servicer's payment calculator will show you what different plans would cost.
Key Takeaways
- Federal loans on the standard 10-year plan cost roughly 1% of your total balance per month, but income-driven plans can be much lower or zero depending on your earnings.
- Your payment amount changes if you switch repayment plans, so the plan you're on now is not necessarily the plan you'll stay on.
- Private student loans have no income-based options and usually require a fixed monthly payment from the start of repayment.
- Interest accrues daily on unsubsidized loans, so the longer you delay payments, the more you owe when payments begin.
How federal loan payments are calculated by plan type
Federal student loans come with several repayment plans, and each calculates your payment differently. The Standard Repayment Plan spreads your loan over 10 years with equal monthly payments. You can estimate this by dividing your total loan balance by 120 (the number of months). A $30,000 loan would be roughly $250 per month before interest is added; the actual payment will be higher because interest accrues on the unpaid balance.
Income-driven plans—SAVE, PAYE, IBR, and ICR—calculate your payment as a percentage of your discretionary income (your income minus 150% or 225% of the federal poverty line, depending on the plan). On SAVE, the newest plan, the percentage is 5% to 10% of discretionary income. On older plans like PAYE and IBR, it's 10% to 15%. If your income is low enough, your payment can be $0, though interest still accrues on unsubsidized loans. These plans also offer forgiveness after 20 to 25 years of payments.
The Graduated Repayment Plan starts with a lower payment that increases every two years, finishing in 10 years. This suits borrowers who expect their income to rise. The Extended Repayment Plan stretches payments over 25 years, lowering the monthly amount but increasing total interest paid.
Where to find your current payment amount
Your loan servicer is the organization that collects your payments. You can find out who services your federal loans by logging into studentaid.gov and viewing your loan details, or by calling the Federal Student Aid Information Center at 1-800-4-FED-AID (1-800-433-3243). Your servicer's website will show your current balance, interest rate, repayment plan, and the exact monthly payment you owe.
If you have private student loans, contact the lender directly—the bank or company that issued the loan. Your promissory note or loan agreement states the payment amount and schedule. Private lenders do not use income-driven plans, so your payment is usually fixed for the life of the loan unless you refinance.
If you have not yet entered repayment, your servicer can show you what different plans would cost. Many servicers offer a payment calculator on their website where you can enter your loan balance and see estimates for each plan. The federal government also runs the Repayment Estimator at studentaid.gov, which pulls your actual loan data and shows payments under each federal plan.
How interest affects what you actually pay
Interest is added to your loan balance every day, and your payment covers both principal (the amount you borrowed) and interest. On federal loans, interest accrues at a fixed rate set by Congress—rates vary by loan type and year borrowed, ranging from roughly 5% to 8% in recent years. On private loans, rates can be fixed or variable and are set by the lender based on your credit score.
The longer you wait to pay, the more interest accumulates. If you have unsubsidized federal loans and you're in school or deferment, interest still accrues. When you enter repayment, that accrued interest is capitalized—added to your principal balance—which means you'll pay interest on the interest. On income-driven plans, if your payment is $0 or lower than the interest accruing, unpaid interest capitalizes annually, growing your balance even though you're making payments.
This is why the payment you calculate today might not match the payment you owe in six months. If you're in school now and have unsubsidized loans, your balance will be higher when repayment starts. If you're on an income-driven plan and your income changes, your payment will change too.
What happens if you change repayment plans
You can switch federal repayment plans at any time by contacting your servicer or logging into your servicer's website. Changing plans does not reset your loan or forgive any balance—it only changes how your remaining balance is divided into monthly payments. If you move from a 10-year standard plan to a 25-year extended plan, your monthly payment drops but you pay more interest overall. If you move to an income-driven plan, your payment may drop to $0, but interest still accrues and capitalizes annually.
Switching plans makes sense if your income drops, if you want a lower monthly payment, or if you're pursuing forgiveness (which requires staying on an income-driven plan for 20 to 25 years). It does not make sense if you can afford your current payment and want to minimize total interest paid—staying on the shortest plan you can afford costs less overall.
Private student loans and fixed payments
Private loans do not have income-driven repayment options. Your payment is set when you sign the promissory note and is usually fixed for the life of the loan. The lender calculates it based on the loan amount, interest rate, and term (usually 5 to 20 years). You can find your payment on your loan statement or by logging into your lender's website.
Some private lenders offer forbearance or deferment while you're in school, which pauses payments but allows interest to accrue. Once repayment begins, you owe the full monthly payment unless you refinance with a different lender. Refinancing is the only way to lower a private loan payment, and it requires a credit check and proof of income—approval is not certain.
Estimating your payment before you borrow
If you're deciding how much to borrow, use the federal Repayment Estimator at studentaid.gov to see what different loan amounts would cost under different plans. Enter your expected income after graduation and the repayment plan you think you'll use. This shows you the monthly payment in real dollars, not an abstract percentage.
For private loans, the lender's website usually has a calculator where you enter the loan amount, interest rate, and term. This gives you an estimate of the monthly payment. Keep in mind that the interest rate shown is an estimate—your actual rate depends on your credit score and income at the time you apply.
A useful rule of thumb: on a standard 10-year federal plan, your monthly payment will be roughly 1% of your total loan balance per month (before interest is fully factored in). A $40,000 loan costs around $400 a month. This is not exact, but it's close enough to use as a starting point when deciding how much to borrow.
Frequently Asked Questions
What if I don't know which repayment plan I'm on?
Log into your servicer's website or call them—they'll tell you your current plan and show you what other plans would cost. If you haven't chosen a plan, federal loans default to the Standard Repayment Plan. You can change it at any time.
Can my payment go down if my income drops?
Only if you're on an income-driven plan. Standard, graduated, and extended plans have fixed payments regardless of income. If you're on an income-driven plan, your payment recalculates each year based on your income, so it can go down if you earn less. You must recertify your income annually to keep the plan active.
Why is my payment higher than I calculated?
Interest accrues daily on unsubsidized loans, so the balance grows between when you calculated it and when you started paying. If you had unsubsidized loans while in school, accrued interest was capitalized when repayment began, raising your balance. Also, some servicers round payments up to the nearest dollar.
Do I have to pay the full amount my servicer says I owe?
Yes, unless you're on an income-driven plan and your income is low enough to may have access to for a $0 payment. If you can't afford your current payment, contact your servicer about switching to an income-driven plan or requesting forbearance or deferment. Paying less than required without approval will put your loan in default.
What's the difference between what I owe and what I'll actually pay?
What you owe is your current balance plus accrued interest. What you'll pay is your monthly payment multiplied by the number of months until the loan is paid off. On a 10-year plan, you'll pay significantly more than your current balance because of interest. On an income-driven plan with forgiveness, you may pay less than the original balance if the loan is forgiven after 20 to 25 years.
