Student Loan Payoff Calculator
Add your student loans, set an extra monthly payment, and see exactly how much interest your degree is really costing you. Compares standard repayment against aggressive payoff so you can see the difference in dollars and months.
Your student loans
Unburden tracks the full story.
Student loans do not exist in a vacuum. Most borrowers carry car payments, credit cards, and other obligations alongside their education debt. This calculator sees one chapter. The app reads the whole book.

Student debt affects more than your wallet. Your Burden Score captures the full pressure.
Your credit score tells lenders how valuable you are to them. Your Burden Score tells you how vulnerable you are to yourself. It measures five proprietary stress signals across all your debts, not one loan type in isolation. A 750 credit score and a Critical Burden Score can exist on the same person. Find yours free in about 60 seconds.
Your student loans do not have to define your financial life.
The real cost of student loan debt
The sticker price of your degree told one story. The total cost of repayment tells a different one. Between origination fees, compounding interest, and a repayment timeline that stretches across decades, the gap between what you borrowed and what you will actually pay can be substantial. This calculator exists to make that gap visible before it compounds further.
How student loan interest works
Student loan interest accrues daily, not monthly. Your servicer calculates a daily interest charge using the formula: (outstanding principal x annual rate) / 365.25. That daily charge gets added to your accrued interest balance every single day, whether or not you are making payments.
This matters most during deferment and forbearance. On unsubsidized loans, interest keeps accruing while payments are paused. When the pause ends, that unpaid interest capitalizes. It gets folded into your principal, and you begin paying interest on interest. A $35,000 loan at 6.5% that sits in deferment for 18 months adds roughly $3,400 in capitalized interest. You now owe $38,400 and the interest clock resets on the higher balance.
Even during active repayment, daily accrual means that making your payment earlier in the month costs you less interest than paying on the last day. The difference is small on any individual month, but over a 10-year standard repayment plan, it adds up.
Standard vs aggressive repayment
Standard repayment is the default plan for most federal student loans: fixed payments over 10 years. It is predictable and it works, but it also means you are paying interest for the full decade. The total interest bill on a $35,000 loan at 6% over 10 years is roughly $11,600. You borrowed $35,000 and paid back nearly $47,000.
Aggressive repayment means putting extra money toward your loans each month. Even modest increases make an outsized difference because every dollar of extra payment goes directly to principal. It skips the interest calculation entirely. An extra $150 per month on that same $35,000 loan cuts the repayment period by roughly 3 years and saves thousands in interest.
The calculator above runs both scenarios side by side so you can see the exact dollar impact for your specific loans.
The snowball vs avalanche debate for student loans
When you have multiple student loans, the order in which you attack them matters. The snowball method targets the smallest balance first, giving you a quick win when that first loan hits zero. The avalanche method targets the highest interest rate first, minimizing total interest paid.
For student loans specifically, the interest rate spread often determines which approach makes more sense. If your loans are all within a percent or two of each other, the interest savings from avalanche are minimal and the motivational boost of snowball may be worth more. If you have a mix of 3% subsidized and 7% unsubsidized loans, avalanche can save meaningful money by eliminating the expensive debt first.
The honest answer is that the method you stick with is the one that works. Research shows that motivation matters more than mathematical optimality for long-term debt payoff.
There is a third option. Unburden's Momentum strategy is mathematically constrained to match or beat Avalanche on total interest while giving you the quick wins of Snowball. It dynamically adapts to your specific debt profile. Only available in the app.
Student loans and your financial health
Student loan debt does not exist in isolation. It affects your debt-to-income ratio, which determines whether you qualify for a mortgage, a car loan, or a line of credit. A DTI above 36% starts to limit your options. Above 43%, most conventional mortgage lenders will not approve you.
Beyond the numbers, student debt delays life milestones. Research consistently shows that borrowers with significant student debt postpone homeownership, delay starting families, and are less likely to start businesses or contribute to retirement accounts in their twenties and thirties. The financial pressure extends far beyond the monthly payment amount.
This is why a payoff calculator alone is not enough. Knowing when you will be debt-free is valuable. Understanding how your total debt load is affecting your financial vulnerability right now is what actually drives better decisions.
Student debt is often the start, not the whole story. Most people carry car loans, credit cards, and other obligations alongside their education debt. Unburden tracks everything in one place, gives you a Burden Score that captures the full pressure, and updates as your balances change. Free to start, and your data never leaves your device.
Common questions
Disclaimer: Unburden is a planning tool, not a financial advisor. The calculations above are estimates based on the information you provide and assume consistent monthly payments at fixed interest rates. Actual results will vary based on individual circumstances, rate changes, payment behavior, and servicer-specific policies. This calculator uses monthly compounding for estimates; actual student loan interest accrues daily, which may cause minor differences. The Burden Score is an educational estimate, not financial advice. If you are struggling with debt, consider speaking with a Licensed Insolvency Trustee or a student loan counselor.
