Student Loan Consolidation Calculator
If you have multiple federal student loans, consolidation combines them into a single Direct Consolidation Loan with one monthly payment. The new interest rate is the weighted average of your current rates, rounded up to the nearest one-eighth percent. Use the student loan calculator above to estimate your consolidated monthly payment — enter your combined balance and the blended rate.
Consolidation is different from refinancing. Consolidation keeps your loans federal (preserving IBR, SAVE, and forgiveness options). Refinancing with a private lender like SoFi or Earnest can get you a lower rate but removes federal protections. Our student loan consolidation calculator approach: enter total balance + weighted average rate to see your payment instantly.
Private Student Loan Rates — Discover, SoFi & Others
If you're comparing private lenders, our tool works as a SoFi loan estimator, a Discover student loan calculator, or any private lender calculator — just enter the rate you've been quoted and your loan amount. For the 2024-25 academic year, private student loan interest rates typically range from 4% to 15% depending on your credit score, income, and lender.
Popular private lenders and their typical rate ranges in 2025: SoFi — from 4.99% fixed · Discover student loan — from 5.24% fixed · Earnest — from 4.45% fixed · Sallie Mae — from 4.50% fixed · Citizens Bank — from 5.25% fixed. Rates vary by credit profile — always get a personalised quote before applying.
Student Loan APR Calculator — What Is APR?
APR (Annual Percentage Rate) includes both the interest rate and any loan fees, expressed as a yearly rate. For most federal student loans there are no origination fees beyond the standard ones, so the APR is close to the stated interest rate. For private loans, origination fees can make the APR noticeably higher than the advertised rate. To use this as a student loan APR calculator: simply enter the APR instead of the interest rate in the rate field above — the monthly payment and total cost calculation works identically.

Student Loan Repayment Plans — USA Comparison
Federal student loans offer multiple repayment plans. The right plan depends on your income, loan balance, and financial goals. Here is a quick comparison of the main USA student loan repayment options:
| Plan | Payment Based On | Term | Best For |
| Standard | Fixed amount | 10 years | Paying least interest |
| Graduated | Starts low, increases | 10 years | Expecting income growth |
| Extended | Fixed or graduated | 25 years | Large balances (>$30K) |

| SAVE | 5-10% of discretionary income | 20-25 years | Lowest income-driven payment |
How to Pay Off Student Loans Faster
Use our student loan payoff calculator to see the impact of making extra payments. Even small amounts make a significant difference over time due to compound interest. Here are the most effective strategies:
- Make extra payments toward principal — every extra dollar reduces the balance interest is calculated on.
- Refinance to a lower rate — if your credit has improved, you may qualify for a lower interest rate on private loans.
- Apply windfalls directly to the loan — tax refunds, bonuses, and gifts applied to principal dramatically reduce payoff time.
- Choose the standard 10-year plan over extended plans — longer terms mean lower monthly payments but far more interest paid overall.
- Avoid deferment when possible — on unsubsidized loans, interest accrues during deferment and capitalizes when repayment resumes.
Student Loan Debt Calculator — Know Your Total Debt Cost
Our student loan debt calculator shows you the complete picture — not just your monthly payment but your total debt cost including every dollar of interest over the life of the loan. Many borrowers focus only on the monthly number and miss the bigger picture. A $35,000 loan at 6.53% over 10 years costs $12,750 in interest alone — money that goes straight to the lender, not your education.
Use the amortization schedule in this student loan calculator to see a year-by-year breakdown of exactly how much goes to principal versus interest each year. In the early years of repayment, most of your payment goes toward interest — this is why extra payments in the first few years have the biggest impact on total cost.
Student Loan Amortization Schedule & Table
The student loan amortization schedule in this calculator shows every year of your repayment — how much of each payment goes to interest, how much reduces your principal, and what your remaining balance is. This student loan amortization table is especially useful when comparing different loan terms. Switching from a 10-year to a 7-year term increases your monthly payment but drastically cuts the total interest paid — the amortization table makes this visible at a glance.
Income-Driven Repayment Plan Calculator
This income-driven repayment plan calculator covers both IBR (Income-Based Repayment) and the newer SAVE plan. IBR caps your payment at 10% of discretionary income — the amount above 150% of the federal poverty line for your family size. The SAVE plan (Saving on a Valuable Education) is the newest income-driven repayment plan, introduced in 2023, and uses 5% of discretionary income above 225% of the poverty line — making it the lowest payment option for most borrowers with undergraduate debt.
To use the income-driven repayment plan calculator, select "IBR" or "SAVE Plan" from the loan type dropdown and enter your annual income and family size. The calculator shows your monthly payment under each plan instantly.
Average Student Loan Interest Rate — 2025
The average student loan interest rate depends on the loan type. Federal loans have fixed rates set annually by Congress. For 2024-2025 the average federal undergraduate rate is 6.53%. Private student loan interest rates vary widely — the average interest rate for private student loans ranges from 4% for borrowers with excellent credit to over 14% for those with limited credit history. If your private loan rate is above 8%, refinancing is worth exploring. Use the refinance tab in this calculator to see your potential savings.
Private Student Loan Rates — Discover, SoFi & Others
Private student loan interest rates in 2025 range from approximately 4% to 15% APR depending on your lender, credit score, and whether you choose a fixed or variable rate. Major lenders include SoFi, Discover Student Loans, Sallie Mae, College Ave, and Citizens Bank. Unlike federal loans, private student loan rates are not standardised — always compare at least three lenders before borrowing. Use this private student loan calculator to see exactly how rate differences affect your total cost over the life of the loan.
Student Loan APR Calculator — What Is APR?
APR (Annual Percentage Rate) on a student loan includes the interest rate plus any fees charged by the lender — origination fees, disbursement fees, and so on. For federal student loans, the APR equals the interest rate because federal loans have no origination fees for undergraduates (PLUS loans do have a 4.228% fee). For private student loans, the APR may be higher than the stated interest rate if the lender charges fees. Always compare APR — not just the interest rate — when shopping for private loans.
Student Loan Consolidation Calculator
Federal student loan consolidation combines multiple federal loans into one Direct Consolidation Loan with a single monthly payment. The new interest rate is the weighted average of your existing rates rounded up to the nearest 0.125%. Consolidation can simplify repayment and may extend your term to up to 30 years — lowering your monthly payment but increasing total interest. This calculator handles single-loan scenarios. For multi-loan consolidation, calculate the weighted average rate first, then use that as your interest rate input.
This student loan calculator is for educational and planning purposes only. Interest rates and repayment terms may change. Always verify current rates with your loan servicer or the Federal Student Aid website (studentaid.gov) before making financial decisions.
