Compare blended balances, rates, terms, and costs. Estimate lower payments, total interest, and payoff timing. Plan smarter borrowing decisions with clearer repayment projections today.
Enter each loan separately. Rates should be entered without the percent sign.
| Loan | Example Balance | Example APR | Example Remaining Months |
|---|---|---|---|
| Loan 1 | $12,000.00 | 4.800% | 96 |
| Loan 2 | $9,500.00 | 5.200% | 108 |
| Loan 3 | $6,200.00 | 6.000% | 84 |
| Loan 4 | $3,800.00 | 5.750% | 72 |
Try these values, then test different terms, fees, and extra payments to compare how monthly cash flow and long term repayment costs change.
Weighted average rate
Weighted Rate = Sum of (Loan Balance × Loan Rate) ÷ Sum of Loan Balances
Federal rounded rate
Federal Rounded Rate = Ceiling(Weighted Rate × 8) ÷ 8
Starting consolidated balance
Starting Balance = Total Loan Balance + Fees + Capitalized Interest + Grace Period Interest
Grace period interest
Grace Interest = Balance Before Grace × Monthly Rate × Grace Months
Monthly payment
Payment = P × r ÷ (1 - (1 + r)-n)
Total interest
Total Interest = Total Paid - Starting Principal
Student loan consolidation can simplify repayment. It combines several education debts into one new loan. One bill is easier to track. One due date can reduce missed payments. This calculator measures the tradeoff. It compares your current loan mix with a new consolidated scenario. You can test weighted rates, federal style rounded rates, fees, unpaid interest, and longer terms. That gives a clearer view of repayment before you submit any application.
Many borrowers focus only on the new monthly payment. That can be misleading. A lower payment often comes from extending the term. More months can mean more interest. This calculator shows both sides together. It estimates your current combined payment, the projected new payment, and the total remaining interest in each path. That comparison is useful for budgeting, debt planning, and cash flow decisions during school, residency, or early career stages.
Not every consolidation uses the same interest method. Some estimates rely on a simple weighted average. Federal Direct Consolidation commonly rounds the weighted average up to the nearest one eighth of one percent. Even a small rate change can affect total cost over a long term. This calculator lets you compare both methods. It also lets you enter a custom APR if you want to model a refinance style offer or another lender estimate.
Borrowers often forget the effect of added costs. Origination fees, capitalized unpaid interest, and grace period interest can increase the starting balance. A higher opening balance raises the new payment or lengthens repayment. Extra monthly payments can reverse that effect. They often cut payoff time and reduce total interest. This calculator includes those inputs so you can test realistic scenarios. Use it to compare repayment plans, build a stronger higher education budget, and choose a strategy with fewer surprises.
It means combining multiple student loans into one new loan. You get one balance, one payment, and one repayment term. It can simplify tracking, but it does not always reduce total borrowing cost.
Not always. Some programs use a weighted average of current rates, and some federal calculations round upward. Your payment may fall because of a longer term, even when the rate stays similar.
A longer repayment term spreads the balance over more months. That lowers the required payment. However, interest accrues for a longer period, so total repayment can increase.
It is a common federal consolidation rule. The weighted average rate is rounded up to the nearest 0.125%. That small adjustment can slightly raise the projected interest cost.
Yes. Added fees and capitalized interest increase the new starting balance. If you leave them out, the estimate may look better than the real repayment offer.
Extra payment usually shortens payoff time and cuts interest. Even small added amounts each month can make a meaningful difference over long student loan repayment periods.
No. Consolidation often combines loans under one structure. Refinancing usually replaces old loans with a new private loan and can change both rate and borrower protections.
No. It is an estimate tool for planning. Always compare the results with official lender terms, program rules, repayment notices, and any forgiveness or deferment conditions.
