$40,000	5.80%	15 years	Biweekly	0 months	$25	$500	Smaller periodic cash flow with extra principal reduction
$12,500	4.20%	8 years	Monthly	3 months	$0	$0	Standard repayment without acceleration

Formula Used

1. Origination fee: Origination Fee = Loan Amount × Fee Rate

2. Principal before repayment: Beginning Principal = Loan Amount + Financed Fee

3. Deferment growth: Deferred Balance = Beginning Principal × (1 + APR ÷ 12)^Months

4. Periodic rate: Periodic Rate = APR ÷ Payments per Year

5. Scheduled payment: Payment = P × r ÷ [1 − (1 + r)⁻ⁿ]

6. Per-period split: Interest = Balance × Periodic Rate, Principal = Payment − Interest

7. Closing balance: Ending Balance = Opening Balance − Principal Paid

When the interest rate is zero, the calculator divides the balance evenly across all repayment periods.

FAQs

1. What does this calculator estimate?

It estimates education loan payments, interest, payoff timing, deferment effects, fee financing, and how extra payments change the full repayment path.

2. Why include deferment or grace period months?

Many study loans start repayment after school or after a short grace window. Including deferment helps you see how interest growth can affect future payments.

3. What is capitalization in this calculator?

Capitalization means accrued deferment interest gets added to the repayment balance. That increases the amount being amortized and usually raises total interest later.

4. What happens if I add extra payments?

Extra payments reduce principal faster. That usually shortens repayment length, lowers total interest, and can move your payoff date earlier than the base plan.

5. Is the origination fee always financed?

No. You can choose to finance the fee or pay it upfront. Financing raises the balance, while paying upfront increases immediate cost instead.

6. Can I use this for weekly or biweekly repayment?

Yes. The calculator supports quarterly, monthly, biweekly, and weekly schedules so you can compare how different repayment frequencies affect cash flow.

7. Does the calculator replace a lender disclosure?

No. It is a planning tool. Actual lender statements may differ because of servicing rules, variable rates, rounding conventions, or repayment program changes.

8. When should I export CSV or PDF?

Export when you want to save scenarios, compare repayment plans, share estimates with family, or keep a printable record for budgeting discussions.
