| Metric | Value | Meaning |
|---|---|---|
| Loan amount | $25,000 | Principal before fees and optional products |
| Monthly payment | $501 | Estimated principal and interest |
| Total interest | $5,057 | Interest over the full term |
| Total repaid | $30,057 | Principal plus interest |
| Interest share of payments | 16.82% | Interest divided by total repaid |
Formula and Method
| Item | Formula | Use |
|---|---|---|
| Monthly payment | M = P x [r(1+r)^n] / [(1+r)^n - 1] | Fixed-rate amortized loan estimate |
| Monthly rate | annual rate / 12 | Converts annual rate into a monthly rate |
| Number of payments | loan term in years x 12 | Sets the amortization length |
| Total interest | (monthly payment x n) - principal | Shows borrowing cost before fees |
The payment formula assumes a fixed rate and equal monthly payments. It does not automatically add origination fees, taxes, insurance, late charges, or optional products.
Term Comparison
| Term | Monthly payment | Total interest | Total repaid |
|---|---|---|---|
| 3 years | $778 | $2,996 | $27,996 |
| 5 years | $501 | $5,057 | $30,057 |
| 7 years | $383 | $7,210 | $32,210 |
Worked example: borrowing $25,000 at 7.50% for 60 months creates an estimated payment of $501 and about $5,057 in interest before fees.
How to Use the Result
Use the monthly payment to test cash flow, then use total interest to test whether the term is too expensive.
When comparing real offers, compare APR, amount financed, loan term, monthly payment, total of payments, fees, and prepayment terms together.
A lower monthly payment can be useful, but it is not automatically the cheaper loan if the repayment period is longer.

FAQ
What does a simple loan calculator show?
A simple loan calculator estimates the monthly principal-and-interest payment, total interest, and total amount repaid for a fixed-rate installment loan.
How do you calculate a fixed-rate loan payment?
Most fixed-rate loan calculators use the amortization formula M = P x [r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is the monthly interest rate, and n is the number of monthly payments.
Why is the total interest higher on longer loan terms?
A longer term usually lowers the monthly payment but keeps the balance outstanding for more months. That can increase total interest even when the interest rate and loan amount stay the same.
What happens if the interest rate is zero?
With a zero-interest loan, the payment is principal divided by total months because there is no financing charge to amortize.
Is this the same as APR?
Not exactly. APR can include interest plus certain fees and borrowing costs. This calculator uses the rate you enter, so compare lender offers by APR when fees differ.
Is this calculator a loan approval or quote?
No. It is an educational estimate. A real loan quote can differ because of APR, fees, credit history, collateral, repayment timing, taxes, insurance, optional products, and lender underwriting.
