Use the slider controls to instantly change your monthly payment, loan amount, interest rate or term.
How the enhanced loan calculator works
It amortizes your loan including any extra monthly payments, then adds an origination fee to show the all-in cost. Because the fee is taken from the amount you receive, it makes the loan cost more than the headline rate suggests.
Worked example: with loan amount of $30,000, monthly payment of $600 and interest rate of 7.50%, the enhanced loan calculator shows monthly payment of $601.14.
- Loan amount
- $30,000
- Principal & interest
- $601.14
- Total interest
- $6,068
- Origination fee
- $600
The formula
Payment = P × r ÷ (1 − (1 + r)⁻ⁿ), reduced by extra payments. Total cost = total of payments + origination fee; cash received = amount − fee.

Questions about the enhanced loan calculator
How do origination fees affect a loan?
A fee is deducted from the money you receive but you still repay the full amount, so your true cost is higher than the stated rate. Always compare loans on all-in cost.
Should I make extra payments?
If there is no prepayment penalty, yes — extra principal shortens the term and cuts interest. The calculator shows the effect of any extra amount.
Is a low rate with a high fee a good deal?
Not always. A slightly higher rate with no fee can cost less overall, especially on shorter loans. Compare the total cost figure, not just the rate.
Is the Enhanced Loan Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
