True loan cost = monthly × term + all fees - principal. Reveals premium paid for borrowing. 15k loan with 400 fees: total 19k = 4k cost of borrowing.
A worked example
Try the defaults: loan amount of 15,000, monthly payment of 304, term months of 60, all fees of 400. The tool returns 3,640.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Loan Amount, Monthly Payment, Term Months, and All Fees. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
The formula behind this
Total payments + fees - original loan = cost of borrowing. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Reading the output honestly
The payoff date assumes every payment lands on time and at the amount you entered. In reality, months with unexpected expenses happen. Treat the figure as the best-case timeline and add a buffer for life if you want a realistic target.
What this doesn't capture
Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.
What to calculate alongside this
One figure by itself is fragile. The loan repayment schedule calculator, the apr calculator, and the true cost of debt calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.
