About the loan calculator
What the loan calculator tells you.
Enter the amount you want to borrow, the APR a lender quotes, and the months you would take to repay, and this calculator returns the fixed monthly payment, the total interest, and the full cost once the last payment clears. The math is standard amortization, the same formula every lender uses.
It earns its keep when you run a few versions. A shorter term raises the monthly payment but cuts the total interest, and a lower rate barely moves the monthly while trimming the lifetime cost. Treat the result as a close estimate, not a quote: your real APR depends on your credit and the lender, and fees can push the true cost higher.
