A planning estimate; real values depend on contracts, rates, taxes and each case's conditions.
The financing simulator works out the monthly payment, total paid and total interest of a loan or financing with fixed installments, using the Price table. It suits anyone comparing car, home or personal loan offers who wants to see how much interest weighs on the final cost.
You enter the loan amount, the annual interest rate and the term in months. The annual rate is treated as effective and converted to an equivalent monthly rate. The payment follows the Price table formula: PMT = P × [i(1+i)^n] / [(1+i)^n − 1], giving a constant installment. The tool tracks the balance month by month and shows, per year, how much went to principal, how much to interest and the remaining balance.
A loan of $30,000 at 24% a year over 36 months. The equivalent monthly rate is about 1.81%, and the payment comes to roughly $1,141.14. Total paid is about $41,081, meaning $11,081 of interest on the $30,000 borrowed. Longer terms lower the payment but increase the interest.
This is an illustrative simulation, not a credit offer. Fees, insurance, taxes and other charges are not included, and real terms vary by lender and credit profile. Ask the lender for an official quote.
