The monthly payment uses the standard amortizing loan formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1], where P is the $15,000 principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (years × 12). Each payment covers the interest accrued that month first, with the remainder reducing the principal — so early payments are mostly interest and later payments are mostly principal.
