How We Calculated This
The fixed monthly payment for any installment loan uses this formula: M = P [r(1+r)^n] / [(1+r)^n - 1]. Where P = principal ($20,000), r = monthly interest rate (8%/12 = 0.006667), and n = total payments (60). Plugging in: M = 20000 x 0.0202765 = $405.53. Use our loan calculator to do this math instantly.
