Calculating Payment for a Small Personal Loan
Finding the payment for a $5,000 loan at 9% interest over 24 months.
- Identify loan parameters: P = $5,000, Annual Rate = 9%, Term = 24 months.
- Convert to monthly values: r = 0.09 / 12 = 0.0075, n = 24.
- Apply the formula: $5,000 ร [0.0075(1+0.0075)^24] / [(1+0.0075)^24 - 1].
- Result: The monthly payment is $228.42.
