Example of Credit Installment Calculator
Let’s calculate the monthly installment for a loan with the following details:
- Principal (P): $20,000
- Annual Interest Rate: 6%
- Loan Term: 48 months
- Convert the annual interest rate to a monthly rate: r = 6% / 12 = 0.005 (or 0.5%)
- Substitute the values into the formula:Installment = (20,000 × 0.005 × (1 + 0.005)^48) / ((1 + 0.005)^48 - 1)
- Calculate: Installment = (100 × 1.28368) / (1.28368 - 1) Installment = 128.368 / 0.28368 Installment ≈ 452.72
The monthly installment for this loan is approximately $452.72.
