How the Excel Loan Calculator Works

The calculator uses the standard loan amortization formula to determine monthly payments and total costs.

Inputs Required:

• Loan amount (principal)
• Interest rate (annual, % APR)
• Loan term (in months or years)
• Down payment (optional)

Outputs Users Expect:

• Monthly payment
• Total interest paid over the loan term
• Total repayment amount
• Optional amortization breakdown

Formula Used

The monthly payment formula:$$M = P \frac{r(1+r)^n}{(1+r)^n - 1}$$M=P(1+r)n−1r(1+r)n​

Where:

• $M$M = monthly payment
• $P$P = loan principal (after down payment)
• $r$r = monthly interest rate (annual rate ÷ 12 ÷ 100)
• $n$n = total number of monthly payments

Total interest = $M \times n - P$M×n−P
Total repayment = $P + \text{Total Interest}$P+Total Interest

Practical Example

Example:

• Loan amount = $15,000
• Down payment = $2,000
• Interest rate = 5% APR
• Loan term = 3 years (36 months)

Calculation:

Loan principal = 15,000 – 2,000 = 13,000
Monthly interest rate = 5 ÷ 12 ÷ 100 ≈ 0.004167

Monthly payment:$$M = 13000 \frac{0.004167(1+0.004167)^{36}}{(1+0.004167)^{36}-1} \approx 389.40$$M=13000(1+0.004167)36−10.004167(1+0.004167)36​≈389.40

Total interest = 389.40 × 36 – 13,000 ≈ $1,020.40
Total repayment = 13,000 + 1,020.40 ≈ $14,020.40
