✅ Currency Symbol Included – The currency you selected will be displayed alongside the amount.

3️⃣ Understanding the Calculation Results

Once the calculations are complete, the result will be displayed in this format:

🔹 Estimated Monthly Payment: $2,200.50

This amount represents the fixed monthly payment you will need to make for the duration of the loan term.

✔ How the Monthly Payment is Calculated

1️⃣ Monthly Interest Rate

• The calculator converts the annual interest rate into a monthly interest rate by dividing it by 12.

2️⃣ Loan Payment Formula

• The formula used to calculate the monthly payment is:

M=P×r1−(1+r)−nM = \frac{P \times r}{1 – (1 + r)^{-n}}

Where:

• M = Monthly Payment
• P = Loan Amount (Principal)
• r = Monthly Interest Rate (Annual Rate ÷ 12)
• n = Loan Term in Months

3️⃣ Final Computation

• The calculator applies this formula automatically and provides the monthly payment result in seconds.

4️⃣ Example Calculation

Let’s assume a loan with the following details:

✔ Currency = USD ($)
✔ Loan Amount = $50,000
✔ Annual Interest Rate = 6%
✔ Loan Term = 24 months

Step-by-Step Breakdown

1️⃣ Convert the annual interest rate into a monthly rate:

• 6% per year = 0.06 ÷ 12 = 0.005 (0.5% per month)

2️⃣ Apply the loan payment formula:

• Monthly Payment = (50,000 × 0.005) ÷ (1 – (1 + 0.005)^-24)
• = (250) ÷ (1 – (1.005)^-24)
• = (250) ÷ (1 – 0.886)
• = (250) ÷ (0.114)
• = $2,193.70 per month

Final Result: “Estimated Monthly Payment: $2,193.70”
