Why a 15-Year Mortgage Plan is Popular

A 15-year mortgage is often preferred by borrowers who want:

Understanding the Mortgage Formula

The calculator uses the standard amortization formula used by banks worldwide.

Monthly Mortgage Payment Formula:

M=Pr(1+r)n(1+r)n1M = \frac{P \cdot r \cdot (1+r)^n}{(1+r)^n - 1}M=(1+r)n−1P⋅r⋅(1+r)n​

Where:

  • M = Monthly payment
  • P = Loan amount (principal)
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Total number of payments (years × 12)

What This Formula Means

This formula ensures your loan is repaid in equal monthly installments over 15 years. Each payment includes:

  • Interest portion (bank’s profit)
  • Principal portion (loan repayment)

At the start, interest is higher, and over time, principal repayment increases.


Example Calculation

Let’s understand this with a real-life example:

Loan Details:

  • Loan Amount = $200,000
  • Interest Rate = 6% per year
  • Loan Term = 15 years

Step 1: Convert values

  • Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
  • Total months = 15 × 12 = 180

Step 2: Apply formula

Monthly payment ≈ $1,687.71

Step 3: Calculate totals

  • Total payment = $303,787.80
  • Total interest = $103,787.80

Final Result:

A $200,000 loan at 6% interest for 15 years will cost:

  • 💰 Monthly Payment: ~$1,687
  • 💰 Total Interest: ~$103,787
