Mortgage Formula

The monthly mortgage payment is calculated using the standard mortgage formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

For a 15-year loan at 2.5% interest, the monthly interest rate is 0.25% (2.5% ÷ 12) or 0.002083 in decimal form.

Worked Example

Let's calculate a $200,000 mortgage with these parameters:

Loan amount: $200,000
Interest rate: 2.5% (0.025)
Loan term: 15 years (180 months)

Using the formula:

i = 0.025 ÷ 12 = 0.002083

n = 15 × 12 = 180

M = 200,000 [ 0.002083(1 + 0.002083)^180 ] / [ (1 + 0.002083)^180 - 1 ]

M = $1,226.36 per month

Over 15 years, you would pay $222,744.80 in total, with $22,744.80 going to interest.

Loan Comparison

Here's how a $200,000 mortgage compares at different interest rates and terms:

Interest Rate	15-Year Payment	30-Year Payment	Total Interest
2.5%	$1,226.36	$742.04	$22,744.80
3.0%	$1,258.59	$775.74	$25,186.80
3.5%	$1,291.38	$810.77	$27,660.80

Note: These are simplified examples. Actual payments may vary based on additional fees and closing costs.
