Formula Explained

The calculator uses the standard mortgage payment formula with adjustments for cost of living:

Mortgage Payment Formula:

P = L × [r(1 + r)ⁿ] / [(1 + r)ⁿ - 1]

Where:

P = Monthly payment
L = Loan amount (Home Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12 / 100)
n = Number of payments (Loan Term × 12)

The cost of living adjustment is applied annually to the loan amount and recalculated each year.

Worked Example

Let's calculate a mortgage payment with these inputs:

Home Price: $300,000
Down Payment: 20% ($60,000)
Loan Term: 30 years
Interest Rate: 4.5%
Annual Cost of Living Increase: 2%

The initial monthly payment would be approximately $1,384. The payment after one year of 2% cost of living increase would be about $1,412, showing the impact of inflation on your mortgage.
