Formula Used for Ontario Loan Calculations
The calculator uses the standard mortgage payment formula:
Monthly Payment 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 Ontario mortgages, the calculator also accounts for:
- Ontario's property transfer tax (1% of purchase price)
- Municipal land transfer tax (varies by municipality)
- HST (13% on home prices over $500,000)
Worked Example
Let's calculate a $300,000 mortgage with a 5-year term and 4% annual interest rate.
Example Calculation
Monthly interest rate: 4% ÷ 12 = 0.333%
Number of payments: 5 × 12 = 60
Monthly payment: $300,000 [ 0.00333(1.00333)60 ] / [ (1.00333)60 - 1 ] ≈ $6,200.48
Total interest paid: ($6,200.48 × 60) - $300,000 ≈ $132,072.80
This example shows that a $300,000 mortgage with a 5-year term at 4% interest would cost approximately $6,200 per month with $132,073 in total interest.
