How the Affordability Calculation Works
This calculator uses standard mortgage affordability rules used by lenders and financial institutions.
Step 1: Monthly Income Calculation
MonthlyIncome=AnnualIncome÷12
Step 2: Housing Expense Rule (28% Rule)
Lenders typically allow around 28% of monthly income for housing expenses.MaxHousingBudget=MonthlyIncome×0.28
Step 3: Subtract Existing Debt
AvailableMortgagePayment=MaxHousingBudget−MonthlyDebt
This gives the maximum monthly amount you can afford for a mortgage.
Mortgage Loan Formula Used
The tool calculates loan eligibility using the standard amortization formula:Loan=P×r1−(1+r)−n
Where:
- P = Monthly affordable payment
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Final Home Affordability Formula
MaximumHomePrice=LoanAmount+DownPayment
This gives the total home value you can realistically afford.
Example Calculation (Real-Life Scenario)
Let’s assume:
- Annual Income: $80,000
- Monthly Debt: $300
- Down Payment: $20,000
- Interest Rate: 6%
- Loan Term: 30 years
Step-by-step breakdown:
Monthly Income:
$80,000 ÷ 12 = $6,667
Housing Budget (28% Rule):
$6,667 × 0.28 = $1,867
Available for Mortgage:
$1,867 – $300 = $1,567
Loan Calculation:
Using mortgage formula:
- Loan Amount ≈ $260,000
- Down Payment = $20,000
Final Results:
- Maximum Home Price: $280,000
- Monthly Mortgage: $1,567
- Loan Amount: $260,000
