Formula Used in the Calculator
1. Monthly Income:
Monthly Income = Annual Income ÷ 12
2. Maximum Monthly Payment:
Max Payment = (Monthly Income × 0.28) − Monthly Debts
(28% rule is a common lending guideline)
3. Loan Amount Formula:
If interest rate > 0:
Loan = P × [(1 − (1 + r)^−n) ÷ r]
Where:
- P = Monthly payment
- r = Monthly interest rate
- n = Total number of payments
4. Debt-to-Income Ratio (DTI):
DTI = (Total Monthly Debt ÷ Monthly Income) × 100
Example Calculation
Example 1:
- Annual Income: $60,000
- Monthly Debts: $500
- Down Payment: $20,000
- Interest Rate: 6.5%
- Loan Term: 30 years
Results:
- Monthly Income = $5,000
- Max Payment ≈ $900
- Estimated Loan Amount ≈ $140,000
- Max Home Price ≈ $160,000
