Calculation Logic

The Pre Approval Home Loan Calculator estimates loan eligibility using:

1. Debt-to-Income (DTI) Ratio:

$$\text{DTI} = \frac{\text{Monthly Debts} + \text{Proposed Mortgage Payment}}{\text{Monthly Gross Income}}$$DTI=Monthly Gross IncomeMonthly Debts+Proposed Mortgage Payment​

Lenders typically prefer DTI ≤ 36–43%.

2. Monthly Mortgage Payment:

$$\text{Payment} = P \times \frac{r(1+r)^n}{(1+r)^n-1}$$Payment=P×(1+r)n−1r(1+r)n​

Where:

• $P$P = loan principal
• $r$r = monthly interest rate
• $n$n = total number of payments

3. Loan Amount Estimate:

$$\text{Loan Amount} = \text{Maximum Affordable Payment} \div \text{Mortgage Factor (from interest and term)}$$Loan Amount=Maximum Affordable Payment÷Mortgage Factor (from interest and term)

Practical Example

Suppose:

• Gross annual income: $80,000
• Monthly debts: $500
• Expected interest rate: 5%
• Loan term: 30 years
• Down payment: $20,000

Step 1: Calculate Max Affordable Mortgage Payment

Assume DTI max 36%:$$\text{Max Payment} = \frac{36\% \times 6,667 - 500}{1} = 1,900 \text{ USD/month}$$Max Payment=136%×6,667−500​=1,900 USD/month

(6,667 = 80,000 ÷ 12)

Step 2: Estimate Loan Amount

Using mortgage formula, $1,900/month payment at 5% for 30 years ≈ $355,000 loan

Step 3: Add Down Payment

$$355,000 + 20,000 = 375,000$$355,000+20,000=375,000

You could be pre-approved for a home up to $375,000.
