Formula Explanation (How It Works)
This calculator is based on widely accepted financial planning formulas.
1. Maximum Housing Budget Formula
MaxHousingBudget=MonthlyIncome×HousingPercentage
If:
- Income = $5,000
- Housing Percentage = 28%
Then:
- $5,000 × 28% = $1,400
This means you should ideally spend no more than $1,400/month on housing.
2. Remaining Monthly Budget
RemainingBudget=Income−Debts−Expenses
This shows how much money you have left after all obligations.
3. Debt-to-Income Ratio (DTI)
DTI=(MonthlyDebt÷MonthlyIncome)×100
This is one of the most important financial indicators used by lenders.
Understanding Debt-to-Income Ratio (DTI)
Your DTI ratio shows how much of your income goes toward debt payments.
DTI Categories:
- Below 20% → Excellent
- 20% – 35% → Good
- 35% – 50% → Risky
- Above 50% → Critical
A lower DTI means better financial health and higher loan approval chances.
Example Calculation
Let’s take a real-life example:
- Monthly Income: $6,000
- Monthly Debts: $1,200
- Monthly Expenses: $2,000
- Housing Percentage: 28%
Step 1: Max Housing Budget
$6,000 × 28% = $1,680
Step 2: Remaining Budget
$6,000 - $1,200 - $2,000 = $2,800
Step 3: DTI Ratio
($1,200 ÷ $6,000) × 100 = 20%
Final Result:
- Max Housing Budget: $1,680
- Remaining Budget: $2,800
- DTI: 20% (Good)
- Financial Status: Good

| $5,000 | $1,000 | $1,500 | $1,400 | $2,500 | Good |
| $6,000 | $1,200 | $2,000 | $1,680 | $2,800 | Excellent |
