📖 Overview
Use this calculator to benchmark housing affordability against income.
🧪 Example Scenarios
Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.
| Input | Base Case | Higher Pressure Case |
|---|---|---|
| Monthly Rent ($) | 1,800 | 2,070 |
| Gross Monthly Income ($) | 6,000 | 5,400 |
⚙️ How It Works
This calculates housing burden by dividing monthly rent by gross monthly income and expressing it as a percentage.
The Formula
Rent-to-Income % = (Monthly Rent ÷ Gross Monthly Income) × 100
| Rent | Total monthly rent payment |
| Income | Gross monthly income before taxes |
💡The classic "30% rule" means keeping rent below 30% of gross income. In high-cost cities many people exceed this — pair with a full budget review to assess real impact.
Quick Reference
| Ratio | Housing Burden | Typical Guideline |
|---|---|---|
| < 25% | Low | Plenty of room for savings and other expenses |
| 25–30% | Moderate | Widely accepted affordability threshold |
| 30–40% | High | Many lenders flag as cost-burdened |
| > 40% | Very High | Severe housing burden; financial stress risk |
When To Use This
- Use this tool when you need a fast decision during active planning or execution.
- Use this before committing money, time, or tradeoffs that are hard to reverse.

Edge Cases To Watch
- Results can be misleading if key inputs are missing, stale, or unrealistic.
- Very small or very large values may amplify rounding effects and interpretation risk.
- If assumptions change mid-decision, recalculate before acting.
Practical Tips
💡 Use this to compare rental options objectively.
