Rent Calculator
Find out how much rent you can afford based on your income and the 30% rule.
| Income % | Max Rent | + Utilities | Remaining |

Work out how much rent fits your budget using the standard 30%-of-income guideline, adjusted for your existing debt payments and estimated monthly utilities.
How Rent Calculator Works
The calculator multiplies your monthly gross income by your chosen rent ratio (30% by default, though you can adjust it) to get the "recommended max rent." It separately calculates an "affordable rent" figure that subtracts your existing monthly debt payments from that same budget, giving a more conservative number for anyone already carrying loan or credit card payments.
Total housing cost adds your monthly utilities estimate on top of the recommended rent, and the rent-to-income ratio is recalculated as (max rent ÷ income) × 100 to flag your situation: 30% or under is labeled "Affordable," 30–40% is "Moderate," and above 40% is flagged "Cost-Burdened," following the common income-based affordability bands used in housing research.
A comparison table below the result shows what your budget would look like at 25%, 30%, 35%, and 40% of income side by side, so you can see how much cushion — or how little — you'd have left after rent, debt, and utilities at each threshold.

Who Uses Rent Calculator and Why
- Finding a recommended maximum rent based on the standard 30%-of-income guideline for your actual gross income.
- Getting a more conservative affordable-rent figure once existing debt payments are factored in.
- Checking whether your current or prospective rent-to-income ratio falls into the Affordable, Moderate, or Cost-Burdened band.
- Comparing what your budget looks like at several rent-to-income thresholds (25%, 30%, 35%, 40%) side by side.
Mistakes to Avoid
- Confusing "recommended max rent" with "affordable rent after debts" — the first is purely income × the rent ratio, while the second subtracts your existing monthly debt payments, so relying on the wrong one can overstate what you can actually afford.
- Assuming the recommended max rent figure already includes utilities — it doesn't; utilities are added separately afterward to produce the total housing cost figure.
- Treating the 30% guideline as a hard rule rather than a general benchmark — it comes from long-standing housing affordability research but doesn't account for local cost of living or personal circumstances.
Tips for Best Results
- If you're already carrying debt payments, use the "affordable rent after debts" figure rather than the plain recommended max rent for a more realistic budget.
- Check the comparison table across 25-40% thresholds to see how much monthly cushion you'd have left at each level before committing to a specific rent.
Fixing Common Problems
My total housing cost is higher than the recommended max rent I got. — This is expected — the recommended max rent figure is based on income alone; utilities are added on top afterward to produce the separate total housing cost figure, so the two numbers aren't meant to match.
Terms Explained
Rent-to-income ratio: Monthly rent divided by monthly gross income, expressed as a percentage, used to flag a budget as Affordable, Moderate, or Cost-Burdened.
Cost-Burdened: The label applied when housing costs exceed 40% of gross income, a level widely associated with financial strain.
