Rent calculator
Rent-to-Income Ratio Calculator
Check what percentage of monthly income is taken by rent plus utilities.
When to use this calculator
Use this calculator to check housing pressure after utilities are included. It is useful when comparing apartments with different rent, utility responsibility, parking, and service fees.
A unit with lower rent can be worse if utilities are high. A slightly higher rent can be more predictable if major utilities are included.
Formula used
Rent-to-income ratio = (rent + utilities) ÷ income × 100.
The formula is intentionally simple so it can be used for quick planning. Real bills, quotes, and installation costs can include fixed fees, taxes, tiers, labor, product limits, and site-specific conditions that a calculator cannot see.
