What does this tool do?
Advisers often use a 30% rent-to-income guideline. This calculator shows your ratio, the rent at that benchmark and the gap, using gross monthly income.
The Formula
Rent ratio = Monthly rent ÷ Gross monthly income × 100Frequently Asked Questions
Is the 30% rule realistic?
It is a rough benchmark. In expensive cities many households spend more, while lower-income households often face higher ratios regardless of choice.
What income should I use?
Gross monthly income before tax, including stable regular income. Variable overtime or bonuses can be averaged but should not be assumed.
