Formel
How this is calculated
The most widely cited rental affordability guideline is the "30% rule": ideally your monthly rent should not exceed 30% of your gross monthly income. Above 30% is generally considered "cost-burdened"; above 50% is "severely cost-burdened." The rule originated from US housing policy research in the 1980s and remains a common benchmark for lenders, landlords and financial planners, though critics note it doesn't adapt well to very high or very low income levels or to cities with extreme rent-to-wage disparities.
Total housing cost includes rent plus utilities and recurring building fees. The housing-to-income ratio uses this broader figure, which is what landlords and mortgage lenders often ask about. Monthly surplus is income minus all expenses; a positive surplus is what's left for savings and unexpected costs.
The recommended maximum rent shown here is 30% of your entered gross income. This is a pre-tax guideline — if your take-home pay is significantly lower than gross, adjust the income field to your net (after-tax) income for a more conservative estimate. Neither this calculator nor the 30% rule accounts for asset wealth, debt obligations or local cost-of-living variation.
Häufige Fragen
The 30% rule says your monthly rent should be no more than 30% of your gross monthly income. For example, on a $5,000/month income, your rent should ideally stay at or below $1,500. It is a rule of thumb, not a legal limit — high earners can often afford more, and very-low-income renters may find 30% still leaves too little for necessities.
The 30% rule traditionally uses gross (pre-tax) income, because landlords typically check income before tax. For your personal budget, using your net take-home pay gives a more conservative and realistic affordability figure, since that is the money actually available to you.
It shows what fraction of your monthly income goes towards rent alone. Ratios below 30% are generally considered affordable; 30–50% is considered cost-burdened; above 50% is severely cost-burdened, leaving very little for food, transport, savings and emergencies.
