How Much Should You Spend on Housing? A Country-by-Country Guide

The 30% rule — and why it is often wrong

You have probably heard the rule: spend no more than 30% of your income on housing. It originated in the United States as part of 1969 federal housing policy and has been repeated as gospel ever since. But it was never a universal truth — it was a policy threshold for subsidised housing in a specific country at a specific point in time.

In countries with strong public transport, lower average rents, or different cultural norms around homeownership, 20–25% is a more realistic target. In high-cost cities like New York, San Francisco, or London, even disciplined earners often pay 35–40%. The number that matters is your number — not an American rule from 1969.

What the data shows across 56 countries

We compiled housing expenditure data from national statistics offices — Destatis, INSEE, the BLS, the ABS, and others — to find the actual percentage that average households spend on housing in each country. Here is a sample:

Why the gap is so large

Several factors drive the difference between countries:

• Homeownership culture. Countries with high homeownership rates (like Norway and Singapore) often show lower housing cost percentages because mortgage costs are spread over decades and older owners have paid off their loans.
• Public housing supply. Singapore's HDB system keeps housing costs low relative to income. The UK's limited social housing stock pushes private renters toward 30–40%.
• Transport trade-offs. In cities with excellent public transport (Tokyo, Singapore), households save on cars — which effectively frees up budget for higher housing costs without reducing their overall standard of living.
• Wage levels. In emerging markets like India and Mexico, housing construction costs are low relative to income, so the percentage drops even if the absolute figure looks modest.

What this means for your budget

Rather than targeting a fixed percentage, treat housing cost as the anchor of your budget and work backwards. Ask:

1. What is your actual monthly take-home pay?
2. What are your fixed non-negotiable costs (healthcare, loan repayments, childcare)?
3. What remains for housing, food, transport, and savings?

If housing takes more than 35% of net income after all fixed costs, it is worth stress-testing your budget against a job loss or interest rate rise scenario. Our free budget builder lets you do this in a few minutes for your specific country.
