The global benchmark says you should spend no more than 30% of your gross income on housing. In Lagos, almost nobody hits it.
On a salary of ₦1 million a month, a level many Nigerians would consider comfortable, a decent 2-bedroom flat in Lagos eats 29% of your income. That sounds fine, until you realise it only just clears the benchmark. Drop to ₦500,000 a month, and the same flat takes 58%. Drop to ₦300,000 a month, and it takes 97%, almost everything you earn.
This isn’t a rule you’re failing to meet. It’s a rule the Nigerian rental market makes nearly impossible to meet at most income levels. Here’s what the numbers actually look like, and what most renters don’t yet realise about what comes next.
This analysis draws on findings from the Cowrywise Simplified Report on Rent vs Buy in Nigeria.
Where the 30% rule comes from
The idea that housing should cost no more than 30% of your gross income started in the United States, where it became the official affordability benchmark used by federal housing programmes. It then spread globally as a rule of thumb: short, memorable, easy to repeat.
The rule was designed around a market with stable rents, accessible mortgages, and income growth that broadly tracked housing costs. None of those conditions holds in Nigeria right now.
According to the Cowrywise Simplified Report on housing, Lagos rents grew by 12% to 18% year-on-year as of early 2026, and are projected to rise another 10% to 15% before the year ends. Meanwhile, house prices in nominal terms rose roughly 18% from January 2025 to January 2026. The rule didn’t account for an environment like this.
What rent actually eats at different income levels in Lagos
The Cowrywise report uses a reference property: a decent 2-bedroom flat in Lagos. The benchmark rent is ₦3,500,000 a year, which works out to roughly ₦292,000 a month. Here is how much of your income that single line item takes at different earning levels:
