The 30% rule — spending no more than 30% of gross income on housing — is the most widely cited benchmark for affordability. On a $50K salary, 0 cities (0%) meet this threshold. That's a tough market. We ran the numbers on 3 cities in Idaho using 2026 census, rent, and salary data. Nampa comes out on top — here's the full ranking and analysis.
Put it this way: the #1 spot goes to Nampa, and the breakdown explains why. Renters here pay $1,561/month — saving renters $4,008 per year compared to the national average. Meanwhile, Utilities is the standout at index 95, keeping costs manageable. The weak spot? Housing at 109. A 26% rent-to-income ratio keeps most households inside the safe zone. Solidly above average.
On a $50K salary, the key number is $1,250/month — that's 30% of gross, the standard affordability line. Nampa ($1,561/mo, 37%), Boise ($1,703/mo, 41%), Meridian ($1,954/mo, 47%) all clear that bar. After federal tax, FICA (7.65%), and state income tax, estimated take-home ranges from $37,275 to $37,275/year across these top picks.
Factor in the cost side, though, and the picture shifts. Idaho — pandemic migration boom has reshaped prices. The 3 cities we track here average a cost index of 110 and median income of $84,039. It lands right near the national baseline, which makes the differences between individual cities all the more important. The typical rent runs $1,739/month, which is $156 less than the national median.
