How this calculator helps
The headline number most renters care about is not just gross rent. Utilities, parking, renter’s insurance, and debt obligations all affect how much room is left in the month.
This calculator starts with your income and target housing percentage, then subtracts common non-rent housing costs so you can see a more practical rent target.
It is most useful as a planning tool before you tour apartments or compare listings in different neighborhoods.
How the math works
Monthly income = annual income / 12 when you choose annual income mode.
Maximum housing budget = monthly income × target housing percentage.
Recommended base rent = maximum housing budget - utilities - parking - renter’s insurance.
Worked examples
Single renter
A renter earns $72,000 per year and wants to stay near the classic 30% guideline.
- • Annual income: $72,000
- • Utilities: $150
- • Parking: $100
- • Insurance: $20
Monthly income is about $6,000, the housing budget is about $1,800, and base rent lands near $1,530.
Couple sharing income
A couple has $8,500 in monthly income and no parking cost.
- • Monthly income: $8,500
- • Target housing share: 28%
- • Utilities: $180
- • Insurance: $25
The target housing budget is about $2,380, leaving about $2,175 for base rent.
High-debt renter
A renter earns $5,000 per month but already has meaningful debt payments.
- • Monthly income: $5,000
- • Debt payments: $900
- • Utilities: $140
- • Parking: $150
The 30% budget is $1,500, but the heavy debt load suggests using a more conservative rent target.
