How it works
Compare rent with the full utility package
A listing at 1,200 with 250 utilities uses 1,450 monthly, more than a 1,350 listing including those utilities. Recalculate with each listing’s uncovered utility costs; advertised rent alone can reverse the affordability comparison.
Building a rent budget around other obligations
Use the rent budget as a starting point for comparing housing choices. The debt-adjusted mode shows how existing monthly obligations affect the amount available under the entered rule. Check which expenses are included before comparing the result with a rental listing. Utilities, transport, and irregular expenses may need their own allowance even when the advertised rent fits the estimate.
Rent budget: formula and assumptions
Monthly rent budget = annual income/12 × share − utilities.
A percentage rule is only a starting point. Debts, savings, location, and household needs matter.
Rent after monthly debt obligations: formula and assumptions
Rent allowance = max(0, gross monthly income × combined share − debt payments − utilities).
The share covers housing and debt together. This adjustable planning convention is not a landlord or lender eligibility rule.
Worked example
Reference example currency: USD. These fixed examples do not change with your calculator preferences.
Using the Rent budget example:
- Annual gross income ($)
- 75000
- Share allocated to rent (%)
- 30
- Monthly utilities budget ($)
- 150
Monthly rent budget = annual income/12 × share − utilities.
Example result
Monthly rent budget: $1,725.00

Common questions
Why are utilities deducted from the rent allowance?
The model treats the chosen income share as a housing budget, then reserves the entered utility amount before estimating rent.
Is the suggested percentage suitable for every household?
No. Debts, savings goals, household needs and local housing costs can make a percentage rule unsuitable.
