Check your understanding

What if there is no money left for rent?

The rent ceiling is zero. The cash available metric shows any shortfall before rent, so you can see which budget constraint binds.

What does the “Lower-income month” setting illustrate?

Try a month where cash remaining becomes the tighter constraint.

Behind the numbers

How this calculation works

The calculator compares remaining cash with your chosen housing share and takes the tighter limit. Utilities and recurring rental fees then reduce the base rent you can fit into that budget.

THE FORMULARent ceiling = max(0, min(take-home pay − debt − living expenses − savings, pay × housing share) − utilities).

A worked example

With 5,000 take-home income, the 35% housing cap is 1,750. The remaining cash is 1,900. After 200 of utilities, the lower housing cap leaves 1,550 for rent.

Good to know

Use consistent currency units and monthly amounts. Deposits, moving costs and landlord eligibility rules are separate.

How the inputs affect the result

Use an average that reflects irregular spending such as annual insurance, and keep rent-related charges out of the general expenses field. Variable income households can run a lower-income month as a separate case.
