Formula
Total monthly housing = rent + utilities + renters insurance. Rent share = total monthly housing ÷ monthly income. Target rent = monthly income × target percentage − utilities − insurance.
Rent Calculator
Rent Calculator estimates total monthly rent burden from rent, utilities, renters insurance and income.
Worked example
With 5,500 monthly income, 1,650 rent, 220 utilities and 25 insurance, total monthly housing is 1,895 and the income share is about 34.5%.
Professional note
Use the weekly equivalent when comparing listings advertised weekly, but make the final decision from the monthly income share.
Regional and unit assumptions
Standard or basis: monthly cash-flow budgeting using user-entered take-home income and category spending, with weekly, fortnightly, monthly or yearly entry normalized to a monthly result. Currency labels are generic; local taxes, benefits, debt rules, account timing and cost-of-living categories vary by household and country.
Assumptions and limitations
- Income can be gross or take-home, but should be consistent with the user’s budget method.
- One-off moving costs, deposits, furnishing, parking and rent increases are not included.
- The target percentage is a planning threshold, not a rule.

Questions
How do I calculate a monthly budget?
Add monthly expenses, planned savings and any buffer, then subtract that planned outflow from take-home income. A positive result is surplus; a negative result is a shortfall.
Should savings be counted as an expense?
For planning, this calculator treats savings as a protected monthly outflow. That makes the surplus show what remains after the saving goal is funded.
What is a budget buffer?
A buffer is extra room added for irregular bills, underestimates or price changes. This page applies the buffer to spending categories and shows it separately.
What is a good savings rate?
There is no universal rate. The calculator shows savings as a percentage of take-home income so you can compare scenarios, but the right target depends on income, debt, family needs and risk.
What should I print for a household budget record?
Print income, each spending category, savings goal, buffer, surplus or shortfall, savings rate, formula, assumptions, page URL, date and notes about statement sources or changes to try next month.
Calculation note
Rent calculators are budget tools: they turn a lease price into the recurring housing share that has to coexist with bills, transport, food and savings.
Rent is more than base rent
Utilities and insurance can move the real monthly burden enough that they need to sit beside rent in the first calculation.
Income share gives the sanity check
A monthly rent number is easier to judge once it is compared with monthly income and a target housing share.
