Housing Budget Calculator Guide

Building a housing budget is about more than just rent or mortgage payments. You also need to plan for bills, insurance, maintenance and savings. This guide shows how to structure a housing budget and use the HouseBudget Calculator as a quick starting point.

Start with your take-home income

Note your reliable monthly income after tax. Many people aim to keep total housing costs within 25–35% of take-home pay, adjusting lower if debts or childcare costs are high.

List your essential housing costs

Add savings and goals

A strong budget sets aside money for emergencies and future plans. Consider allocating a portion of income to an emergency fund, overpayments, or saving for upgrades and furnishings.

Use the calculator to set your headline number

  1. Enter your income and debts into the HouseBudget Calculator.
  2. Choose a target percentage for housing to see a suggested rent or mortgage payment.
  3. Adjust the percentage until the suggested payment leaves room for bills and savings.
  4. Plug the final payment into your budget alongside other housing costs.

Review regularly

Revisit your housing budget when bills change, a tenancy renews or a mortgage fix ends. Rerunning the calculator with updated numbers keeps your plan realistic.
