Cost of Living Calculator

A cost of living calculator adds up your regular monthly bills and compares them with your income. Enter your housing, food, transport, utilities and other costs, plus your monthly income. The calculator shows your total expenses, what is left over, and the share of income you spend — updating as you type.

Estimates only. This tool is provided for educational purposes and is not financial advice. It models the figures you enter — it does not know your credit terms, local taxes, or fees. Talk to a licensed adviser before making a decision.

How to use the cost of living calculator

  1. Enter your housing cost — rent or mortgage each month.
  2. Enter your food and groceries spend.
  3. Enter transport — fuel, transit or car costs.
  4. Enter utilities — power, water, internet.
  5. Enter any other expenses and your monthly income.
  6. Read your total expenses, what is left, and the share of income spent.

Worked example

Your housing is $1,500, food $600, transport $300, utilities $200, other $400, and income $3,500. Total expenses are $3,000, you have $500 left, and you spend 86% of your income.

The math

total = housing + food + transport + utilities + other

leftover = income - total

share = total / income x 100

If your leftover is negative, your expenses exceed your income. Look for the largest category to cut first.

Frequently asked questions

What is a cost of living calculator?

It totals your regular monthly expenses — housing, food, transport, utilities and other costs — and compares them with your income so you can see what is left and how much of your pay you spend.

Why include utilities separately?

Utilities such as power, water and internet are recurring monthly bills. Tracking them separately helps you spot where costs creep up.

What if my expenses exceed my income?

A negative leftover means you are spending more than you earn. Review the largest category first and look for fixed costs you can reduce.

Should I use net or gross income?

Use your take-home (net) income after tax and deductions, so the comparison reflects the money actually available to spend.

Can I use it for a household?

Yes. Enter combined household expenses and combined income to see the whole household's monthly picture.
