Overview
The Family Cost of Living Calculator helps you estimate what your household may need each month and year to cover common living expenses. Enter your family size and regular costs for housing, food, transport, childcare, utilities and other spending to build a simple household budget estimate.
How it works
The calculator adds together the monthly costs you enter for key household spending categories to estimate your total monthly cost of living.
