Families and children

OECD Family database: the Family support calculator



How much income do families have and where does it come from? Find out how taxes and social benefits in OECD countries affect the incomes of families with children from before birth, during the years following a child's birth and in later years.

The OECD has taken the rules about who is entitled to what benefits and who should pay how much tax in different countries, and put them into one simple Family support calculator. This tool allows users to choose and compare the income situation of various family types as their children age - for the income year 2012 (version September 2014).

Calculations take into account Birth-related leave paymentssocial assistance benefitsfamily benefitshousing benefits and in-work benefits. Taxes and social security contributions due on earnings and benefits are also included in the calculations.

Key features of the calculator:

  • Explore how tax-benefit systems affect income changes at different stages of a child's life cycle.
  • Calculate the income situation of sole-parent or couple-parent families with differing earnings level.
  • Calculate the income of small and large families.
  • View charts providing detailed breakdown of earnings, benefits and taxes.
  • Compare the income situation between different types of families.
