How this is worked out

Takes 30% of your gross annual income and divides by 12. It also shows the income a 30 times monthly rent rule would require.

Worked example

  • Annual gross income £32,000

32,000 × 30% ÷ 12

£800.00 a month

Assumptions and limits

  • The 30% share is a common budgeting guide, not a rule. It is not a lettings affordability decision.
  • Based on gross income, so it takes no account of tax, debts, childcare or other commitments.
  • Letting agents commonly require annual income of 30 times the monthly rent, and may ask for a guarantor otherwise.
