How the 50/30/20 Budget Rule Works
Learn the 50/30/20 budgeting method and use a calculator to estimate your split.
Overview
The 50/30/20 rule is a simple budgeting framework. It suggests around 50% of income for needs, 30% for wants, and 20% for savings or debt reduction.
The formula
Needs = income × 50%, wants = income × 30%, savings = income × 20%
Worked example
If your monthly income is £2,000, a simple 50/30/20 split would suggest £1,000 for needs, £600 for wants, and £400 for savings or debt payoff.
