What is the 50/30/20 rule?

It's a budgeting guideline recommending that 50% of after-tax income is spent on needs, 30% on wants, and 20% to savings or debt repayments.

What counts as a 'Need'?

Needs include essential costs: rent/mortgage, groceries, utilities, insurance, transport, minimum debt payments.

What counts as a 'Want'?

Wants are non-essential: eating out, entertainment, holidays, subscriptions, luxury items.

How do I count savings or debt repayments?

Include putting money into a savings account, investing, or repaying any extra amounts on loans or credit cards beyond the minimum.

Is the 50/30/20 rule suitable for everyone?

It's a starting point. Adjust each category based on your situation, especially if your rent is high or you have unique financial goals.
