Monthly Budget Tracker

The 50/30/20 budget rule — calculator and how to use it

The 50/30/20 rule splits your take-home pay into three buckets: 50% needs, 30% wants and 20% savings and debt repayment. It's a starting point, not a law — use it to fill in the Planned column of the budget tracker.

What counts as a need, a want, or savings?

  • Needs (50%) — things you must pay to live and work: rent or mortgage, utilities, groceries, insurance, getting to work, minimum payments on debts.
  • Wants (30%) — things you choose: eating out, takeaway coffee, streaming, clothes beyond the basics, trips, hobbies.
  • Savings & debt (20%) — an emergency fund, retirement contributions, and paying debt off faster than the minimum.

When 50/30/20 doesn't fit

In expensive cities rent alone can take half of a first salary. That's common, not a failure: shrink the wants share first (for example 60/20/20 or 65/25/10) and keep some savings every month, even a small amount. If you have high-interest debt, many people put extra toward it before building savings beyond a small emergency buffer — what's right for you depends on your situation.
