50/30/20 Budget Calculator
Compare your spending against the 50/30/20 budgeting rule by dividing your money into needs, wants, and savings/debt payoff. Use this calculator to see whether your current budget roughly fits the rule and where adjustments may be needed.
Burrow Tip: The 50/30/20 rule is a planning framework, not a law. The real value is seeing where your money is going and which category is crowding out the others.
If your needs are well above 50%, focus first on housing, transport, and fixed bills. If your wants are high, that is usually the easier category to trim.

How to use these results
The 50/30/20 rule is best used as a checkpoint, not a pass/fail grade. Your real question is: which category is taking too much room and what tradeoff does that create?
- If needs are too high: fixed costs are likely squeezing your budget, especially housing or transport.
- If wants are too high: you usually have more flexibility to cut here without destabilizing your life.
- If savings are too low: future goals, emergency reserves, or debt payoff are probably being delayed.
- If leftover is negative: your current plan is overspending, even before comparing to any budget rule.
A perfectly balanced 50/30/20 budget is not required. The point is clarity, control, and deliberate tradeoffs.
