What Your Result Means
This shows what percentage of your income goes to needs, wants, and savings, compared against the widely-used 50/30/20 guideline. It also shows whether you have money left over or are spending more than you earn.
How It Is Calculated
Category % = (Category Spending / Monthly Income) × 100
Worked Example
On $5,000/month income with $2,200 in needs, $1,200 in wants, and $800 in savings, you're at 44% needs, 24% wants, 16% savings - with $800 left over to allocate.
Important Assumptions
- The 50/30/20 rule is a general guideline, not a strict requirement - adjust based on your cost of living and goals.
- Use after-tax (take-home) income for the most accurate percentages.
Frequently Asked Questions
- What counts as a 'need' vs a 'want'?
- Needs are essential and hard to reduce quickly - rent, groceries, utilities, insurance, minimum debt payments. Wants are discretionary - dining out, entertainment, subscriptions, hobbies.
- What if my needs are more than 50%?
- That's common in high cost-of-living areas. The 50/30/20 rule is a starting point - focus on spending less than you earn and building savings over time, even if your ratios differ.
