The 50/30/20 Budget Rule
Allocate 50% of take-home pay to needs (housing, food, utilities), 30% to wants (entertainment, dining out, subscriptions), and 20% to savings and debt repayment. Adjust percentages based on your financial goals and cost of living.
What is the Budget Calculator?
The Budget Calculator is a personal finance tool that categorizes your income and expenses. It utilizes the popular 50/30/20 rule to help you allocate your paycheck safely across Needs, Wants, and Savings.
How It Works (Algorithm)
The calculator asks for your net monthly income and automatically splits it into three rigid buckets. 50% is locked for necessities (rent, groceries, bills). 30% is allocated for discretionary fun (dining out, entertainment). The final 20% is strictly routed to savings or debt payoff.
$$ \text{Needs} = \text{Income} \times 0.50 \quad | \quad \text{Savings} = \text{Income} \times 0.20 $$

How to Use It
Enter your monthly take-home pay (after taxes). The calculator will instantly generate a perfectly balanced 50/30/20 budget. You can then enter your actual expenses to see if you are overspending in any specific category.
