Family Budget Calculator
The 50/30/20 rule - needs, wants, savings
How to Use This Calculator
Enter your monthly take-home pay - the amount that actually lands in your bank account after taxes - and the calculator splits it into the three categories of the 50/30/20 rule. It's meant as a starting framework, not a strict requirement.
What Is the 50/30/20 Rule?
It's a simple budgeting framework: 50% of your take-home pay goes to needs, 30% to wants, and 20% to savings or extra debt repayment. It doesn't require tracking every category of spending in detail - just three buckets.
| Category | Share | Includes |
|---|---|---|
| Needs | 50% | Housing, groceries, utilities, insurance, minimum debt payments, childcare |
| Wants | 30% | Dining out, entertainment, subscriptions, hobbies, travel |
| Savings | 20% | Emergency fund, retirement, extra debt payments, college savings |
A Worked Example
Wants: $5,000 × 30% = $1,500
Savings: $5,000 × 20% = $1,000
What If the Split Doesn't Fit?
In higher cost-of-living areas, needs can easily exceed 50% - rent alone might take that much. If that's your situation, a modified split like 60/20/20 or 65/15/20 is more realistic. The goal isn't hitting the exact numbers, it's keeping the three categories in balance and making sure something is always going toward savings.
Common Questions
- Gross or net income? Net - your actual take-home pay after taxes.
- Where do minimum debt payments go? Under needs. Anything extra beyond the minimum counts as savings.
- Should family finance tools like college savings come out of the 20%? Yes - college savings, retirement contributions, and emergency fund building all share that 20% slice.
