50/30/20 Budget Calculator
Turn monthly income into a simple first-pass budget.
Why the 50/30/20 rule works
It is simple enough to remember and flexible enough to use as a first draft. Many people need a starting framework before they can make better line-by-line decisions.
Treat it as a guide, not a law
High-cost cities, family obligations, and income volatility can make the numbers look different. The framework still helps by showing where the pressure is.
Use the savings slice on purpose
Savings can mean emergency reserves, debt payoff, investing, or a near-term goal. Pick one destination so the money does not disappear into vague intention.
Good follow-up question
After getting the number, ask what decision this result should help with next: comparing offers, quoting work, setting a budget, building a fund, or speeding up debt payoff.
Frequently asked questions
Should I use gross or take-home pay?
Take-home pay is usually better for budgeting because it reflects the money you can actually move.
What if my needs are above 50%?
That is common. Use the split to see the gap clearly, then work from there.
Can savings include debt payoff?
Yes. Many people use the 20% category for extra debt payments, savings, or investing.
