What the 70/20/10 rule does

The 70/20/10 rule is a simple budgeting framework that splits your after-tax (take-home) income into three fixed buckets: 70% for living expenses, 20% for savings and investing, and 10% for debt repayment or giving. This calculator turns those percentages into dollar amounts. Enter your take-home pay (monthly or annual) and it returns the monthly allowance for each bucket, plus how much the 20% share adds up to over a full year.

The formula

  • Living expenses = take-home income × 0.70. Everything you spend to live — rent or mortgage, utilities, groceries, transport, insurance, subscriptions, and entertainment. Needs and wants share this one bucket, and required minimum debt payments count here too.
  • Savings and investing = take-home income × 0.20. Emergency fund contributions, retirement accounts, brokerage investments — money you keep.
  • Debt or giving = take-home income × 0.10. Extra debt payments beyond the required minimums, or charitable donations if you are debt-free.

If you enter annual income, the calculator divides by 12 to get a monthly figure first. The three buckets always sum to exactly 100% of the income you entered.

Interpreting the output

Compare the 70% allowance to what you actually spend each month — enter that figure in the optional field and the calculator does the comparison for you. If your spending fits inside the allowance, the 20% savings share and 10% debt-or-giving share are realistic targets. If it does not, the gap tells you exactly how many dollars to trim — or that the rule needs adapting to your situation, for example in a high-cost city where an 80/10/10 split may be a more honest starting point.

Next steps

  • Automate the 20% — a standing transfer to savings on payday makes the rule self-enforcing
  • Point the 10% at your highest-interest debt first, since the interest you avoid compounds in your favor
  • Re-run whenever your take-home pay changes; every bucket scales directly with income

Frequently Asked Questions

Is the 70/20/10 rule based on gross or take-home pay?
Take-home (after-tax) pay. Apply the percentages to what actually lands in your bank account after taxes and payroll deductions: 70% to living expenses, 20% to savings and investing, and 10% to debt repayment or giving. On $4,000 of monthly take-home pay that works out to $2,800, $800, and $400.
What counts in each 70/20/10 category?
The 70% bucket covers all living costs, needs and wants alike: housing, utilities, groceries, transport, insurance, subscriptions, and entertainment, including required minimum debt payments. The 20% bucket is money you keep — emergency fund, retirement accounts, and other investments. The 10% bucket goes to extra debt payments beyond the minimums, or to charitable giving if you are debt-free.
How is 70/20/10 different from the 50/30/20 rule?
Both allocate 20% of take-home pay to savings. The 50/30/20 rule splits spending into 50% needs and 30% wants, while 70/20/10 merges needs and wants into a single 70% bucket and dedicates the final 10% specifically to extra debt payments or donations. 70/20/10 is simpler to track day to day; 50/30/20 forces you to separate needs from wants.
