50/30/20 Budget Split Calculator
Split your take-home pay into 50% needs, 30% wants and 20% savings — the amounts you can spend and save each month.
How it works
Needs = income × 50% · Wants = income × 30% · Savings & debt = income × 20%
The 50/30/20 rule, popularized by Senator Elizabeth Warren, splits after-tax income into three buckets: 50% for needs (housing, groceries, utilities, minimum debt payments), 30% for wants (dining out, entertainment, subscriptions) and 20% for savings and extra debt payoff. It is deliberately coarse — a starting framework rather than a strict prescription. If your needs already exceed 50%, treat the target as a direction to move toward rather than a line you have failed to hit.
Worked example
On $4,000 of monthly take-home pay, the split is $2,000 for needs, $1,200 for wants and $800 for savings and extra debt. That $800 a month adds up to $9,600 a year set aside before any employer match or interest.
Frequently asked questions
Is the 50/30/20 rule based on gross or net income?
Net — your take-home pay after taxes and payroll deductions. Using gross income would overstate what you actually have to allocate, since a large slice never reaches your account.
What if my needs are more than 50%?
That is common in high-cost cities. Use the rule as a target to work toward: trim wants first, then look for ways to lower fixed costs like housing or transport. The 20% savings goal matters more than hitting exactly 50% on needs.
Do minimum debt payments count as needs or savings?
Minimum required payments are needs; anything extra you pay to accelerate payoff counts in the 20% savings-and-debt bucket, because it builds your net worth the same way saving does.
