This approach splits your take-home pay into needs, wants, and savings to keep things dead-simple.
Before she was a United States senator, Elizabeth Warren was a professor. In her book All Your Worth: The Ultimate Lifetime Money Plan, she described a simple budgeting strategy called 50/30/20.
It's pretty straightforward: after taxes, roughly half of your income should cover essentials you can't avoid, about 30% can go toward things you enjoy, and at least 20% should fuel your financial future.
Plug in your monthly take-home pay below and the calculator will do the rest.
Enter your monthly after-tax income to see how the 50/30/20 rule divides your budget.
Needs are non-negotiable expenses: housing, groceries, utilities, insurance, minimum debt payments, and transportation.
If skipping a payment would create a real-world consequence — an eviction notice, a lapsed policy, or an empty fridge — it's a need.
The test is simple: would your life materially suffer without it?
Wants are everything that makes life enjoyable but that you could technically survive without: dining out, streaming subscriptions, fancy gym memberships, vacations, and so on.
This category often causes the most guilt, but the beauty of the 50/30/20 framework is that it gives you explicit permission to spend on joy, without exhausting or overextending your resources.
This is the bucket that builds your future. It includes emergency fund contributions, retirement savings (401(k), IRA, Roth), extra debt payments above the minimums, and any investing you do outside of retirement accounts.
No single budgeting framework works perfectly for everyone.
If you live in a high-cost-of-living city, your needs might swallow 60% or more of your income, and that's okay. The percentages are guardrails, not laws.
Some people prefer a 60/20/20 split, while aggressive savers targeting financial independence may flip it to 50/20/30 in favor of savings. The important thing is having a system at all.
If you're carrying high-interest debt, many financial planners suggest temporarily shifting money from the wants category into debt repayment. Once the debt is cleared, you can rebalance back to the standard 50/30/20 split and enjoy more breathing room. ⬥
