Budget Planner
Plan your monthly budget with the 50/30/20 rule and see where your money goes.
โน๏ธAbout This Calculator
You make $5,000/month after taxes. Under the 50/30/20 rule, that's $2,500 for needs, $1,500 for wants, and $1,000 for savings. Most people look at those numbers and think "that seems reasonable" โ then realize their rent alone is $1,800 and their needs are already at 60%. That gap between how you think you spend and how you actually spend is where this planner earns its keep. Enter your income and spending, and it tells you exactly where you stand against the 50/30/20 framework. No judgment, just numbers. It also shows what's left for savings after your real spending โ which for many people is the first honest look at why the savings account never seems to grow.
Frequently Asked Questions
What is the 50/30/20 budget rule?
After-tax income split three ways: 50% needs (rent, utilities, groceries, insurance, minimum debt payments, transportation to work), 30% wants (restaurants, entertainment, subscriptions, hobbies, vacations), 20% savings and extra debt payoff. It comes from Elizabeth Warren's book "All Your Worth." It's not perfect for everyone, but it's the simplest framework that actually covers the important categories.
What counts as a need vs. a want?
Quick test: would genuine harm come to you if you eliminated it for 6 months? Needs: rent, basic utilities, groceries, health insurance, minimum debt payments, getting to work. Wants: dining out, streaming, gym, new clothes, vacations. Gray areas exist โ a car is a need in suburban Texas and a want in Manhattan. Your $200/month grocery bill is a need; the $150 you spend on top of that at restaurants is a want.
What if my needs already exceed 50% of income?
Extremely common, especially in expensive cities where rent alone eats 35-40%. The biggest lever is usually housing โ a roommate can save $500-1,000/month overnight. Beyond that: shop insurance annually (auto and renters), refinance high-interest debt, and look hard at whether your car payment is really a "need" or if a cheaper car would work. Squeeze wants below 30% to compensate, but protect that 20% savings rate โ it's the only part of the budget that builds your future.
How much should I save each month?
20% of take-home is the target. Where that money goes, in priority order: (1) enough into 401k to get the full employer match โ that's free money, (2) $1,000 starter emergency fund, (3) high-interest debt payoff, (4) build full 3-6 month emergency fund, (5) max IRA ($7,000/year), (6) max 401k ($23,000/year), (7) taxable brokerage. If 20% feels impossible right now, start at 5% and increase by 1% every few months. Something beats nothing every time.
Is the 50/30/20 rule realistic for everyone?
No. It assumes middle-class income in a moderate cost-of-living area. If you're earning $35,000 in San Francisco, your needs alone might be 75% of income. If you're earning $200,000, you can probably save 40%. The rule's real value isn't as a prescription โ it's as a diagnostic tool. It shows you which category is eating a disproportionate share and where you have the most room to adjust.
What budgeting method actually works long-term?
The one you actually stick with. Zero-based budgeting (every dollar assigned a job, like YNAB) works great for detail-oriented people. 50/30/20 works for people who want a simple framework. "Pay yourself first" (automate savings, spend what's left) works for people who hate tracking anything. The common thread in all of them: automation. Set up an automatic transfer to savings the day your paycheck hits. If it never lands in your checking account, you won't spend it.
