50/30/20 Budget Calculator: Your Target vs. What You’re Actually Spending
I already broke down how the 50/30/20 rule actually works, and where it falls apart, in a separate piece. This is the tool version, plug in your numbers and see exactly where you land instead of doing the math on a napkin.
Short version: enter your take-home pay, pick 50/30/20, 60/20/20, or 70/20/10 depending on how much room your needs actually take up, and you’ll get your target dollar amounts for each category. Fill in what you’re actually spending too, and the calculator grades you based on one thing specifically: whether you’re hitting your savings and debt payoff target, since that’s the number that actually matters, not whether every category lines up perfectly.
How to Use It
Start with your monthly take-home pay, the amount that actually lands in your account, not your salary before taxes and deductions.
Then pick your split. If your rent, utilities, groceries, transportation, and minimum debt payments genuinely eat up close to half your income, 50/30/20 is fine. If they run higher than that, and for a lot of people they do, 60/20/20 or 70/20/10 gives you a target that reflects your actual life instead of one you’re set up to fail from day one.
That alone gives you your target breakdown. If you want the calculator to actually tell you where you stand, not just where you should be, fill in what you’re really spending in each category too. That’s when the grade and the real feedback kick in.
Picking Your Split
50/30/20 is the standard version, and it’s the right starting point if your needs are genuinely moderate relative to your income.
60/20/20 fits a lot of people in higher cost-of-living areas or anyone supporting a household on one income. Same 20% protected for savings and debt, just more honest about what needs actually cost.
70/20/10 is for when needs are running seriously high and 20% toward savings still isn’t realistic yet. Even 10% consistently beats 20% you keep failing to hit.
The category that should never move, regardless of which split you pick, is savings and debt. That’s the whole point of the framework.
What the Grade Actually Means
The grade you get isn’t about hitting every category exactly. It’s specifically about how close your actual savings and debt payments are to your target for whichever split you picked. Hit 100% or more of that number and you get an A, regardless of whether your needs or wants ran a little over or under. Come in well under your savings target and the grade reflects that, even if your needs and wants both looked fine.
That’s deliberate. Being a little over on wants some months isn’t the thing that derails people long-term, quietly never getting around to the savings piece is.
Use your take-home pay, not your gross salary, the money that actually hits your bank account. Then pick the split that fits your real situation, not just the textbook 50/30/20.
If your needs genuinely run over 50% of your income, 60/20/20 or 70/20/10 is a more honest starting point. Protecting the savings percentage matters more than hitting the exact needs/wants split.
Fill these in to see how your real spending compares to your target, this is what actually tells you where you stand. Leave blank to just see your target breakdown.
