A budget is just your take-home pay, sorted into what it’s actually going to. Enter your monthly take-home pay and what you spend in each category above, and you’ll see exactly what’s allocated, what’s left over, and whether that’s on track. On a $5,000 monthly take-home with $3,800 spread across housing, food, transportation, and the rest, that leaves $1,200 unaccounted for — money that either needs an assigned job (the zero-based approach) or is a legitimate cushion (fine, under the simpler 50/30/20 approach). Neither method is “more correct” than the other; they’re two different answers to the same $1,200 question, and which one fits depends on how hands-on you want your budget to be.
50/30/20 vs. zero-based: which one is right for you
50/30/20 asks for one number — your take-home pay — and splits it into three buckets automatically: 50% needs, 30% wants, 20% savings and extra debt payment. It’s the right starting point if you want a budget without tracking ten separate categories every month.
Zero-based asks for more: every one of the ten categories below, filled in until the total matches your take-home pay exactly, dollar for dollar. It’s the right choice if you want full visibility into where every dollar goes, not just a rough three-way split.
Why take-home pay, not gross income
Every number on this page runs on take-home (net) pay — what actually lands in your account after taxes and deductions — not your gross salary. Budgeting against gross pay overstates what you actually have to allocate, since taxes and withholdings never reach your account in the first place; this calculator does no tax modeling of its own, it simply asks you for the number you already know from your pay stub.
Frequently asked questions
Which budgeting method should I use — 50/30/20 or zero-based?
50/30/20 is faster to set up and easier to maintain if you want a rough, reliable split without tracking every category. Zero-based takes more setup but gives every dollar a job — useful if you want full control or are working with a tight budget where "leftover" money needs a specific destination.
Should I use gross income or take-home pay for my budget?
Take-home (net) pay — what actually deposits after taxes and deductions. Budgeting against your gross salary overstates what you have available, since that money never reaches your account.
What if my expenses add up to more than my take-home pay?
That’s an over-budget result, and the fix is always the same: either raise income or lower spending in specific categories until the total comes back under your take-home pay. The calculator above flags this immediately rather than letting it go unnoticed until the bank balance does.
Do I need to track all ten categories every month?
Not necessarily — the ten categories (Housing, Food, Transportation, Utilities, Insurance, Healthcare, Debt Payment, Personal, Savings, Other) are here so nothing gets missed, but 50/30/20 mode collapses them into three buckets if that level of detail is more than you want to maintain.
Model assumptions & disclosures
Take-home (net) pay only — not gross income. Every figure this calculator shows is based on the monthly take-home pay you enter — what actually lands in your account after taxes and deductions. It never computes or models federal or state withholding, FICA, or any other deduction; enter the number you already know from your pay stub.
Fixed categories, no custom lines. Income, Housing, Food, Transportation, Utilities, Insurance, Healthcare, Monthly Debt Payment, Personal, Savings, and Other are the only categories modeled — there is no way to add a custom category. Costs that don't fit neatly (childcare, kids' activities, side income) should be folded into whichever existing category fits best.
