Budget Calculator
The 50 30 20 rule is the budget I give every pal who asks where to start. Half for needs, 30 percent for wants, 20 percent to save.
Type your income and see your own three buckets in real cash.
Rent, food, bills, transport. Fill it to compare with the rule.
Change it if 20 does not fit your life right now.
If your needs bucket is over half, that is normal in costly cities. Start by saving any small bit you can.
How to use this tool
- 1Take home income times 50 percent is your needs bucket.
- 2Times 30 percent is your wants bucket.
- 3Times 20 percent is your save bucket.
The math behind it
Left to plan = take home pay - needs - wants - saves
Take home 3,000 with 1,500 needs, 900 wants and 600 saves.
That is the classic fifty thirty twenty shape, and it balances.
Who this tool is for
I watch which tools folk open most, and this one gets used by the same kinds of people again and again. If any of these sound like you, you are in the right place.
- First time budgeters who want a shape to copy
- Folk whose budget keeps failing and want to know why
- Any one after a raise or a move, planing fresh
The 50 30 20 rule is the first money idea I ever loved, because it fits on a napkin. My first run showed needs at 68 percent. The rule did not shame me. It pointed at rent like a good pal does. Two moves later I was close enough to breathe.
Tips from me
- Start with last month's real spending, not a dream version of you.
- Give every dollar a job before the month starts. Jobs left open get spent.
- Leave a small buffer line. A budget with no air in it pops in week two.
Mistakes I see with this sum
These are the three slips I made my self or watch folk make most. Skip them and your number will be closer to the truth on the first try.
- 1Running it on gross pay. Take home is the only number that pays bills.
- 2Forcing the split on day one in a costly city. Aim at it, do not demand it.
- 3Calling debt pay backs wants. They are needs or future, never fun.
Two words worth knowing
Needs
The bills that keep life running. Rent, food, power, transport.
Wants
The fun stuff. Fine to have. Fine to cut too.
That is the whole page. The tool does the math, and the words above give it a shape. If a number still looks odd, change an input and watch what moves. Playing with the boxes taught me more than any guide did.
Common questions
+What counts as needs?
Rent, food, power, transport and the bills you can not skip. Shoes for work. Basic health care.
+My needs take 70 percent. What now?
You are not alone. Keep the rule as a target, cut one want at a time, and save even 2 percent to build the habit.
+What is the fifty thirty twenty rule?
Half your take home to needs, thirty percent to wants, twenty to saves and debts. It is a start shape, not a law.
+How often should I redo my budget?
Monthly, in one short sitting. Fifteen minutes with last month's numbers beats two hours of guessing.
+My budget never balances. Now what?
Cut the biggest leak first, not the most fun one. Rent, cars and food waste usually hide the real money.
