A 50/30/20 Budget App That Adjusts With Your Income
Split your take-home pay into needs, wants, and savings at a fixed ratio — three buckets to watch instead of fifteen categories to maintain.
The 50/30/20 rule splits your take-home pay into three buckets — needs, wants, and savings — at a fixed ratio, so you get budgeting guardrails without tracking fifteen individual categories. It's one of six budgeting methods built into Compound, so the split runs on your real bank data from day one instead of a spreadsheet you have to update by hand.
How the 50/30/20 Rule Works
You set three percentages that always add up to exactly 100: the classic split is 50% needs, 30% wants, 20% savings, but Compound also offers an aggressive-saver preset (60/20/20), a debt-focus preset (50/20/30), or a fully custom split with sliders that redistribute the other two automatically whenever you move one.
Dollar targets are shown next to each percentage and recalculate instantly from your income, so a raise or a pay cut updates every target immediately instead of leaving you to do the math yourself. Nothing is ever stored stale — the dollar figure is always derived from whatever your income is right now.
Inside Compound's 50/30/20 Dashboard
Your dashboard shows three rings, one per bucket, with the outer ring marking your dollar target and the inner fill showing actual spend so far this month — green under 90%, amber near the line, coral once you've gone over. A stacked bar underneath shows your real spending split at a glance, and every transaction carries a colored pill for its bucket that you can change with one tap. Compound's AI assigns the bucket automatically for new transactions; manual changes always win and teach the system for next time.
Is 50/30/20 Right for You?
50/30/20 is built for people who want real guardrails without micromanaging every subcategory of spending — three numbers to watch instead of fifteen. If you want to know exactly how much you spent on groceries versus dining out specifically, Compound's zero-based method or envelope budgeting give you that granularity — the trade is more setup and more categories to maintain. If even three buckets feels like more than you want to think about, Pay Yourself First strips budgeting down to a single savings number.
Switch Anytime — Nothing Gets Deleted
You're not locked into 50/30/20 forever. Change your method any time from Settings, and your percentages, bucket assignments, and history are archived, not erased. Switch away and come back within twelve months, and your split and your transaction history are exactly as you left them.
50/30/20 Budgeting, Answered
Do the 50/30/20 percentages have to be exactly 50, 30, and 20?
No. Those are the classic split, but Compound also offers an aggressive-saver preset (60/20/20), a debt-focus preset (50/20/30), or fully custom percentages — the only rule is the three numbers always add up to exactly 100%.
What happens to my dollar targets if my income changes?
They recalculate automatically. Compound derives each bucket's dollar target from your current income every time you view your budget, so a raise or a pay cut updates every target instantly without you doing any math.
Do I have to categorize every transaction myself?
No. Compound's AI assigns a bucket to new transactions automatically, and you can change any pill with one tap if it gets one wrong. Manual changes always win and teach the system for next time.
What counts as a 'need' versus a 'want'?
You decide — Compound lets you assign example categories to each bucket during setup (rent under needs, streaming under wants, for instance) and you can move any category between buckets later if your definition changes.
Three buckets. Zero spreadsheets.
