- The 50/30/20 split allocates take-home income: 50% needs, 30% wants, 20% savings or debt payoff.
- It's a guideline, not a hard rule — high cost-of-living areas often run needs above 50%.
- Needs are non-negotiable to function (rent, groceries, utilities, minimum debt payments); wants are discretionary.
- Hunch categorizes every transaction automatically so you always know where you stand against the split.
How the 50/30/20 calculator works
Enter your monthly take-home income and your spending by category — needs, wants, and savings. The calculator compares your actual percentages against the 50/30/20 guideline and shows where you're over or under.
The math: the 50/30/20 split
Each category's percentage = category spending ÷ total take-home income, expressed as a percentage. The guideline targets are 50% needs, 30% wants, 20% savings — the calculator shows your actual split next to these targets so you can see the gap at a glance.
Worked example
On $5,000/month take-home income: $2,800 in needs (56%), $1,200 in wants (24%), and $1,000 in savings (20%). Needs run 6 points over the 50% guideline — the calculator flags this, with savings already on target.
