pfin.budget-50-30-20 Calculator
Allocates take-home pay according to the 50/30/20 budget rule — 50% needs, 30% wants, 20% savings — and shows the gap between current spending and targets. The 50/30/20 framework is the most widely recommended budgeting starting point for its simplicity and balance.
Inputs
Take Home
Reference formula or conversion factor shown for context.
Needs
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Wants
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Savings
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Results
target needs (50%)
Sample size or count used in the calculation.
target wants (30%)
Sample size or count used in the calculation.
target savings (20%)
Total money or resources saved compared to the baseline or alternative scenario.
needs vs target
The current value compared to the goal. A positive number means the target is exceeded; negative means it is not yet met.
savings vs target
The current value compared to the goal. A positive number means the target is exceeded; negative means it is not yet met.
total
The combined total across all inputs and components.
