About Zero-Based Budget Calculator
The Zero-Based Budget Calculator gives every single dollar of monthly income a specific purpose (spending, debt, or savings) until Income minus Expenses equals exactly $0.00.
Formula & Mathematical Calculation
Zero-Based Equation: Total Net Income - Total Living Expenses - Debt Payments - Savings Allocations = $0.00
Calculation Example
$6,000 Net Income: Housing ($2,000) + Living Costs ($1,800) + Debt Payments ($700) + Investments ($1,500) = $6,000 Total Outflow → Remaining Balance = $0.00 (Perfect Zero-Based Budget!).
