Methodology & Constants
This calculator implements the standard cash drawer reconciliation algorithm used in retail operations. The logic mirrors the physical act of counting bills and coins against the system's expectation.
Expected = Starting_Float + Total_Sales − Total_Refunds
Variance = Counted_Cash − Expected
Percent_Variance = (Variance ÷ Expected) × 100
Status = |Variance| ≤ $0.50 ? PASS : FAIL
Variance = Counted_Cash − Expected
Percent_Variance = (Variance ÷ Expected) × 100
Status = |Variance| ≤ $0.50 ? PASS : FAIL
Tolerance: ±$0.50 (industry standard for small-business retail).
Rationale: Accounts for rounding errors in coin handling and minor miscounts during high-volume shifts.
Agent-Legible Data: Constants and formulas exported to drawer-calculator.json for programmatic consumption.
Worked Example
A typical evening shift at the downtown store:
- Starting Float: $100.00
- Total Sales: $3,247.85
- Total Refunds: $12.50
- Counted Cash: $3,335.35
Calculation:
- Expected = 100.00 + 3,247.85 − 12.50 = $3,335.35
- Variance = 3,335.35 − 3,335.35 = $0.00
- Status: PASS
