About the Price Per Unit Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
Price per unit = price / quantity
Better value = lower price per unit
Savings% = (higher PPU - lower PPU) / higher PPU x 100
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: Price per unit = price / quantity Better value = lower price per unit Savings% = (higher PPU - lower PPU) / higher PPU x 100 Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Paper towels: 6-pack for $8.99 vs 12-pack for $15.49
Inputs
With Price - Option A = 8.99, Quantity - Option A = 6, Price - Option B = 15.49 and Quantity - Option B = 12 as the stated inputs, the result is Price Per Unit - A = $1.4983/unit, Price Per Unit - B = $1.2908/unit and Better Value = Option B is better value. Each value corresponds to the declared output fields.
Example 2: Laundry detergent: 50 oz for $6.99 vs 150 oz for $18.99
Inputs
With Price - Option A = 6.99, Quantity - Option A = 50, Price - Option B = 18.99 and Quantity - Option B = 150 as the stated inputs, the result is Price Per Unit - A = $0.1398/unit, Price Per Unit - B = $0.1266/unit and Better Value = Option B is better value. Each value corresponds to the declared output fields.
Example 3: Protein powder: 2 lb for $29.99 vs 5 lb for $59.99
Inputs
With Price - Option A = 29.99, Quantity - Option A = 32, Price - Option B = 59.99 and Quantity - Option B = 80 as the stated inputs, the result is Price Per Unit - A = $0.9372/unit, Price Per Unit - B = $0.7499/unit and Better Value = Option B is better value. Each value corresponds to the declared output fields.
Example 4: Coffee beans: 12 oz bag $14.99 vs 2 lb bag $34.99
Inputs
With Price - Option A = 14.99, Quantity - Option A = 12, Price - Option B = 34.99 and Quantity - Option B = 32 as the stated inputs, the result is Price Per Unit - A = $1.2492/unit, Price Per Unit - B = $1.0934/unit and Better Value = Option B is better value. Each value corresponds to the declared output fields.
