What Does the Comp Sales Calculator Do?

This tool asks for two sets of input:

Current Period Data

Sales Revenue
Units Sold
Price per Unit
Cost per Unit

Comparison Period Data

Sales Revenue
Units Sold
Price per Unit

Then, it calculates and compares:

📈 Revenue Change
📅 Revenue per Day (Current)
🔄 Units Sold Change
💰 Profit Margin (Current & Comparison)
💵 Price per Unit Change

Why Is This Useful?

Quickly assess if your sales are up or down.
Understand whether the change is due to pricing, volume, or cost.
Optimize decisions like discounting, inventory restocking, or pricing strategies.

How Are Calculations Done?

Let’s break down the formulas used by the Comp Sales Calculator. All formulas are shown in LaTeX syntax for clarity.

🔹 1. Revenue Change

$Revenue Change (%) = (\frac{{Revenue}_{current} - {Revenue}_{comparison}}{{Revenue}_{comparison}}) \times 100$

🔹 2. Revenue per Day (Current)

If the current period is assumed to be 30 days (or user-defined), revenue per day is:

$Revenue per Day = \frac{{Revenue}_{current}}{Number of Days}$

🔹 3. Units Sold Change

$Units Sold Change (%) = (\frac{{Units}_{current} - {Units}_{comparison}}{{Units}_{comparison}}) \times 100$

🔹 4. Profit Margin (Current & Comparison)

$Profit Margin (%) = (\frac{Price per Unit - Cost per Unit}{Price per Unit}) \times 100$

Calculate this for both current and comparison periods.

🔹 5. Price per Unit Change

$Price Change (%) = (\frac{{Price}_{current} - {Price}_{comparison}}{{Price}_{comparison}}) \times 100$

Example Calculation

Let’s take an example with the following data:

🔸 Current Period:

Sales Revenue = $12,000
Units Sold = 400
Price per Unit = $30
Cost per Unit = $18

🔸 Comparison Period:

Sales Revenue = $10,000
Units Sold = 350
Price per Unit = $28
Cost per Unit = $16

1. Revenue Change:

$(\frac{12000 - 10000}{10000}) \times 100 = 20 %$

2. Revenue per Day (Assuming 30 days):

$\frac{12000}{30} = 400$

3. Units Sold Change:

$(\frac{400 - 350}{350}) \times 100 \approx 14.29 %$

4. Profit Margin (Current):

$(\frac{30 - 18}{30}) \times 100 = 40 %$

5. Profit Margin (Comparison):

$(\frac{28 - 16}{28}) \times 100 \approx 42.86 %$

6. Price Change:

$(\frac{30 - 28}{28}) \times 100 \approx 7.14 %$
