Business Sales Calculator

Running a business requires careful financial planning, and understanding your sales metrics is crucial for success. That's why I created this Business Sales Calculator - a powerful tool that helps you analyze your sales performance with just a few inputs.

What This Calculator Does

This calculator takes three simple inputs:

1. Price per unit (your selling price)
2. Quantity sold (number of units sold)
3. Cost per unit (your production/purchase cost)

It then calculates 6 key metrics that every business owner should track:

1. Total Revenue

The total income generated from sales.

$\text{Total Revenue}=\text{Price per Unit}\times \text{Quantity Sold}$

2. Total Cost

The total cost incurred to produce/sell the items.

$\text{Total Cost}=\text{Cost per Unit}\times \text{Quantity Sold}$

3. Total Profit/Loss

The net gain or loss after subtracting costs from revenue.

$\text{Total Profit/Loss}=\text{Total Revenue}-\text{Total Cost}$

4. Gross Margin (%)

The percentage of revenue that exceeds the cost of goods sold (profitability indicator).

$\text{Gross Margin}=\left(\frac{\text{Total Revenue}-\text{Total Cost}}{\text{Total Revenue}}\right)\times 100$

5. Markup Percentage (%)

How much you’ve marked up the cost price to determine the selling price.

$\text{Markup Percentage}=\left(\frac{\text{Price per Unit}-\text{Cost per Unit}}{\text{Cost per Unit}}\right)\times 100$

6. Profit per Unit

The profit earned on each individual unit sold.

$\text{Profit per Unit}=\text{Price per Unit}-\text{Cost per Unit}$

Example Scenario: Selling Handmade Candles

Input Values:

• Price per Unit = $12.50
• Quantity Sold = 200 units
• Cost per Unit = $4.80

Calculations:

Total Revenue

$\$12.50\times 200=\$2,500$$$

Total Cost

$\$12.50\times 200=\$2,500$

Total Profit

$\$2500-\$960=\$1540\text{(Profit)}$

Gross Margin (%)

$\left( \frac{\$2500 - \$960}{\$2500} \right) \times 100 = 61.6\%$

Markup (%)

$\left( \frac{\$12.50 - \$4.80}{\$4.80} \right) \times 100 = 160.42\%$

Profit per Unit

$\$12.50 - \$4.80 = \$7.70$$$

$\backslash \$12.50\; \backslash times\; 200\; =\; \backslash \$2,\backslash !500$Key Features of the Calculator
