ROAS Calculator

Formulas and Definitions

Revenue ($):

  • Definition: The total amount of money you make from selling your products or services. Think of it as all the money that comes in from sales.
  • Formula: Revenue = Price per Unit × Number of Units Sold

Margin (%):

  • Definition: This is the percentage of the revenue that is profit after you’ve paid for the costs of making the product. For example, if you sell something for $100 and it costs $60 to make, your margin is 40%.
  • Formula: Margin (%) = [(Revenue – Cost of Goods Sold) / Revenue] × 100

Gross Profit ($):

  • Definition: This is the actual profit you make after deducting the cost of making the product (Cost of Goods Sold or COGS) from the revenue. It’s what makes up the rest of your margin.
  • Formula: Net Profit = Revenue – Cost of Goods Sold (COGS)

Ad Spend ($):

  • Definition: The amount of money you spend on advertising your products or services. This includes all the money you put into ads to promote your business.
  • Formula: Ad Spend = Total Amount Spent on Advertising

ROAS (Return on Ad Spend):

  • Definition: This tells you how much money you make for every dollar you spend on ads. For example, if you make $5 for every $1 spent on ads, your ROAS is 5.
  • Formula: ROAS = Revenue from Ads / Ad Spend

Ad Agency Cost ($):

  • Definition: The amount of money you pay to a marketing or advertising agency if you hire one to handle your ads. This is an extra cost on top of your ad spend.
  • Formula: Ad Agency Cost = Total Amount Paid to Ad Agency

Net Profit after Costs ($):

  • Definition: This is your net profit after subtracting both the cost of making the product (COGS) and the money spent on advertising.
  • Formula: Profit after Costs = Net Profit – Ad Spend – Ad Agency Cost

ROI (Return on Investment) (%):

  • Definition: ROI (Return on Investment) is a percentage that tells you how much profit you make compared to what you spent on ads and other costs.
  • It’s like if you spent $1 on something and made $2, your ROI would show you made back your $1 and got an extra $1.
  • When we talk about ROI as a percentage, it shows how much more you made compared to what you spent. For example, if you spent $1 and made $2, your ROI would be 100%, meaning you doubled your money.
  • Formula: ROI (%) = [(Net Profit / Total Investment) × 100]

By understanding these simplified definitions and formulas, you can better grasp how each factor plays a role in calculating the profitability and efficiency of your advertising efforts.

Definition: ROAS measures the revenue generated for every dollar spent on advertising. It focuses specifically on the effectiveness of ad spend.

Formula: ROAS = Revenue from Ads / Ad Spend

Purpose: ROAS provides a targeted view of how effective advertising spend is in generating revenue. It helps businesses optimize their advertising budget and strategy.

Example: If you spent $1,000 on ads and generated $3,000 in revenue from those ads, your ROAS would be: ROAS = $3,000 / $1,000 = 3 (or 300%)

Definition: Profit After COGS and Ad Spend is the profit remaining after deducting the cost of goods sold and the ad spend from the net profit.

Formula: Profit After COGS and Ad Spend = Net Profit – Ad Spend – Ad Agency Cost

Purpose: This metric provides a clear picture of the remaining profit after covering all direct costs related to production and advertising.

Definition: Net Profit is the profit after deducting all costs, including the cost of goods sold (COGS) and ad spend. It represents the actual profit retained from revenue after covering all expenses.

Formula: Net Profit = Revenue – (COGS + Ad Spend)

Purpose: Net Profit helps you understand the actual profit generated from your operations after accounting for all costs.

Definition: ROI measures the profitability of an investment relative to its cost. It shows how much profit you gain from an investment as a percentage of the investment’s cost.

Formula: ROI = (Net Profit / Total Investment) * 100

Purpose: ROI provides a broad view of the overall profitability of an investment, considering all costs. It helps businesses understand the effectiveness of their total spending in generating profit.

Example: If you spent $1,000 on ads and an additional $500 on other costs, and generated $3,000 in revenue with a net profit of $1,500, your ROI would be: ROI = ($1,500 / $1,500) * 100 = 100%
