If you sell products online, you must know how to check your ads’ success. Two common numbers help you do this. They are TACoS and ACOS. Both show how well your ads work. But they are different. This article will explain what TACoS and ACOS are. You will also learn how to calculate them. We will help you choose which one to use for your e-commerce business.
What Is ACOS?
ACOS means Advertising Cost of Sale. It shows how much money you spend on ads compared to how much you make from those ads. In simple words, it tells you if your ads are worth the cost.
To find ACOS, use this formula:
| ACOS Formula |
|---|
| ACOS = (Total Ad Spend ÷ Total Sales from Ads) × 100 |
Example: If you spend $20 on ads and make $100 from those ads, your ACOS is (20 ÷ 100) × 100 = 20%. This means you spent 20% of your sales money on ads.
Why Is Acos Important?
- It shows if your ads make money.
- Helps you know when to stop or start ads.
- Lets you check which ads work best.
But ACOS only looks at sales from ads. It does not show total sales or overall business health.
What Is TACoS?
TACoS means Total Advertising Cost of Sale. It looks at all your sales, not just those from ads. TACoS shows how much you spend on ads compared to total sales. This helps you see the bigger picture.
To find TACoS, use this formula:
| TACoS Formula |
|---|
| TACoS = (Total Ad Spend ÷ Total Sales) × 100 |
Example: If you spend $20 on ads and make $200 total sales, your TACoS is (20 ÷ 200) × 100 = 10%. This means your ads cost 10% of all your sales.
Why Is Tacos Important?
- It shows ads’ impact on all sales.
- Helps you understand overall marketing success.
- Useful for long-term business growth.
TACoS gives a better view of your whole business.
Difference Between TACoS and ACOS
| Feature | ACOS | TACoS |
|---|---|---|
| Focus | Sales from ads only | All sales (ads + organic) |
| Formula | (Ad Spend ÷ Sales from Ads) × 100 | (Ad Spend ÷ Total Sales) × 100 |
| Use | Short-term ad performance | Long-term business health |
| Shows | Cost efficiency of ads | Ads’ effect on total sales |
How to Calculate ACOS and TACoS Step-by-Step
Step 1: Collect Data
You need two things:
- Total money spent on ads (Ad Spend).
- Total sales amount. For ACOS, use sales from ads only. For TACoS, use total sales.
Step 2: Calculate Acos
Divide ad spend by sales from ads. Then multiply by 100 to get a percent.
Step 3: Calculate Tacos
Divide ad spend by total sales. Then multiply by 100 to get a percent.
Step 4: Compare Results
Look at both numbers. ACOS tells you ad efficiency. TACoS shows overall impact.
When to Use ACOS and When to Use TACoS
Both numbers are useful. But they fit different goals.
Use Acos When:
- You want to check how ads perform now.
- You want to stop ads that cost too much.
- You run small or new ad campaigns.
Use Tacos When:
- You want to understand your whole business.
- You want to see if ads help organic sales.
- You run many ads over a long time.
Example: Using Both for Better Decisions
Imagine you sell shoes online.
- You spend $50 on ads in one month.
- You make $200 from sales via ads.
- Your total sales that month are $500.
Calculate ACOS:
ACOS = (50 ÷ 200) × 100 = 25%
Calculate TACoS:
TACoS = (50 ÷ 500) × 100 = 10%
What does this mean?
- Your ads cost 25% of ad sales. This is a bit high.
- Your ads cost 10% of total sales. This is more balanced.
This shows your ads help boost sales outside ads too.
Tips to Improve Your TACoS and ACOS
- Optimize your ads: Use good pictures and words.
- Choose the right keywords: Match what customers search for.
- Lower your ad spend: Stop ads that cost too much.
- Increase organic sales: Use social media and email.
- Check your numbers often: Make changes when needed.
Why Understanding Both Metrics Matters
Many sellers only look at ACOS. But this misses the full story. TACoS shows if ads help your whole business. It helps you plan better for the future.
Using both helps you:
- Save money on ads.
- Grow your brand.
- Sell more products.
- Keep your business healthy.

Both are important. Use ACOS to check ad efficiency. Use TACoS to understand overall sales impact.
