Ad Spend-to-GMV Ratio
Definition
The ratio relates advertising spend to the explicitly defined gross merchandise value of a period.
For this entry, the ratio is defined as advertising spend divided by gross merchandise value (GMV). Multiplied by 100 yields a percentage value. Which orders and expenses are included must remain consistent for comparison.
Simply explained
With 10,000 euros in advertising expenses and 100,000 euros in merchandise value, the ratio calculated in this way is 10 percent.
Why it matters in practice
The metric describes advertising intensity relative to the merchandise value processed, not profit.
Example from business
Hypothetical example: A retailer compares the ratio monthly with identical rules for returns and considered advertising costs.
Limits and pitfalls
- GMV is neither automatically company revenue nor profit. With a GMV of zero, the ratio is undefined.
Origin & history
The representation connects two established operational metrics; there is no uniform general calculation rule for this exact combination.
Use in mid-sized companies
- Use as a clearly documented internal ratio together with margin and other results.
Frequently asked questions
Is this the reciprocal of ROAS?
Only if exactly the same revenue metric were used; GMV and advertising-attributed revenue are often different.
