How to Use This Tool
Enter the total number of ad slots available for a given time period, then input how many of those slots have been sold or filled. Select the appropriate time frame and currency if tracking revenue. Click "Calculate Fill Rate" to see detailed results, or use "Reset" to clear all fields.
Formula and Logic
The fill rate is calculated as: (Sold Slots / Total Slots) × 100. This gives the percentage of inventory utilized. The tool also computes unsold slots and overall utilization rate, which helps in assessing performance against targets.
Practical Notes
- For e-commerce sellers, a fill rate above 80% often indicates strong demand; below 60% may suggest pricing or targeting issues.
- Consider seasonal trends: fill rates can fluctuate during holidays or sales events.
- Use this data to adjust ad pricing strategies—higher fill rates may allow for premium pricing.
- Track fill rates over time to identify market benchmarks and set realistic goals for your business.

Frequently Asked Questions
What if my sold slots exceed total slots?
The tool will show an error message, as this is invalid. Double-check your data entry—sold slots cannot be greater than available slots.
How often should I calculate fill rate?
For active campaigns, calculate weekly or monthly to monitor trends. For long-term planning, quarterly reviews are sufficient.
Can I use this for different currencies?
Yes, select your preferred currency from the dropdown. The fill rate calculation is currency-agnostic, but it helps contextualize revenue data.
Additional Guidance
Combine fill rate data with other metrics like click-through rates and conversion rates for a holistic view of ad performance. If fill rates are consistently low, consider revising ad creatives, targeting parameters, or pricing models to improve utilization.
