Example Data Table

This example shows a monthly ecommerce support workload and the resulting inflow profile.

Period Days	Total Tickets	Total Orders	Customers	Agents	Hours/Day	AHT (min)	Reopened %	Daily Adjusted Inflow	Utilization
30	1,260	8,400	6,200	3	7	18	8	45.36	64.80%
14	980	4,700	3,950	2	8	16	5	73.50	122.50%

Formula Used

Daily Raw Inflow = Total Tickets ÷ Period Days

Adjusted Ticket Volume = Total Tickets × (1 + Reopened Rate ÷ 100)

Daily Adjusted Inflow = Adjusted Ticket Volume ÷ Period Days

Hourly Inflow = Daily Adjusted Inflow ÷ Support Hours per Day

Tickets per 100 Orders = (Adjusted Ticket Volume ÷ Total Orders) × 100

Tickets per 100 Customers = (Adjusted Ticket Volume ÷ Total Customers) × 100

Daily Capacity = (Support Agents × Support Hours per Day × 60) ÷ Average Handle Time

Capacity Utilization = (Daily Adjusted Inflow ÷ Daily Capacity) × 100

Daily Capacity Gap = Daily Capacity − Daily Adjusted Inflow

These formulas help ecommerce teams relate incoming support pressure to orders, customers, and staffing capacity in one view.

Frequently Asked Questions

1. What does ticket inflow rate measure?

It measures how quickly customer support requests enter your queue during a chosen period. Teams use it to compare demand with staffing and service capacity.

2. Why include reopened tickets?

Reopened issues add workload even if they began earlier. Including them gives a more realistic view of handling pressure and helps prevent underestimating staffing needs.

3. Why compare tickets with orders?

Tickets per 100 orders shows support demand relative to sales volume. This helps teams spot whether service quality is improving or worsening as order count changes.

4. What is capacity utilization?

Capacity utilization shows how much of your available support handling power is being consumed by incoming ticket demand. Higher percentages usually mean tighter queues and slower response times.

5. What does a negative capacity gap mean?

A negative gap means incoming demand exceeds estimated daily handling capacity. That usually signals rising backlog risk unless staffing, efficiency, or automation improves quickly.

6. Can I use weekly or monthly periods?

Yes. The calculator works with any period length, as long as tickets, orders, and customers all refer to the same date range.

7. Is average handle time required?

Yes, if you want staffing capacity and utilization metrics. Without handle time, you can still estimate inflow, but not whether agents can realistically absorb it.

8. When should I recalculate this metric?

Recalculate after campaigns, catalog changes, shipping disruptions, or staffing changes. Frequent reviews help teams catch service strain before customer satisfaction declines.
