Activity-Based Costing Model
Calculate the true cost of products, services or customers by assigning resource costs to the activities that actually consume them. Build up to 23 activities, map as many as 20 costs to each activity and analyze unit economics across up to 39 products.

Walk through the activity setup, cost pools, cost-driver inputs, product usage assumptions and output analysis that converts operational activity into cost per unit and margin insight.
What the model includes
A transparent framework for tracing costs to products and services.
Define the activities that consume resources, calculate an activity rate from the appropriate cost driver and allocate those costs based on how each product, service or customer uses the activity.
Define up to 23 operating activities
Create the activity pools that reflect how work is actually performed, from purchasing and setup to processing, fulfillment and customer support.
Assign up to 20 costs to each activity
Build each activity's total cost from the relevant labor, overhead and other resource inputs instead of relying on one broad allocation percentage.
Define the driver units behind each activity
Enter the total cost-driver volume for the period so the model can calculate a transparent rate per order, setup, labor hour, machine hour or other driver.
Analyze as many as 39 products or services
Enter how many units of each activity every product, service or customer consumes and let the workbook allocate costs accordingly.
Calculate the total cost per offering
Combine activity allocations to see the full modeled cost to produce a product, deliver a service or support a specific customer group.
Compare current and target economics
Review revenue, cost, cost per unit, current gross profit and margin, target margin and the price adjustment implied by the target.
Use three input sheets and one output sheet
Move through a structured five-sheet workbook that includes three input tabs, a consolidated analysis tab and a dedicated instructions tab.
Expand and adapt the unlocked model
Inspect every calculation, change labels and assumptions, or extend the structure around the activities and cost objects used by your organization.
How activity-based costing works
Trace resource costs through activities to the final cost object.
The model replaces broad overhead allocations with a driver-based path that shows what creates the cost and which products, services or customers consume it.
Resources become activity cost pools
Group labor, occupancy, equipment, administration and other relevant costs around the operating activities that consume those resources.
Cost drivers create activity rates
Divide each activity's total cost by its total driver units to calculate a measurable cost per order, setup, hour, transaction or other operational driver.
Usage assigns costs to cost objects
Multiply the activity rate by the driver units consumed by each product, service or customer to reveal total cost, unit cost and the resulting profitability.
How to use it
Move from resource costs to actionable unit economics.
-
Define the activities
List the recurring activities required to produce an offering, deliver a service or support a customer and select a practical cost driver for each one.
-
Build the activity cost pools
Enter the resource costs associated with each activity and the total number of cost-driver units completed during the period.
-
Enter product or customer usage
Specify how many units of each activity are consumed by every product, service, project or customer group being analyzed.
-
Review cost and margin results
Compare total cost, unit cost, current pricing and target margin to identify repricing, process improvement or product-mix opportunities.
Who gets value from it
Built for teams that need a clearer view of what drives cost.
Manufacturers and product businesses
Allocate setup, purchasing, production, quality and fulfillment costs according to the activity each product actually requires.
Service businesses and agencies
Measure the cost of serving different clients, projects or customer cohorts and align pricing with target gross margins.
Controllers, accountants and FP&A teams
Replace broad overhead assumptions with auditable cost pools, cost drivers and product-level allocation logic.
Owners and operating managers
Identify low-margin offerings, expensive activities, resource bottlenecks and opportunities to improve pricing or processes.

A few useful details.
What is activity-based costing?
Activity-based costing allocates resource and overhead costs to operating activities, calculates a cost per driver unit and assigns those activity costs to products, services or customers based on actual usage.
How many activities and products can I model?
The workbook supports up to 23 activities and up to 39 products, services, projects or customer groups. Each activity can include as many as 20 individual cost inputs.
What can I use as a cost driver?
Use a measurable factor that reasonably causes the activity's cost, such as labor hours, machine hours, purchase orders, production runs, setups, shipments, transactions or service calls.
Can I use it for customer profitability?
Yes. Replace the product slots with customers or customer cohorts, then enter how many units of each service activity they consume to estimate the cost to serve and the gross margin by customer.
What analysis does the output provide?
The output shows total cost, cost per unit, current revenue and gross profit, current margin, target margin and the pricing adjustment indicated by your target economics.
Is the workbook editable and included in bundles?
Yes. The formulas and tabs are unlocked and editable. The model is also included in the Accounting Templates, Manufacturing Models and Super Smart bundles.
