What Is Total Cost of Delivery?
Total Cost of Delivery (TCD) is the complete cost of producing a service outcome. It includes every resource consumed in the delivery process, attributed to specific clients, projects, and service lines.
Unlike traditional cost tracking that focuses only on billable hours, TCD captures the full economic reality of modern service delivery — where human expertise, AI capabilities, and specialized tools all contribute to the final deliverable.
TCD answers the question:
"What did it actually cost to deliver this service to this client?"
This isn't just an accounting exercise. When you know your true delivery cost, you can make better decisions about pricing, resource allocation, and service design.
Why TCD Matters Now
For decades, service delivery was straightforward: consultants worked hours, you tracked hours, you billed hours. Delivery cost was essentially labor cost.
That model is breaking down. Today's services are delivered through a blend of:
Human Expertise
Strategy, judgment, relationships
AI Capabilities
Analysis, generation, automation
Specialized Tools
Scanners, platforms, SaaS
Without TCD visibility, service organizations face critical blind spots:
The Three Components of TCD
Every service delivery involves some combination of these three cost categories:
1. Human Costs
The cost of people involved in delivery. This is what traditional PSA tools track well.
Includes:
- • Internal staff: salary ÷ productive hours + benefits + overhead
- • Contractors: contracted rate × hours
- • Partners/subcontractors: pass-through costs
💡 Industry average: Human costs are ~70-85% of TCD in traditional services
2. AI Costs
The cost of AI models, agents, and automation used in delivery. This is the emerging category that most organizations don't track at all.
Includes:
- • LLM API calls: tokens × cost per token (input + output)
- • Image generation: images × cost per image
- • Custom models: inference costs, fine-tuning amortization
- • AI agents: execution costs, orchestration overhead
💡 AI costs can range from 5-30% of TCD in AI-augmented services
3. Tool Costs
The cost of specialized software, platforms, and services used in delivery. Often absorbed as overhead, but increasingly should be allocated per-engagement.
Includes:
- • Per-use tools: scans, assessments, reports
- • Metered services: cloud computing, data processing
- • Licensed software: allocated portion of subscriptions
- • Specialized platforms: testing, monitoring, analytics
💡 Tool costs typically represent 3-15% of TCD
The TCD Equation
At its simplest, Total Cost of Delivery is an addition problem:
The Total Cost of Delivery Formula
What makes this challenging isn't the math — it's the attribution. Each cost component lives in a different system:
The magic happens when you bring these three streams together at the engagement level and connect them to revenue. That's when you can calculate true margins.
Traditional vs. Blended Delivery
The delivery composition has shifted dramatically in recent years:
100% Human — Consultant works 40 hours, client billed 40 hours
90% Human, 10% Tools — Tools are overhead, still billing human time
65% Human, 25% AI, 10% Tools — AI does significant work, but tracking is opaque
All components tracked — Know exactly what each engagement costs to deliver
The Key Insight
As AI takes on more delivery work, the old model of "hours × rate = cost" becomes increasingly misleading. You might have fewer human hours but higher AI costs — or vice versa. Without TCD, you're flying blind.
How to Calculate TCD
Here's a practical framework for calculating Total Cost of Delivery:
Calculate Human Costs
For each person involved in delivery:
Where: Fully Loaded Rate = (Salary + Benefits + Overhead) ÷ Productive Hours
Calculate AI Costs
For each AI service used in delivery:
+ Image Generation + Custom Model Inference + Agent Execution
Calculate Tool Costs
For each tool used in delivery:
Or: (Subscription Cost ÷ Total Usage) × Engagement Usage
Sum and Attribute to Engagement
Combine all costs at the engagement level:
Example: Cloud Migration Assessment
Pricing Implications
Understanding your TCD unlocks smarter pricing strategies:
Cost-Plus Pricing
TCD + target margin = price floor. Know your actual floor, not a guess.
Value-Based Pricing
Price based on value delivered, but TCD tells you your margin at any price point.
AI Pass-Through Pricing
Some services bill AI costs separately with a markup. TCD enables transparency.
The Bottom Line
Without TCD visibility, you don't know if you're making money on AI-augmented services. You might be selling $50 of AI work for $30 — or missing opportunities to price the efficiency gains you've created.
Common Mistakes
When organizations start tracking TCD, they often make these mistakes:
Treating AI costs as overhead
AI costs vary dramatically per engagement. Averaging across all work hides which services are profitable.
Attribute AI costs to specific engagements, ideally to specific tasks or deliverables.
Using bill rates instead of cost rates
Bill rates don't reflect your actual cost. You can't calculate margin with revenue numbers on both sides.
Calculate fully-loaded cost rates: (salary + benefits + overhead) ÷ productive hours.
Ignoring tool costs below a threshold
$200 scans add up. 50 engagements × $200 = $10,000 in invisible costs.
Track all material costs. Set a threshold if needed, but make it low (e.g., $10).
Only tracking at month-end
By month-end, it's too late to course-correct on an engagement going over budget.
Track TCD continuously as costs are incurred. Compare to budget in real-time.
Getting Started with TCD
Start tracking Total Cost of Delivery with these steps:
Establish cost rates
Calculate fully-loaded cost rates for each role. Update quarterly or when compensation changes.
Set up AI cost tracking
Use a routing layer like OpenRouter, or export from your API provider. Tag usage by engagement.
Catalog tool costs
List tools used in delivery with their cost model (per-use, metered, or subscription allocated).
Define attribution rules
Decide how costs flow to engagements. Direct attribution where possible, fair allocation otherwise.
Connect to revenue
Match TCD to engagement revenue to calculate margins. This is where insights emerge.
