Digitalization ROI: How to Calculate Return on Investment
"What does it return?" The question is legitimate before any digitalization investment. But answering it is not always simple: gains are multiple, sometimes indirect, and often difficult to quantify.
This guide offers you a structured method for calculating the ROI of your digitalization projects, with practical cases adapted to jewelry.
Why Calculate ROI
Beyond Intuition
Many digitalization projects are launched on the intuition that "it's necessary" or "everyone is doing it." These motivations are valid but insufficient to:
- Convince management or partners
- Prioritize between several projects
- Measure success after deployment
- Adjust if results are not forthcoming
Pitfalls to Avoid
| Pitfall | Consequence |
|---|---|
| Only counting costs | Biased decision, unjustified refusal |
| Overestimating gains | Disappointment, loss of credibility |
| Forgetting hidden costs | Budget overrun |
| Ignoring qualitative benefits | Underestimation of value |
| No post-project measurement | Impossible to know if successful |
The ROI Formula
Basic Calculation
ROI is calculated simply:
ROI = (Gains - Costs) / Costs x 100
Example
- Project costs: €30,000
- Gains generated: €45,000
- ROI = (45,000 - 30,000) / 30,000 x 100 = 50%
The Payback Period Concept
How long to recover the investment?
Payback period = Total costs / Annual gains
Example
- Total costs: €30,000
- Annual gains: €18,000
- Period = 30,000 / 18,000 = 1.7 years
TCO vs Initial Investment
TCO (Total Cost of Ownership) includes all costs over the lifespan:
TCO = Initial investment + Recurring costs over N years
This is the right figure to use when comparing solutions with different models (license vs SaaS).
Identifying Costs
Direct Costs
| Category | Elements | Estimation |
|---|---|---|
| Acquisition | License or subscription | Vendor quote |
| Implementation | Configuration, development | 30-100% of license |
| Migration | Existing data transfer | Variable |
| Training | Initial and ongoing | 5-10% of project |
| Infrastructure | Servers, network (if on-premise) | Variable |
Indirect Costs
| Category | Elements | How to estimate |
|---|---|---|
| Internal time | Hours spent by project team | Hours x hourly cost |
| Reduced productivity | Learning period | 10-20% of time over 2-3 months |
| Opportunity | What you do not do during the project | Subjective |
| Integration | Connection with other systems | Quote + time |
Recurring Costs
| Category | Frequency | Estimation |
|---|---|---|
| Maintenance / Support | Annual | 15-25% of license |
| SaaS subscription | Monthly/Annual | Vendor pricing |
| Upgrades | Variable | 5-15% per year |
| Ongoing training | Annual | 2-5% per year |
Non-Quality Costs
Do not forget current costs that digitalization will reduce:
- Errors and rework
- Time lost searching for information
- Delays and penalties
- Lost customers
Identifying Gains
Quantifiable Direct Gains
| Gain type | How to measure | Jewelry example |
|---|---|---|
| Time saved | Hours x hourly cost | -2h/day admin = €20k/year |
| Errors avoided | Average error cost x reduction | -50% errors = €8k/year |
| Increased productivity | Additional production | +15% orders = €25k/year |
| Reduced inventory | Immobilized value x rate | -20% stock = €10k/year |
Indirect Gains
| Gain type | Impact | Quantification |
|---|---|---|
| Customer satisfaction | Loyalty, recommendation | Customer lifetime value |
| Brand image | Attractiveness, premium | Difficult, estimate |
| Quality of life | Stress reduction, turnover | Avoided recruitment cost |
| Agility | Ability to seize opportunities | Subjective |
Avoided Gains (Costs Not Incurred)
| Avoided gain | Description |
|---|---|
| Recruitment | Volume absorption without hiring |
| Penalties | Avoided delivery delays |
| Disputes | Traceability reducing conflicts |
| Compliance | Avoiding regulatory sanctions |
Step-by-Step Calculation Method
Step 1: Define the Scope
Clarify what you are digitalizing:
- Which processes are concerned?
- How many people impacted?
- What volume processed?
Step 2: Measure the Current Situation
Before calculating gains, measure what exists:
| Indicator | How to measure | Current value |
|---|---|---|
| Admin time per order | Time tracking | X min |
| Number of errors per month | Counting | X |
| Average delivery time | History | X days |
| Delay rate | History | X% |
| Cost of an error | Estimate | X € |
Step 3: Estimate Improvements
Base yourself on:
- Vendor promises (with caution)
- Testimonials from similar customers
- Sector benchmarks
- Your own conservative estimate
Rule of caution: Divide commercial promises by 2.
Step 4: Calculate Annual Gains
Example: Administrative time savings
Current time per order: 45 min
Estimated time after digitalization: 15 min
Gain per order: 30 min
Number of orders/year: 1,000
Annual gain in hours: 500h
Loaded hourly cost: €35/h
Annual financial gain: €17,500
Step 5: Calculate ROI
Project costs (TCO 3 years)
- Subscription: €12,000 (€4,000/year x 3)
- Implementation: €8,000
- Training: €3,000
- Internal time: €5,000
Total: €28,000
Gains over 3 years
- Admin time: €52,500 (€17,500 x 3)
- Errors avoided: €24,000 (€8,000 x 3)
- Productivity: €30,000 (€10,000 x 3)
Total: €106,500
ROI = (106,500 - 28,000) / 28,000 x 100 = 280%
Payback period: 28,000 / 35,500 = 0.8 years

Measuring After Deployment
Indicators to Track
| Indicator | Frequency | Target |
|---|---|---|
| Admin time per order | Monthly | -50% |
| Error rate | Monthly | -50% |

| User satisfaction | Quarterly | Over 4/5 |
| Adoption (logins) | Monthly | 100% team |
Post-Project Review
6 months after deployment, take stock:
- Are expected gains achieved?
- Are there unanticipated gains?
- Additional costs?
- What needs adjusting?

ROI Calculation Pitfalls
Error 1: Ignoring the Cost of Status Quo
Doing nothing also has a cost:
- Loss of competitiveness
- Regulatory risks
- Team exhaustion
- Missed opportunities
Error 2: Too Short Horizon
A digitalization project's ROI is measured over 3-5 years, not 6 months. Do not be discouraged by a payback period of 18-24 months.
Error 3: Forgetting the Cumulative Effect
Gains accumulate year after year, while investment is one-time. Total value often exceeds simple ROI.
Error 4: Comparing Non-Comparable Things
A €10k solution and a €50k solution do not do the same thing. Compare ROI of solutions with equivalent scope.
