Application Managed Services ROI Calculator
EnterpriseTier AEvidence: application managed services (550/mo)
Application managed services replaces an internal ERP support team (or augments a thin one) with a provider that holds SLA-backed responsibility for application uptime, patching, and incident resolution. The return depends on what you are currently spending and what risk you are carrying.

Inputs
Input assumptions
| Input | Typical range | Notes |
|---|---|---|
| Internal ERP support headcount | 1–8 FTEs | Include direct IT staff and business super-users spending more than 30% of time on ERP support |
| Fully-loaded cost per FTE | $80,000–$160,000/yr | Salary, benefits, management overhead, recruitment. Use your HR figure, not salary alone. |
| Annual ERP vendor support cost | 18–22% of licence value/yr | SAP and Oracle typically charge 22%; NetSuite and Dynamics 365 bundle support in subscription |
| Unplanned downtime incidents/yr | 4–24 | Count P1 and P2 events from your ITSM data. If you do not have this number, estimate conservatively. |
| Business cost of one P1 hour | $5,000–$50,000 | Revenue impact plus idle labour. Varies enormously by industry and time-of-incident. |
| Average P1 resolution time (current) | 4–16 hours | Measure from ticket open to confirmed resolution, not from when the right person was reached. |
Formula
Calculation model
| Component | Formula |
|---|---|
| Current internal support cost | Headcount × fully-loaded cost per FTE |
| Current downtime cost | Incidents/yr × avg resolution hours × P1 hourly cost |
| Total current cost | Internal support + downtime cost + vendor support fees |
| Managed services fee (estimate) | $3,000–$25,000/month depending on application complexity and SLA tier |
| Downtime cost under managed services | Incidents/yr × provider SLA resolution time × P1 hourly cost (incidents typically reduce by 30–60% in year 1 due to proactive monitoring) |
| Net annual saving / cost | Total current cost − (managed services fee × 12 + new downtime cost) |
Stated assumptions
- The 30–60% incident reduction figure is a range drawn from provider case data; your actual result depends on the quality of your current monitoring and your provider's proactive tooling. Treat it as directional until you have 12 months of post-transition data.
- Managed services fees above do not include major upgrades or custom development. These are usually change-order items.
- The model does not capture risk transfer value (reduced key-person dependency, contractual SLA backing) — this is real but difficult to quantify.
- Internal headcount reallocation (not reduction) is the most common outcome in year 1. Full headcount reduction takes 18–24 months and depends on attrition.
When the ROI is strongest
- Your internal ERP support team is 1–2 people (key-person risk is high)
- Your current P1 resolution time exceeds 8 hours
- You are approaching a major upgrade and lack the internal expertise to run it
- Your ERP has more than 15 integrations (monitoring complexity exceeds small-team capacity)
