📊 ERP Cost & Deployment Benchmarks
Total cost of ownership, cost per user, ROI payback, and the cloud-vs-on-premises breakeven year, computed at six company sizes — from a 25-seat rollout to a 1,000-seat one — using the exact same calculators as the rest of this site, not a static table someone typed once and forgot about.
Five-year total cost of ownership, by company size
Computed with the ERP TCO calculator’s formula from a licence, implementation, and training cost that scale with seat count, plus five years of maintenance at roughly 20% of licence value annually. See the assumption model below the table before comparing these to your own quote.
| Seats | Licence | Implementation | Training | Maintenance/yr | 5-yr TCO | Avg. cost/yr |
|---|---|---|---|---|---|---|
| 25 | $77,500 | $112,500 | $18,750 | $15,500 | $286,250 | $57,250 |
| 50 | $95,000 | $135,000 | $22,500 | $19,000 | $347,500 | $69,500 |
| 100 | $130,000 | $180,000 | $30,000 | $26,000 | $470,000 | $94,000 |
| 250 | $235,000 | $315,000 | $52,500 | $47,000 | $837,500 | $167,500 |
| 500 | $410,000 | $540,000 | $90,000 | $82,000 | $1,450,000 | $290,000 |
| 1000 | $760,000 | $990,000 | $165,000 | $152,000 | $2,675,000 | $535,000 |
Cost per user and ROI payback, by company size
Cost per user divides the 5-year TCO above across seats and the 60-month term, via the cost per user calculator. Payback period assumes a conservative $1,200/seat/year benefit and uses the ERP ROI calculator’s formula — your own benefit estimate, built the way our ROI worked example describes, will be more accurate than this generic assumption.
| Seats | Cost/user (5-yr) | Cost/user/month | ROI over 5 yrs | Payback period |
|---|---|---|---|---|
| 25 | $11,450 | $190.83 | -47.6% | 9.5 yrs |
| 50 | $6,950 | $115.83 | -13.7% | 5.8 yrs |
| 100 | $4,700 | $78.33 | 27.7% | 3.9 yrs |
| 250 | $3,350 | $55.83 | 79.1% | 2.8 yrs |
| 500 | $2,900 | $48.33 | 106.9% | 2.4 yrs |
| 1000 | $2,675 | $44.58 | 124.3% | 2.2 yrs |
Cloud vs. on-premises breakeven year, by company size
Using the cloud vs. on-premises calculator, with on-premises upfront cost set to licence + implementation, on-premises annual cost set to the maintenance figure above, and a modeled cloud subscription at roughly 22% of licence value per year. See our breakeven worked example for how sensitive this year is to your own numbers.
| Seats | On-prem upfront | On-prem annual | Modeled cloud/mo | Breakeven year |
|---|---|---|---|---|
| 25 | $190,000 | $15,500 | $1,421 | 15+ yrs |
| 50 | $230,000 | $19,000 | $1,742 | 15+ yrs |
| 100 | $310,000 | $26,000 | $2,383 | 15+ yrs |
| 250 | $550,000 | $47,000 | $4,308 | 15+ yrs |
| 500 | $950,000 | $82,000 | $7,517 | 15+ yrs |
| 1000 | $1,750,000 | $152,000 | $13,933 | 15+ yrs |
The assumption model, in full
Every number above is derived from a seat count using a fixed-plus-variable cost model, then run through the real calculator functions — nothing is a static, hand-maintained figure:
- Licence cost = $60,000 + ($700 × seats)
- Implementation cost = $90,000 + ($900 × seats)
- Training cost = $15,000 + ($150 × seats)
- Annual maintenance = 20% of licence cost
- Annual benefit (for ROI) = $1,200 × seats
- Modeled cloud monthly fee = 22% of licence cost, divided by 12
These are reasonable, documented planning assumptions, not a substitute for a real vendor quote. Use the TCO, ROI, cloud vs. on-premises, and cost per user calculators with your own numbers once you have them — that's what these tools are built for.
❓ Frequently Asked Questions
Where do the numbers on this page come from?
Every figure is computed at build time by calling the same TypeScript functions that power our interactive calculators (erpTco, erpRoi, cloudVsOnprem, costPerUser), fed by a documented per-seat assumption model shown below each table. Nothing on this page is a hand-typed result — if the calculators' formulas change, this page's numbers update automatically.
Why does cost per user drop as company size increases?
Because roughly $150,000 of the total cost at every tier is fixed — project management, core configuration, a baseline testing cycle — regardless of seat count. That fixed cost gets divided across more users at larger tiers, which is also why a 25-seat company's per-user cost is structurally higher than a 1,000-seat company's, even for a comparably standard implementation.
Should I use these benchmarks instead of getting my own vendor quote?
No — use them as a sanity check on a real quote, not a substitute for one. Actual implementation complexity, industry, and negotiated pricing move any real number away from a generic benchmark. If your quote is far outside the range shown for your seat count, that's a reason to ask why, not a reason to assume the benchmark is wrong.
Why is the cloud-vs-on-premises breakeven year similar across company sizes?
Because this model scales on-premises and cloud costs by roughly the same per-seat assumptions, the ratio between them — and therefore the year the two cost curves cross — stays in a similar range regardless of company size. A company with a genuinely different cost structure (heavier customization, a steeper cloud discount) should run its own numbers in the calculator rather than relying on this table's breakeven year.
