ERP 3-year total cost of ownership estimator
Estimate a low–high range for three years of ERP subscription per user plus your one-off implementation, migration and training costs.
Choose the type of ERP you are considering, enter the number of full users (people who post transactions, not occasional viewers) and add your one-off costs from partner quotes. The tool multiplies users by a three-year per-user cost band and adds the one-off costs: total = users × 3-year cost per user + one-off costs.
The bands are illustrative only. They are not any vendor's price; they are built from a per-user monthly figure × 36 months so you can see the scale. Replace them with the figures in your own quote, including support plans and any base platform fee spread across users.
Worked example (illustrative): 15 users on a mid-market cloud ERP band of $4,320–$9,000 per user over three years gives $64,800–$135,000 of subscription. Add $60,000 of implementation, data migration, integrations and training and the three-year range is $124,800–$195,000, or roughly $41,600–$65,000 a year.
Limits: the tool does not model renewal uplifts (use the renewal uplift calculator), light or read-only user licences at a lower price, a minimum annual contract value, exchange-rate movements on USD pricing, internal staff time or GST. Read the 3–5-year TCO worked example for the full method.
