What inputs does this calculator use?

Four: number of employees, your current ERP annual cost, expected operational efficiency gain (mid-market median is 6–10%), and average loaded employee cost (salary + benefits + overhead). Everything else is derived.

Why do I enter the implementation budget myself?

Because implementation cost depends on your scope: how many modules, how much data moves across, and what Odoo must connect to. We don't work from a price list, so the calculator uses the figure you enter, from a quote you hold or the budget you have in mind. Leave it at 0 to see savings before implementation. For your own number, book a free call: a one-week discovery ends with a fixed price.

Why is the efficiency gain halved in the calculation?

Because efficiency gains rarely convert 1:1 into reduced spend. We multiply the efficiency-gain figure by 0.5 to give a conservative floor — real engagements often unlock more, but we'd rather under-promise here.

What's included in the Odoo Enterprise SaaS cost?

We assume 50% of your workforce uses the system at $25/user/month, capped at 500 users. This excludes Odoo apps that have per-app fees and any third-party integrations or middleware.

How accurate is the payback period?

Directional, not exact. It assumes the legacy ERP retires by year 2 (so its annual cost stops compounding), and that efficiency savings are realised steadily across each year. Real timelines depend on go-live, change management, and adoption velocity.

Estimates use conservative defaults. Every implementation is priced to its scope: book a free call and you get a fixed price after discovery, before any build starts.

How we calculate this

Implementation cost: the one-time figure you enter. We don't supply one: every project is priced to its scope, with a fixed price after discovery.
Odoo Enterprise SaaS: 50% of your workforce as active users at $25/user/month, capped at 500 users.
Annual efficiency savings: total loaded payroll × efficiency gain × 0.5. The conservative factor reflects that not all efficiency converts to spend reduction in the same year.
Year 1: efficiency savings minus current ERP cost minus Odoo SaaS minus implementation. Years 2 and 3 drop the legacy ERP and implementation, so they typically swing strongly positive.
