ERP & Business Software Calculators

ERP ROI Calculator

Estimate the return on an ERP project from its annual benefit, total investment, and horizon — cumulative benefit, net benefit, ROI percentage, and payback period in months

ERP TCO Calculator

Add licence, implementation, and training costs to recurring annual maintenance across your ownership horizon to see the total cost of ownership and the average cost per year

Net present value, internal rate of return and the real payback year — against a benefit that has to be earned rather than switched on. The other calculators here add nominal dollars across the horizon; this one does not

ERP Customisation Cost Calculator

What your customisations really cost once every upgrade retests them — the annuity the business case prices as a one-off, and why SaaS makes it bigger

Software License Cost Calculator

Price a per-seat SaaS or ERP subscription from the cost per user per month, the number of users, and the term — plus any one-off setup fee — as monthly, subscription, and all-in totals

IT Downtime Cost Calculator

Estimate the cost of an outage from revenue per hour, downtime duration, the share of productivity lost, and any recovery cost — the revenue/productivity loss and total incident cost

Cloud vs On-Premises Cost Calculator

Compare on-premises upfront plus annual operating cost against a flat monthly cloud fee over your horizon to see each total, which is cheaper, and by how much

Cost Per User Calculator

Divide a total software or ERP cost across your users to see the cost per user, and with a term the cost per user per month — benchmark per-seat spend against list prices

📊 ERP Cost & Deployment Benchmarks

Reference tables — TCO, cost per user, ROI payback, and the cloud-vs-on-premises breakeven year — computed at six company sizes with these same calculators, so the numbers never drift out of sync
