How to Calculate Cost Optimization and ROI for Custom Enterprise Software
Table of Contents — English
Introduction
The ROI of a custom software investment cannot be calculated by looking at the initial cost. A correct analysis covers the 5-year total cost of ownership, the operational capacity recovered, and the new revenue created.
The Right Framework for ROI Calculation
The ROI of a custom software investment cannot be calculated by looking at the initial development cost. A correct analysis covers, together, the 5-year total cost of ownership (TCO), the operational capacity recovered, and the new revenue created.
TCO Components
A 5-year TCO analysis includes these line items: development cost (year 1), annual maintenance and enhancement (years 2–5), infrastructure and hosting, security and compliance, training and change management, and the recovered labor cost (a negative line item — a gain).
ROI Calculation Steps
- Calculate annual operational savings: the labor cost recovered through automation
- Estimate new revenue: the additional sales capacity created through digitalization
- Calculate 5-year TCO: the sum of all cost line items
- ROI = (5-year total gain − 5-year TCO) / 5-year TCO × 100
