Formula & How It Works

ERP ROI measures how much financial value an ERP system delivers relative to its cost.

Annual Savings Breakdown

Inventory Savings = Revenue × Inventory Loss % × 30% reduction
Staff Savings = Hours Saved per Month × 12 × Hourly Cost
Billing Savings = Revenue × 0.5% (billing error reduction estimate)

ROI Formula

Annual Savings = Inventory + Staff + Billing Savings
ROI (%) = (Annual Savings − ERP Cost) ÷ ERP Cost × 100
Payback Period (months) = ERP Cost ÷ Annual Savings × 12

This calculator uses conservative industry benchmarks. Actual savings may be higher depending on your current level of manual operations.

Worked Example

Scenario: ₹50L annual revenue, ERP cost ₹36,000/year, 4% inventory loss, 40 staff hours saved/month at ₹80/hr.

Inventory Savings = ₹50,00,000 × 4% × 30% = ₹60,000

Staff Savings = 40 × 12 × ₹80 = ₹38,400

Billing Savings = ₹50,00,000 × 0.5% = ₹25,000

Total Savings = ₹1,23,400 | Net Benefit = ₹1,23,400 − ₹36,000 = ₹87,400

ROI = 87,400 ÷ 36,000 × 100 = 243% ROI | Payback: 3.5 months
