The Importance of an ROI Calculator for Maximising Your Investments

1. What is ROI and why is it so important?
The ROI (Return On Investment) measures the gain or loss generated by an investment, expressed as a percentage of the initial cost. Its basic formula is:
ROI = [(Net gain – Investment cost) / Investment cost] × 100

1️⃣ The initial investment (e.g. cost of an advertising campaign)
2️⃣ The profits generated (e.g. additional sales)

Practical example:
Investment : €5,000 in a Facebook campaign
Gains : €15,000 in related sales
Costs : €2,000 (creation, management, ancillary costs)
Calculation:
Net profit = €15,000 – €5,000 – €2,000 = €8,000
ROI = (€8,000 / €5,000) × 100 = 160%
👉 Result: For every euro invested, you earn €1.60.
A automated calculator performs these operations instantly, avoiding mistakes and time-saving.
