Frequently Asked Questions
How is ROI calculated?
ROI = (Net Gain ÷ Cost of Investment) × 100. If you invested $1,000 and earned $1,300, the net gain is $300 and ROI is 30%.
What is ROAS and how does it differ from ROI?
ROAS (Return on Ad Spend) = Revenue ÷ Ad Spend. It measures gross revenue per advertising dollar, ignoring other costs. ROI accounts for all costs and shows net profitability.
What is a good ROAS for paid advertising?
A ROAS of 4:1 ($4 revenue per $1 spent) is often cited as a break-even benchmark for e-commerce with 25% margins. Higher-margin businesses can be profitable at lower ROAS.
How do I calculate revenue growth rate?
Revenue Growth Rate = ((Current Period Revenue - Prior Period Revenue) ÷ Prior Period Revenue) × 100. A result of 15% means revenue grew 15% year-over-year.
