OpenFrequently asked questions
›What is a good ROI?
It depends on the asset. Broad stock market averages sit near 7–10% annually; marketing campaigns often target 300%+ because costs are recovered quickly.
›What's the difference between ROI and annualised ROI?
ROI is the total return over the whole holding period. Annualised ROI spreads that return across each year so investments of different lengths can be compared fairly.
›Should ROI include ongoing costs?
Yes. Add maintenance, fees and labour into your total investment figure, otherwise the ROI will look better than reality.
