To calculate Event ROI, you need to subtract the total expenses from the total revenue generated by the event, then divide this difference by the total expenses, and multiply by 100 to get a percentage. The formula is:
‍
ROI (%) = ((Total Revenue - Total Expenses) / Total Expenses) × 100

To calculate Event ROI, you need to gather the following data:
- Number of attendees
- Price per ticket
- Sponsorship revenue
- Exhibitor/vendor revenue
- Merchandising revenue
- Revenue from additional services
- Venue cost
- Technology cost
- Staff and labor cost
- Food and beverage cost
- Travel and accommodation cost
- Speakers cost
- Marketing and promotional cost
- Miscellaneous cost
- Leads generated (for cost per lead and intangible ROI)
- Projected revenue from follow-up sales (for intangible ROI)

Yes, this calculator can be used for various types of events including conferences, trade shows, virtual events, and more. You just need to input the relevant data specific to your event.

A good ROI for an event typically depends on the industry and the type of event. However, a positive ROI indicates that the event generated more revenue than it cost. Many consider an ROI of 10-20% to be satisfactory, but higher percentages are always better.

To improve the ROI of your events, you can:
- Increase ticket sales through effective marketing
- Secure more sponsorships
- Optimize costs by negotiating better rates with vendors and venues
- Enhance attendee experience to boost ticket prices
- Generate additional revenue streams such as merchandising and exhibitor fees

Sponsorship can significantly improve Event ROI by adding additional revenue streams without corresponding increases in expenses. It helps offset costs and increases the overall revenue, thereby improving the profit margin and ROI.
