Free Influencer Campaign ROI calculator with clear step-by-step results.

Orders
Orders = followers x engagement rate x click rate x conversion rate
Return on spend
ROAS = attributed revenue / (fee + gifted product cost)
Only loosely. Saves, shares and comments correlate with purchase intent far better than likes, and audience-brand fit outweighs the raw rate.
At cost, since that is the cash you actually forgo. Counting it at retail overstates the campaign spend and understates ROAS.
