The ROI of Cash Burn for SaaS Startups
What should be the return on investment of a startup’s cash burn? Fred Wilson posed this question last year in his post Some Thoughts on Burn Rates. In that post, he suggests, and I agree, that a 5x ROI on cash burn is a good target.
How does one calculate ROI? It’s a simple formula:
Cash_Burn_ROI = Revenue_Multiple/Revenue_Pay_Back_in_Years1
If a business is worth 7x revenues and revenue payback is 14 months, the burn ROI is 6x or 7 / 1.2. If a business is worth 5x revenues and revenue payback is 18 months, the ROI is 3x. Note, I’m using revenue payback, not gross margin payback here.
