ROI & Payback Period Calculator

Return on investment (ROI) measures the revenue generated relative to the cost of a marketing campaign or channel. For B2B organisations, a healthy marketing ROI benchmark sits between 100–300%, meaning every dollar invested returns two to three dollars in revenue. Anything below 100% indicates you are spending more than you are earning — a situation that compounds quickly at scale.

Payback period — the time it takes for cumulative revenue to exceed cumulative investment — is equally critical for cash-flow planning. A 3-month payback is elite. Six months is healthy. Beyond nine months, you are carrying significant working capital risk, particularly in high-growth or venture-backed environments where capital efficiency is scrutinised heavily.

The most common cause of poor ROI in B2B marketing is not overspending — it is misattribution. Blended cost models hide the true cost of individual campaigns, making profitable channels look expensive and inefficient channels look acceptable. Disaggregating by channel is the first step to improving your return.
