Incremental revenue is the money a channel or action brings in above what you would have earned anyway. It is the difference between your total with something in place and your baseline without it. For any new revenue stream, this is the number that actually matters, because it separates genuine additions from figures that only look like growth.

How to measure incremental revenue

Incremental revenue = Total revenue with the channel - Baseline revenue without it

Incremental revenue = Total revenue with the channel - Baseline revenue without it

Incremental revenue = Total revenue with the channel - Baseline revenue without it

The baseline is the hard part. You need a credible read on what you would have earned without the new channel, often from a holdout group or a clean before-and-after window, so that any overlap with existing spend is subtracted out. Without that comparison, a rising total can be mistaken for a lift that was never really there.

Why the "incremental" part matters

The key question for any new revenue stream is whether it truly adds to the total or simply moves money around. Incremental revenue is the net new amount you would not have earned otherwise. A channel that reports big numbers but merely shifts purchases that would have happened anyway is not incremental; it is a reshuffle wearing a growth label.

A quick example

Suppose your app earns $40,000 a month, and after adding a new placement total revenue rises to $46,000 with no drop in your existing ads or purchases. The incremental revenue is $6,000, the genuine lift on top of the baseline.

Offerwalls as incremental revenue

An offerwall typically reaches users who were never going to make an IAP (In-App Purchase), so the money they generate by completing offers is additive rather than cannibalizing. It sits on top of your primary revenue instead of eating into it. Because RevU's offerwall is designed to monetize the non-paying majority, publishers can usually treat the earnings as a genuine lift to total revenue rather than a reshuffle of existing spend.

How to protect the lift

• Watch your baseline. Confirm that existing ad and purchase revenue holds steady after the new channel goes live.

• Target non-payers. Revenue from users who would never buy is the most clearly incremental.

• Keep the experience intact. A channel that lifts revenue but raises churn can erase its own gains over time.

Incremental revenue vs. total revenue

Total revenue is every dollar you collect; incremental revenue is only the dollars a specific action added. A channel can raise total revenue on paper while adding little that is incremental, if it simply captures spend that would have arrived through another path. When you evaluate a new stream, judge it on its incremental contribution and its effect on LTV (Lifetime Value), not on its headline total.

Common mistakes to avoid

• Counting cannibalized revenue as new. Money moved from one channel to another is not a lift.

• Skipping the baseline. Without a control or clean comparison, you cannot prove a number is incremental.

• Ignoring side effects. A channel that lifts revenue but harms retention may be less incremental than it looks.
