Put in your numbers. The gray line is bookings alone. The cyan line is the same bookings with your retention working on top of them. The gap between the two is the case for running expansion like a first-class motion.
Horizon
Defaults are an example: a Series B at $8M ARR, $150K/mo net-new, 110% NRR. Change them.
By month 24, expansion contributes 36% of your growth: $2.0M of ARR the additive plan never sees.

Part two · channels compound too
The same math runs across your channel mix. A YouTube engine feeds organic and search. Organic feeds paid efficiency. All of it feeds GEO, and GEO feeds them back. Channels run separately add. Channels run as one system multiply. Toggle a channel off and watch what it costs the others.

Enter what each channel sources in pipeline per month — its revenue contribution, not what you spend on it.

This is your assumption, not a benchmark. Set it to what you'd defend in a board meeting. Bright bar segments = the lift the other channels add.
The math
channel output = base × (1 + r)n−1
base: the pipeline that channel sources today, $/mo. Your number, from the inputs above.
r: cross-channel reinforcement. Your assumption, from the slider: currently 10%.
n−1: how many other live channels feed this one. Currently 3 (from the toggles).
Right now: every live channel runs at ×(1 + .10)3 = ×1.331. System = sum of all channel outputs. Dividend = system − sum of bases. No other inputs, no hidden constants.
Run separately, these 4 channels make $200K/mo of pipeline. Run as one system at 10% reinforcement: $266K/mo. A 33% dividend worth $794K a year, at no added spend.
