Baseline case
A base of 1,200 customers churning 4% monthly, where a retention program trims churn by 1.5 points, modeled over 12 months at $129 ARPU.
Cutting churn from 4.0% to 2.5% keeps about 150 extra customers alive at the 12-month mark (886 versus 735) and adds $142,896 in cumulative revenue.

A 1.5-point churn improvement compounds into roughly $143,000 over a year. Retention work pays back quietly month after month, unlike a one-time acquisition push.

Larger customer base
Apply the same 1.5-point churn improvement to a bigger base of 1,380 customers.
Recovered customers rise to about 173 and cumulative revenue lift to $164,330, even though the churn rate still improves by the same 1.5 points.

The same retention gain is worth more on a larger base, because it acts on more accounts. Identical churn programs deliver outsized returns once you have scale to apply them to.

Lower starting churn
Run the program against a healthier base that already churns only 3.4% a month.
Improved churn drops to 1.9% and about 161 customers are recovered, with $149,281 in cumulative revenue lift, slightly more than the baseline despite starting lower.

A lower starting churn means more customers survive to benefit from the lift each month, so the recovered count edges up. Healthy bases compound retention gains more efficiently.

Stronger retention lift
Push the retention program harder so churn falls by 2.03 points rather than 1.5.
Improved churn falls to 1.97% and recovered customers jump to about 210, lifting cumulative revenue by $197,238, the largest gain of the four cases.

Deepening the churn cut from 1.5 to 2.03 points added roughly $54,000 over the baseline. The retention lift itself is the most direct lever, since it compounds against every month of the horizon.
