LTV:CAC decides whether spending more is growth or a slow leak. Payback period decides whether you can afford it this quarter.

Every figure here is your own input and the arithmetic is plain - no hidden coefficients and no benchmark of ours baked in. Estimates, not a guarantee. Nothing is sent anywhere: the maths runs in your browser.
