The System · The math

What does your marketing cost you today?

Most founders have never added it up: the drawer of subscriptions, the retainer, and the expensive part nobody counts — your own hours, valued at what they earn when pointed at your craft. Plug in your situation. The comparison appears as a consequence — and it models costs only, never promised outcomes.

Step 1

How does marketing get done today?

One tap. It seeds the comparison with typical numbers for your situation — every one adjustable below.

Answer the first question to begin.

How this is calculated

Transparent assumptions — shown, like everything else here.

The tool drawer (category midpoints)

Each item is a category, not a vendor — priced at the midpoint of typical small-business plans in 2026. Your real stack may cost more or less; toggle items off and edit nothing else, and the comparison follows. The Packages page lists what each Growyn capability retires.

Your hours (your number, our one assumption)

Hours per week × what your hour is worth × 4.33 weeks. The single assumption we make: on Growyn, hands-on time drops to roughly a fifth — approvals over coffee instead of doing the work — because that is the design goal of the whole system. If you think it’s a third instead, mentally scale it; the conclusion rarely changes.

The retainer (whatever yours is)

You type it; we don’t guess it. On the Growyn side it goes to zero — that’s the product. Why the system can be priced so far below an agency is answered honestly on the FAQ: software economics, plus the missing mystery premium.

What this deliberately leaves out

Revenue. The calculator models no growth, no conversion lifts, no “3x your leads” — we don’t promise outcomes anywhere on this site, and a calculator is no place to start. The comparison is strictly what marketing costs you, and it’s lopsided enough on costs alone.

A directional tool, not a quote. Your numbers depend on your actual stack, your hours, and your honesty with the inputs. The tier prices are real — Pricing has the full breakdown, and Packages lists what each capability retires.
