25 calculators

Growth & Marketing Calculator Suite

For marketing managers, founders & agency teams who want data-backed decisions across their digital presence. Benchmark performance, estimate cost of inaction, and prioritise fixes across web, SEO, ads, and e-commerce — all in one place.

You'll walk away with specific dollar figures for what slow pages, wasted ad spend, and weak content are costing right now — and a clear priority order for where to act first.

Revenue Intelligence & Profit Leak Diagnostics

For business owners & revenue leaders who suspect money is slipping through the cracks but haven't quantified it. Open this suite when leads aren't converting, ad spend isn't returning, or growth has stalled despite traffic.

You'll walk away with a live ticker showing what a slow site costs per hour, a funnel visualiser showing exactly where prospects drop, and a churn impact calculation that turns a percentage into a real annual number.
