The Math of Sales

An interactive calculator for outbound: exactly what it takes. Dials, conversations, meetings. To hit a revenue goal by cold calling.

The idea

Cold-calling plans are usually built on vibes. "just make more calls." But it's arithmetic. Start from a revenue number and work backward through every conversion rate, and you get the one thing that actually matters: how many dials a day this goal requires. Most of the time the answer is either reassuring or brutally clarifying.

What I built

A single-page calculator that runs the funnel in reverse: revenue goal → deals needed → meetings → conversations → dials. Every conversion rate is a live slider, so you can see instantly how a two-point swing in connect rate changes the daily workload. Or whether the target is even reachable with the headcount you have.

No framework, no dependencies. It loads instantly and does the whole computation in the browser.
