The Free Discovery Call Calculator - How Much Are You Losing Every Year?

2026-05-06 · Norimitsu Shida · Kiruck Inc.

TL;DR

A practical ROI calculator for free discovery calls. Estimate annual opportunity loss and decide when to move to a paid Tenbin link.

The picture nobody adds up

A free 30-minute call, five times a week, across 46 working weeks is about 115 hours per year. At a USD 200 effective hourly rate, that is USD 23,000 of market-value time before paid work even starts.

The calculator below turns that into your own numbers so you can evaluate whether free intros are still marketing, or now a structural drag.

Replace it with a paid Tenbin link

Charge a small fee to filter signal from noise. Most users keep one free intro per month for warm referrals.

How to interpret the result

Under USD 5,000 net loss: keep free calls. USD 5,000-20,000: add async pre-screening and cap free slots. Over USD 20,000: move to a paid intro link and keep only a limited referral exception.
