Every calculator on the desk

Going public isn't one decision — it's four, in sequence. Cost sets the budget: what an S-1, Reg A+, or reverse merger actually consumes in underwriting, legal, audit, and exchange fees before you raise a dollar. Structure follows: what a new raise, a reverse split, or a warrant package does to authorized shares, public float, and the cap table you'll defend to the exchange. Eligibility narrows the field: whether OTCQB, OTCQX, or Nasdaq Capital Market will actually take the filing you're planning to submit, tested against bid price, holder count, and equity thresholds — not hope. Timeline closes the loop: turning the first three answers into a month-by-month critical path from kickoff to first trade. The ten instruments below map that order — start wherever your open question sits.

How the instruments fit together

Run them in this order and the last output — your timeline — stops being a guess. It's built from the cost, structure, and eligibility answers you already collected.

1. Cost — what capital you need to reserve before you raise anything

Every going-public path burns cash before it returns a dollar of proceeds. An S-1 underwritten offering, a Reg A+ Tier 2 raise, and a reverse merger into an existing shell carry different cost structures — underwriting spread, legal, PCAOB audit, exchange or marketplace entry fees, and the smaller line items (transfer agent, EDGAR filing agent, D&O insurance) that founders consistently underbudget. The IPO Cost Calculator is the entry point: pick a target market and a listing path, and it returns a sourced range, not a single number, because the real answer depends on the underwriter and counsel you eventually engage.

2. Structure — what the raise does to the cap table you'll defend

A cost estimate only means something once you know what it buys in ownership terms. The Dilution Calculator, Pre-IPO Valuation Calculator, and Authorized vs. Outstanding Calculator answer that — how a new raise, a warrant package, or a convertible note reshapes who owns what, whether your valuation range holds up against comparable listing paths, and whether your charter has room to issue the shares the deal requires without a shareholder vote to raise authorized capital. If the raise involves a corporate action to fix the share price — most commonly a reverse split ahead of an uplisting — the Reverse Stock Split Calculator models the post-split count, price, and the effect on your round-lot holder base, which is a separate test from the bid-price test and gets missed more often than it should.

3. Eligibility — which venue will actually take the filing

Cost and structure are inputs to a binary question: does this company currently qualify for the market it's targeting? The Nasdaq Requirements Checker and OTCQB Requirements Checker run your bid price, stockholders' equity, holder count, and public float against the live eligibility tests for each venue, standard by standard, rather than a single blended threshold. The Public Float Calculator feeds both of those checkers — it separates affiliate-held shares from freely tradable float, which is the number every exchange and marketplace actually tests, not shares outstanding. If the plan is to move up a tier rather than list fresh, the Uplisting Checker scores readiness across the same tests a national exchange will run before it accepts the application.

4. Timeline — sequencing the critical path to first trade

The first three answers converge in the IPO Timeline Generator, which turns your listing path and any eligibility gaps into a month-by-month critical path — audit lookback, S-1 or offering statement drafting and review, market maker sponsorship and Form 211 clearance for reverse mergers, DTC eligibility, and the exchange application window itself.

None of the ten instruments require an account, and none of them send your inputs anywhere — every calculation runs in the browser against the sourced figures in this site's public data file, dated . Treat the outputs as a way to walk into the first call with a banker, auditor, or securities counsel already knowing your rough number, not as a substitute for their engagement letter.

Frequently asked

What this index is for, and how to move through it.

Which calculator should I start with?

Start with cost. The IPO Cost Calculator is live now and answers the question every founder asks first — what does this actually cost across an S-1, Reg A+, or reverse merger. From there, work down the cost → structure → eligibility → timeline sequence described above; each stage's calculators build on the last one's answer.

Are these calculators free to use?

Yes. Every calculator and checker on this page runs for $0, with no account and no email gate. They're built as educational planning tools, not lead-capture forms — if you want a human to walk through the results, that's a separate, opt-in step via the Readiness Review.

Do the calculators cover Reg A+ and reverse mergers, or only a traditional S-1 IPO?

The IPO Cost Calculator already models all three paths side by side. As the remaining calculators in the "In development" state go live, each one carries the same multi-path treatment rather than assuming a traditional underwritten IPO is the only route to market.

How current are the underlying regulatory figures?

Every number the calculators read carries an as-of date and a confidence label in this site's public data file, last reviewed . Listing standards and fee schedules change — treat every output as a starting point and confirm the current standard with OTC Markets Group or Nasdaq, Inc. directly before relying on it.

What's the difference between a calculator and a checker on this hub?

A calculator (cost, dilution, valuation, timeline) models a dollar figure, share count, or date range from your inputs. A checker (Nasdaq, OTCQB, uplisting) tests your inputs against a venue's pass/fail eligibility standards and returns a verdict, standard by standard, rather than a single number.

Can I save or share a calculator result?

Where supported — starting with the IPO Cost Calculator — a "Copy link to this estimate" control writes your inputs into the page URL and copies it to your clipboard, so you can send an exact result to a co-founder, board member, or advisor without re-entering the numbers.
