IPO Cost & Timeline Estimator

Estimate the indicative cost range and timeline of an SME IPO, category by category, with an interactive stage plan.

In short: SME IPO costs include merchant banking, legal, audit, exchange, registrar and marketing expenses — broadly a mix of fixed fees and percentages of the issue size. Timelines depend on readiness, diligence and regulatory review rather than a fixed schedule.

Indicative timeline

  1. Financial preparation and restatement

    Weeks 0–20 · 8–20 weeks · Restated financials, peer-review readiness, clean-up of accounts and secretarial records.

  2. Legal and financial due diligence

    Weeks 8–30 · 4–10 weeks · Merchant banker and counsel diligence over corporate, financial and regulatory history.

  3. Draft prospectus and filing

    Weeks 12–38 · 4–8 weeks · Preparation of the draft offer document, intermediary appointments and exchange filing.

  4. Exchange / regulatory review

    Weeks 16–54 · 6–16 weeks · Exchange observations, clarifications and in-principle approval.

  5. Issue preparation and marketing

    Weeks 16–44 · 3–6 weeks · Final offer document, pricing, anchor/investor outreach and issue logistics. Partly parallel to review.

  6. Issue opening, closing and allotment

    Weeks 22–58 · 2–4 weeks · Subscription window, basis of allotment and refunds.

  7. Listing and market-making commencement

    Weeks 24–61 · 1–3 weeks · Trading approval, listing and commencement of market-making where applicable.

Stages may run in parallel; the range reflects dependencies, not a guaranteed listing date.

Worked example

For a ₹20 Cr SME issue at typical readiness, the indicative total often lands in the ₹1.5–3.5 Cr zone across categories, over roughly 6–12 months — highly dependent on preparation quality.
