Two calculators that do the work before we ask you for anything


No account, no email, no partial answer held back. Both run in your browser, show their working, and give you something you can paste straight into a synopsis or a planner.


The tools

Available now

What each one does


  1. Tool 01

    Sample size calculator

    For: Anyone writing a synopsis or answering a committee's query about numbers

    The four designs most postgraduate theses use — estimating a prevalence, comparing two means, comparing two proportions and diagnostic accuracy — plus correlation. It shows the formula, the values substituted into it, and the arithmetic, so you can defend the number rather than only quote it.

    What it gives you

    • The required n, per group and in total, rounded up
    • Attrition applied, so the figure you write is the figure you recruit to
    • A methods sentence you can paste into your synopsis, with your own citation to fill in
    • The questions an examiner tends to ask about it

  2. Tool 02

    DNB and DrNB deadline planner

    For: NBEMS trainees, from the day they join

    Give it your joining date and it returns the dated timeline NBEMS publishes[2]: the protocol with ethics approval inside 180 days, data collection complete by 24 months, the thesis at 26 months, and which examination cut-off that falls before. Planning milestones we suggest are marked separately from the rules NBEMS sets.

    What it gives you

    • Every statutory date, with how far away it is in plain words
    • Which examination cut-off your submission date falls before, and the margin
    • A calendar file for the statutory dates
    • A plain dated list you can paste anywhere

What they are not

Read this first

A planning aid, not an authority


A calculator applies a formula to the values you give it. It cannot tell you whether those values are the right ones, and that is the part an examiner asks about. Where a tool needs an assumed figure — a prevalence, a standard deviation, a difference worth detecting — it has to come from published work that you cite, and the citation is yours to supply.

The deadline planner reproduces dates NBEMS publishes[2]. NBEMS may revise them, and your own institution may set something stricter. Confirm against the current circular and your programme before you rely on any date here.

Neither tool involves us. Nothing you type is sent anywhere, nothing is stored, and no result here has been approved by anyone. Your guide and your institution decide.

Protection of your work

  • Row-level security

    Every table enforces row-level access. You read your own record, and nothing else.

  • View-only streaming

    Drafts are streamed to you through an authenticated route, not handed over as a file.

  • Watermarked to you

    Every page you read carries your own name and email across it.

  • Download gated

    The final file unlocks when the fee is settled in full, and not before.

  • Mumbai region · DPDP 2023

    Your record and your documents are held in the Mumbai region, so India's Digital Personal Data Protection Act 2023 applies to them.

  • Anonymised data only

    We accept no patient identifiers. An NDA is available on request.

How this works

Instruments we work to

  • NMC PGMER-2023

    The thesis obligations set out in the postgraduate medical education regulations.

  • NBEMS

    DNB and DrNB protocol and thesis timelines, and the page limit, as published.

  • UGC 2018 · <10%

    The academic integrity convention we work to on every draft.

  • ICMJE · Vancouver

    Authorship criteria and reference style, applied as published.

  • No affiliation

    We work to these published instruments. We are affiliated to none of the bodies that issue them.

How this works

Authorship and the uniqueness check

  • Sole author

    Mentoring, editing, statistics and compliance. You remain the sole author of your thesis.

  • Not ghostwriting

    We will not write your thesis for you, and we will not be named in it.

  • MDSoftune

    Word-level uniqueness checking, built with REDENN Informatics Inc., Canada.

  • Every version

    Each draft is checked word by word before your university sees it.

How this works

MDThesis is an independent academic mentorship practice. It is not affiliated with, endorsed by, or acting for the NMC, NBEMS, UGC or any university.
