Write for us

We accept a small number of genuinely useful contributions from people who know their subject.

Almost everything on this site is written in-house alongside the tool it explains. We open that up occasionally, for one reason: sometimes a subject needs someone who has actually done the work — an underwriter, a dietitian, a quantity surveyor, a teacher. If that is you, we would like to hear from you. If it is not, this page will save us both an email.

Read this first: links are earned, not sold

We do not sell links, we do not accept payment for placement, and we do not run “sponsored post” arrangements dressed up as contributions. There is no price. Offers of one are declined without a reply, and repeat senders are blocked.

What we do offer a published contributor: a byline, a short author bio with one link to your own site or profile, and contextual links within the piece where they genuinely help the reader understand something. Whether a link stays, and whether it carries rel="nofollow", is an editorial decision we make and do not negotiate. If your pitch only makes sense as a way to place a link, it is not a pitch we can use. Commercial arrangements belong on the advertising page, where they are labelled as such.

What we publish

Explanations of the maths behind a decision. How an amortisation schedule actually front-loads interest; why two body-fat formulas disagree; what a lender is really testing with an affordability calculation.
Pieces built around a worked example. Real numbers a reader can follow with a pen, ideally ones they can reproduce in one of our calculators.
Practitioner knowledge. The thing that is obvious inside the industry and invisible outside it.
Corrections and expansions of our existing pages. If one of our explanations is thin or wrong, a pitch to fix it properly is very welcome.

What we do not publish

Anything generated by a language model and lightly edited. We can tell, and we check.
Content published elsewhere first, spun, translated from an existing post, or syndicated.
Listicles, “ultimate guides” assembled from other people's articles, and pieces written around a keyword rather than a question.
Personalised financial, legal, tax or medical advice. We explain how the numbers work; we do not tell readers what to do. See our disclaimer.
Gambling, payday and high-cost lending, debt relief, crypto speculation, essay-writing services, pharmaceuticals, and anything promoting a product we could not verify.
Undisclosed affiliate links, anywhere, ever.

Standards we hold you to

Cite a source a reader can check. Named, published formulas and primary sources — a regulator, a standards body, a peer-reviewed paper — not another blog post.
Show your working. If you assert a figure, show how it was derived or link to where it comes from.
Plain English. Short sentences, no marketing voice, no filler introduction explaining that budgeting is important.
Roughly 900–1,800 words, though a tight 700 beats a padded 2,000.
Disclose any interest. If you work for a company mentioned in the piece, say so in the pitch.

How it works

Pitch first, do not send a finished draft. A proposed title, the angle, the sources you would use and a couple of links to your published work.
We reply either way — usually within a few business days. A no is a no on the idea, not on you; you are welcome to pitch again.
We edit. Sometimes heavily, for accuracy, house style and length. You see the edit before it is published.
We fact-check every number against the source you cite and against our own tools. Anything we cannot verify comes out.
Published pieces stay maintained. If a rate or threshold changes later, we update the piece — and we may ask you to help.

Pitch us

One idea per pitch, please. Tell us the title you have in mind, who it is for, and why you are the person to write it.
