Editorial policy

Last updated: August 5, 2026

This page explains how DoCalc researches, builds, fact-checks, and updates its calculators and articles — so you know exactly how much to trust a number before you rely on it.

Our editorial standard

Every calculator on DoCalc is built around a documented, industry-standard formula — never a formula we invented or approximated to make a result look better. Where a metric has more than one accepted definition (for example, Net Revenue Retention with or without upsells), we say so explicitly in the calculator's own explanation rather than silently picking one.

How a calculator gets built

1. Formula research. We start from how the metric is actually defined and used by the practitioners who rely on it — SaaS finance teams, lenders, investors, or industry bodies — cross-checking multiple credible references rather than a single source.
2. Build & test. We implement the calculation logic and test it against known reference values (published worked examples, textbook cases) before it ever ships.
3. Explanatory content. We write the surrounding article — what the metric means, how to read the result, common mistakes — after the math is verified, so the writing describes what the calculator actually does.
4. Publish. The page goes live with a visible "last updated" date and, where relevant, links to the external sources we drew from.

How we keep pages current

Formulas for well-established metrics (like MRR, compound interest, or loan amortization) rarely change, so those calculators are stable by design. Where a page cites external benchmarks, industry data, or figures that can shift over time, we review and refresh it periodically, and update the "last updated" date whenever we make a material change — a formula correction, a benchmark refresh, or a meaningful rewrite. Minor copy edits and typo fixes don't trigger a date change.

Sourcing standards

When we cite a source, we link directly to it rather than paraphrasing secondhand. We prefer, in rough order: primary/official sources (government agencies, standards bodies), established industry research (e.g. SaaS Capital, Bessemer, ChartMogul for SaaS benchmarks), and well-regarded reference publications. We avoid citing other calculator sites or content farms. Our current source list by category lives on the Sources & Methodology page.

Corrections

If a formula, figure, or explanation is wrong, we want to fix it fast. Report it to support@docalc.net with the page URL and what looks off. Confirmed errors in a live calculator are our highest priority and are typically corrected within a few days; we don't leave known errors live while we "get around to it."

Advertising & affiliate content

DoCalc runs a small amount of display advertising and may, in future, include affiliate links to relevant financial products. Advertising never influences which formula we use or what a calculator's output is — the math is the same whether or not an ad is present on the page. Any sponsored or affiliate content is clearly labeled as such; see About for how we make money.

Authorship

Content is attributed to "The DoCalc Team" because building and maintaining a calculator is rarely a one-person, one-time effort — see our Editorial Team page for who's behind that byline and how to reach us.
