Who we are
prenatalcalculator.com is a free online resource offering pregnancy calculators, baby planning tools, and parenting guides. The United Kingdom edition has been adapted to use local terminology, currency (GBP), and guidance from GP, health visitor, or NHS.
Our mission
Pregnancy and parenting come with hundreds of small decisions: when is my due date, how much will the first year cost, is my baby's weight on track, which vaccines are due. Most people Google these one at a time and get fragmented answers across ten different websites — many with ads, signup walls, or content that isn't accurate for their country.
We built prenatalcalculator.com to be one trustworthy place where parents can answer these questions quickly. Every tool is free, none require an account, and none collect personal information beyond what's necessary to compute the result in your browser.
Editorial standards
- Country-specific: Every tool on the United Kingdom edition uses local conventions — measurement units, currency, leave entitlements, and health guidance applicable in United Kingdom.
- Reviewed: Medical content is reviewed against guidelines from GP, health visitor, or NHS (NICE guidance). We are not a replacement for medical advice — always consult your own healthcare provider for medical decisions.
- No fake numbers: Where we cite statistics or recommendations, we link to the original source. Where there's uncertainty, we say so.
- No ads in tools: Tool pages do not show third-party advertising. We may add sponsored content on guide articles in future, clearly labelled.
Privacy commitment
All calculator tools run entirely in your browser. We do not send your inputs (due dates, weights, names you're considering, etc.) to any server. Read our full Privacy Policy for details.
Who is behind this
prenatalcalculator.com is operated by a small team of parents, developers, and content reviewers. We don't list individual names publicly because the team is small and changes over time, but you can reach us at hello@prenatalcalculator.com for any editorial or technical question.
