As answered by people managing DeveloperToolStack and TheBaseRate.money.
TheBaseRate.money's answer:
Most UK money calculators give you a number. The Base Rate gives you the real one and shows its working. Every figure is checked against primary sources (gov.uk, HMRC, the Bank of England, the ONS) and re-verified each tax year, and each tool surfaces the insight others skip: the median Premium Bonds prize rather than the flattering average, what a student loan actually costs in today's money before it's written off, the marginal-rate traps hidden in the tax system. Free, no sign-up, no cookies, and it runs entirely in your browser.
TheBaseRate.money's answer:
A deliberately simple, fast static site: hand-written HTML, CSS and vanilla JavaScript, no framework, so every calculation runs instantly in the browser with nothing sent to a server. Fonts are self-hosted, with no third-party tracking beyond privacy-respecting analytics.
TheBaseRate.money's answer:
Three reasons. Accurate: every figure is sourced from gov.uk and HMRC and re-checked each tax year, and each calculator publishes what it does not model, so you know the limits. Honest: no sign-up, no cookies, nothing you type leaves your browser, and no product is ranked or sold to you. Clear: the tools answer a real decision, like what actually lands after tax, whether you'll ever clear a loan, or how big a pot you really need, not just arithmetic.
TheBaseRate.money's answer:
UK adults working out a real money decision, at any life stage: students weighing a loan, employees checking take-home pay, the self-employed facing a first tax bill, and people planning retirement. It's for anyone who wants the actual number behind a decision rather than a rule of thumb or a sales pitch.
TheBaseRate.money's answer:
It started from a simple frustration: UK money advice online is usually behind a sign-up wall, quietly out of date, or trying to sell you something. The Base Rate is the opposite. A free set of calculators, guides and short videos with one promise in the name: know the real number before you decide. Every figure is checked against the source and re-verified each tax year, and nothing is gated or tracked.
TheBaseRate.money's answer:
The Base Rate is a free tool for individuals rather than a business product, so it has no named customers. It's used by UK members of the public making their own money decisions.
