Who it's for

Anywhere your visitors or staff need a quick, accurate UK finance answer — a public web page or a private internal hub.

Estate agents & mortgage brokers

Give buyers an instant answer to "how much will I pay?" — an accurate stamp duty calculator on your own pages.

Accountants & finance firms

Add useful client-facing tools — tax, salary sacrifice, CGT — to your website without a developer building or maintaining them.

Employers, HR & benefits

Drop a salary sacrifice, pension or take-home calculator onto your staff intranet, benefits portal or SharePoint hub — a simple financial-wellbeing win, no IT project.

Banks, lenders & financial services

Give customers useful financial tools without sending them off to a third-party calculator. For smaller lenders, fintechs, networks and pension providers, it's an easy start — and the gateway to a custom build.

Why not just build one yourself?

You can — but a developer spends a day or two building it, and then someone has to remember to update it after every Budget. That's the real cost. We maintain the calculations centrally: We update the rates after each Budget; you don't need to change the embed.

UK rates updated centrally after each Budget (no change to your embed)
No developer time — one line of code, live in ~5 minutes
Mobile-friendly & auto-resizing on any site or intranet
No ads, and no tracking — nothing about your visitors or staff is stored
Accurate UK logic — SDLT/LBTT/LTT, HICBC, Scottish bands, allowances
Usually cheaper than the developer time to build one, let alone keep it current

Need a tool we don't have yet? We'll build it.

If your team needs a specific UK finance calculator — or an interactive benefits tool for your website or intranet — we build it in your branding, from £999. For HR & reward teams that often means a total-reward statement (each employee sees the full value of their package, not just salary), a salary-sacrifice modeller (pension, EV car scheme, cycle-to-work — so staff see the take-home impact and actually take them up), or a parental-pay or pension illustrator tailored to your own policy. Here's how custom builds work, so you know exactly what you're getting:

  • UK personal finance & employee benefits. Tax, pensions, salary sacrifice, reward & benefits, property, savings, mortgages — the areas we know deeply.
  • Illustrative tools, not regulated advice. The tool informs; it doesn't give personal recommendations. You keep your own compliance sign-off.
  • Private by design. Manual input, no bank linking, no storing your users' or employees' data — safe to place on a staff intranet.
  • Fixed scope, fixed quote. We agree exactly what it does and what it costs up front — from £999, no open-ended bills.
  • Kept current, optionally. Add an annual update so the rates refresh every UK tax year.
  • Your brand, our engine. It carries your branding; we retain the underlying calculation engine and licence it to you.

Questions

How much does it cost?

It's free to embed any available WealthR calculator, as long as you keep the small "Powered by WealthR" link. White-label (your branding instead of the WealthR link) is not available yet; you can register interest below. Bespoke calculators built for you start from £999.

Why not just build my own?

You can — but a developer will spend a day or two building it, and then someone has to remember to update it every time UK tax or financial rules change in the Budget. WealthR calculators are maintained centrally: We update the rates after each Budget; you don't need to change the embed. Usually cheaper than the developer time it would take to build one, let alone keep it current.

Can I put it on our staff intranet or benefits portal?

Yes. It works on internal intranets, benefits portals, staff hubs and SharePoint pages exactly as on a public website — paste the same code. HR and benefits teams use them so employees can model salary sacrifice, pensions and take-home without leaving the portal. The embed carries a small "Powered by WealthR" link; a bespoke build can carry your company's branding. Email partnerships@wealthr.co.uk.

Does it track our visitors or staff?

No. Embedded calculators send no analytics and set no third-party trackers — inputs stay in the visitor's browser and nothing is stored or sold. That's deliberate, and it's why they're safe to place on an employee intranet.

Can you build a custom calculator or benefits tool for us?

Yes — for UK personal finance and employee benefits (tax, pensions, salary sacrifice, reward & benefits, property, savings, mortgages), in your branding, from £999. Popular HR builds include total-reward statements, salary-sacrifice modellers and parental-pay illustrators. Custom builds are illustrative tools, not regulated advice; scope and price are fixed up front. Email partnerships@wealthr.co.uk.

How long does it take to add one?

About five minutes — pick a calculator, copy the one-line snippet, paste it into any page, CMS block or intranet page. It's lazy-loaded and auto-resizes, so there's no developer work.
