How Excelergy works
Excelergy is a suite of UK personal-finance calculators that all run in your browser. Free, anonymous, nothing you type leaves your device.
Excelergy Premium is a paid subscription (currently in private beta) that adds a cloud account on top: your figures sync across devices and across tools, you can keep named profiles for different scenarios, and a financial dashboard pulls everything together. The free calculators always stay free, with or without Premium.

How your data flows between tools
Premium feature. Shared values across the suite. How Take-Home feeds Budget, how one profile keeps everything in sync.
Two-minute quick-start
- Pick a tool. Try Take-home pay, Retirement planner, or any of the others. They all work anonymously, no account needed.
- Start a Premium trial (optional). Click Account top-right and enter your email. We send a one-time code to sign in - no password to manage. Your inputs now live in a named profile, encrypted on our server. Free during the trial; small monthly subscription after.
- Make a plan. Fill in Take-Home, hit Save. Switch to Budget - the salary row populates itself from the Take-Home figure. Switch to the Dashboard - your net worth, pension outlook and monthly cashflow are already there.
- Explore scenarios. Create a second profile called "If I take the new job" and compare. Switch between profiles from the strip under the topbar on any tool page.
Per-tool questions
Every calculator has its own FAQ for tool-specific questions - tax methodology, assumptions, edge cases. Jump straight to one:
