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.
- Enter your starting values once. Head to the Premium setup page and fill in salary, pension, home value, ISA and tax region. Every tool and the dashboard update automatically. You can come back and update anything later.
- Open the tools. Switch to Budget - the salary row is already populated. 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:
