A few useful things to know.
Is LedgerKit free to use?
Yes. All eighteen tools are free and require no account or subscription.
Are my calculations saved?
No. Inputs and results are held only in the current browser page. Refreshing or leaving clears them. You can copy or print a result yourself.
How often are rates reviewed?
Each tax-based tool shows its configured rates and last-checked date. We review rates when updating the site; there is no live connection to HMRC or the Bank of England. Check the linked official guidance before relying on a result.
Do these results replace an accountant?
No. These are practical estimates, not personalised accounting, tax or legal advice. A qualified professional can consider your circumstances.
Is LedgerKit connected to HMRC?
No. LedgerKit is independent and is not affiliated with or endorsed by HMRC or GOV.UK.
