About LedgerKit
Clear, practical financial tools for everyday UK business calculations.
A useful companion to the working day
LedgerKit exists to make everyday UK business calculations clearer. It brings VAT, CIS, gross profit, mileage and late-payment interest into one focused collection, without registration or spreadsheets.
Show the working
Each tool explains its method, shows a useful breakdown and identifies the relevant rate or tax year. Results are estimates based on your entries, not a substitute for professional judgement.
Private by design
Calculator inputs are processed in your browser. LedgerKit does not intentionally save or transmit calculation values. You decide whether to copy or print a result.
Independent and focused
LedgerKit is not affiliated with or endorsed by HMRC or GOV.UK. Official links help you check the rules. More practical tools may be added over time.
