About CalcIt
CalcIt provides free, accurate UK financial calculators -- from VAT and stamp duty to mortgage overpayments, redundancy pay, and more.
Our Mission
UK tax and financial calculations should not require a spreadsheet, a subscription, or a phone call to your accountant. CalcIt exists to make common UK financial calculations accessible, understandable, and instant.
Whether you are buying a house, checking your VAT, planning a mortgage overpayment, or estimating your redundancy entitlement, our calculators give you clear, up-to-date answers in seconds.
Privacy by Design
Every calculation on CalcIt runs entirely in your browser. Your numbers are never sent to a server, never stored in a database, and never shared with anyone. There is no account to create and no data to hand over. We use privacy-focused, cookie-free analytics to understand site usage without tracking individuals.
Accuracy
Our calculators are built against current HMRC rates, thresholds, and rules for the 2025/26 and 2026/27 tax years. We update them when rates change so you always get relevant results. That said, calculators are for estimation and illustration -- always consult a qualified professional for decisions that matter.
Who We Are
CalcIt is built and maintained by a UK-based team with a background in technology and infrastructure. We believe useful tools should be free, fast, and private.
Part of a Family
CalcIt sits alongside other UK financial tools we build:
- UKPaycheck -- UK salary and take-home pay calculator
- ReadTheManual -- technology guides, tutorials, and career resources
