HOW THE CALCULATOR WORKS
Understanding the BADR Calculator UK Tool
Our BADR calculator UK tool gives you a fast, reliable estimate of the Capital Gains Tax due when claiming Business Asset Disposal Relief (formerly Entrepreneurs’ Relief). Simply enter your disposal proceeds, base cost and allowable expenses, and the calculator applies the reduced 18% BADR rate up to the £1 million lifetime limit.
The calculator deducts your original cost and expenses from the sale proceeds, applies the flat rate to the qualifying gain, then uses the standard higher CGT rate on anything above the lifetime limit, so you can see exactly how much Business Relief you’re entitled to. For the official rules, see HMRC’s guidance on Business Asset Disposal Relief.
BADR can also apply to disposals of partnership interests and sole trader businesses, not just company shares. You may also find our general Capital Gains Tax calculator useful for comparing outcomes. If you’re planning a sale, our BADR and Entrepreneurs’ Relief service can help confirm your eligibility before you report to HMRC.

BADR Calculator UK: Frequently Asked Questions
Business Asset Disposal Relief charges Capital Gains Tax at a flat rate of 18% on qualifying gains, up to a lifetime limit of £1 million. Without the relief, higher and additional rate taxpayers would otherwise pay 24% CGT on the same gain.
You can claim BADR on qualifying gains up to a cumulative lifetime limit of £1 million. This limit applies across all claims made over your lifetime, not per transaction, so it's worth tracking previous claims carefully.

Yes, the calculator works for qualifying disposals of shares in a personal company as well as sole trader businesses and partnerships, provided you meet the shareholding and trading company conditions.

Yes, you can claim BADR on multiple qualifying disposals throughout your lifetime, as long as your combined claims don't exceed the £1 million lifetime limit. Each disposal must independently meet the qualifying conditions.
