Asset disposals often look simple until rate splits, losses and reliefs come into play.
We check whether the gain should be split between the unused basic rate band and the higher rate band.
Where relevant, we review whether a disposal may fall under BADR or standard asset CGT treatment.
You get a clearer position for reporting through Self Assessment or the real-time CGT service.
This calculator uses the current 2026/27 structure for individuals.
| Scenario | Rate |
|---|---|
| Main CGT rate within unused basic rate band | 18% |
| Main CGT rate above unused basic rate band | 24% |
| Business Asset Disposal Relief rate | 18% |
| Annual Exempt Amount | £3,000 |
Special situations such as share pooling, carried interest, trust gains, negligible value claims, corporate reorganisations and partial relief claims should be reviewed separately.

No. This page is for shares, crypto, funds and other chargeable assets, not UK residential property disposals.
Yes. You can enter losses you plan to use, and the calculator deducts them before the annual exemption.
Tick the BADR box only if the disposal genuinely qualifies. The calculator then applies 18% to the taxable gain instead of the standard 18% / 24% split.
Book a quick review and make sure the right rate, relief and losses have been applied.
