Capital Gains Tax feels much simpler when you can see the full breakdown in one place. That’s why we created our Capital Gains Tax Calculator.
It gives you a simple estimate when you’re selling or gifting assets such as:
• Shares
• Investments
• Property
• Cryptocurrency
• Business assets
• Personal possessions
You add the key details.
The calculator shows the breakdown.
→ Sale price
→ Purchase price
→ Allowable costs
→ Annual CGT allowance
→ Taxable gain
→ Estimated tax due
You don't need to go through complicated spreadsheets.
Just a clearer way to understand what the numbers mean before you speak with your accountant or tax adviser. You can also download a PDF summary of your calculation, which is useful for keeping records or reviewing the figures later.
At Your Company Formations, we’re building practical tools to make company admin, tax planning and business decisions easier for UK founders, directors and business owners.
