Guide written .
Open the Investment purchase cost tracker calculatorWhat to prepare
- Find the relevant statement, payslip or transaction record rather than estimating from a bank balance.
- Identify the tax year, transaction date and whether each amount is gross, net, annual or monthly.
- Separate known facts from assumed rates and check eligibility against the linked official sources.
Understand the inputs
The calculation method
Sum units and purchase price plus fees; compare with current sale value after an entered fee.
Worked example
Illustrative inputs and their result.
Example inputs
- Purchases: units, unit price, fee
- 10, 100, 5 15, 120, 5
- Current unit price (€)
- 130
- Expected total sale fee (€)
- 5
Calculated example result
- Average All In Cost
- €112.40
- Unrealised Gain
- €435.00
How to interpret the result
Distinguish a tax saving, a tax bill, cash received and money remaining: they are not interchangeable. An estimate does not establish eligibility, filing compliance or when a refund will be paid.
Compare the same income or transaction under one changed assumption at a time. Keep a record of the year, date and assumptions so a change in the result can be explained.
Common mistakes to avoid
- Do not mix tax years or apply a newly announced measure to an earlier transaction.
- Avoid counting an allowance, credit, contribution or loss twice.
- Check exclusions and personal circumstances before relying on the headline result.
Assumptions and sources
Not an Irish CGT tax-basis calculation or share-identification method. Disposals, dividends and FX are excluded.
