Free Crypto Record-Keeping Calculators
Record-keeping arithmetic, and nothing pretending to be tax advice
Cost basis with fees folded in, the realised result on a disposal, the difference between FIFO and average cost on the same sale, and what a year of trading fees actually costs.

This is a weighted average cost basis with fees folded in. Tax rules in some countries require FIFO, specific identification or another method instead.
The average entry price is also the break-even price before any exit costs.

These tools calculate cost basis and realised results. They apply no tax rate, assume no jurisdiction and reach no conclusion about what you owe - because those depend on rules that differ everywhere and change regularly, and a site that guessed at them would be doing harm.
What they do is produce the underlying figures accurately, including the parts most often got wrong: fees on both sides of a trade, the method used to identify which units were sold, and the difference that method makes.

Why use CryptoTaxTools
Fees counted on both sides
Acquisition fees increase the basis and disposal fees reduce the proceeds. The disposal side is the one most often forgotten.
Method comparison on one disposal
FIFO, weighted average and highest-cost-first on the same sale. On a position built across a wide price range the spread is large.
No rates, no jurisdiction, no conclusions
This is arithmetic to take to a professional, not a substitute for one. The rules governing which method applies to you are local.
Fees as an annual number
Commission and spread across a year of trading, with the break-even move each round trip has to cover.
How it works
- Establish the cost basis of each holding from your own transaction records.
- Calculate the realised result on each disposal with fees on both sides.
- Compare methods on any partial sale before assuming which one applies.
- Take the figures, and the underlying records, to a qualified tax professional.
Frequently asked questions
Do these tools calculate the tax I owe?
No. They calculate cost basis and realised gains and losses. No tax rate is applied and no jurisdiction is assumed. Nothing on this site is tax advice.
Which cost basis method should I use?
Whichever your jurisdiction requires or permits, decided with a qualified professional. Some mandate FIFO, some require a pooled average, and some permit specific identification only with adequate records.
Is a crypto-to-crypto swap a taxable disposal?
In many jurisdictions yes, in some no. It is exactly the kind of question that needs local guidance rather than a general answer from a calculator.
Do you store or upload my transaction data?
No. Every calculation runs in your browser. Nothing you enter is transmitted, stored or associated with you in any way.
Can I use these tools for shares?
The arithmetic is identical. The tax treatment frequently is not, and in several jurisdictions crypto is treated quite differently from shares.
