What's the difference between FIFO, LIFO, and HIFO?

FIFO matches oldest lots first (often lower cost basis = more gain). LIFO matches newest lots first. HIFO matches highest-cost lots first, which minimizes reported gain. Tax authorities may restrict which you can use — check your local rules.

Does this handle short-term vs. long-term gains?

Yes. We flag each sale as short-term (held ≤ 1 year) or long-term (held > 1 year), based on the buy date of the matched lot vs. the sell date. Long-term typically has lower tax rates in most jurisdictions.

How is the tax estimate computed?

We multiply short-term gains by your short-term rate and long-term gains by your long-term rate (both editable). This is a simplified estimate — actual tax depends on your full income, jurisdiction, losses carried forward, etc.

Can I export the lot-matching detail?

Yes — the result card lists each sell's matched lots, units, cost basis, proceeds, and gain. Copy or screenshot it for your records or accountant.

Does this account for transaction fees?

Not by default. You can include fees by adding them to the price per unit on buys (increases cost basis) and subtracting them on sells (reduces proceeds).

Are my trades uploaded anywhere?

No. All calculations are local. Your trade history never leaves your browser — verify in DevTools.
