Fee-aware accuracy

Buy and sell exchange fees are factored into cost basis and proceeds, so results match what actually lands in your wallet.

Break-even finder

See the exact price your position needs to reach to cover costs and fees before you take a loss.

Realized & unrealized modes

Check profit on a trade you've already closed, or a live "what if I sold now" estimate against the current market price.

Multi-currency display

View every figure in USD, BDT, EUR, GBP or INR — switch anytime without re-entering your numbers.

Visual gain/loss gauge

A single glance at the gauge tells you how strong the win — or how deep the loss — really is.

Optional tax estimate

Add a profit-tax percentage to see a more realistic, after-tax take-home figure alongside the raw numbers.

100% client-side

Every calculation runs locally in the visitor's browser. No amounts, prices or wallets are ever sent anywhere.

Mobile-ready layout

The panels, gauge and metric grid reflow cleanly on phones and tablets, matching Blogger's responsive theme.

How to use
Get a full breakdown in six steps
1

Pick a calculation mode

Choose "By investment" if you know the fiat amount you spent, or "By quantity" if you know exactly how many coins you hold.

2

Enter your buy price

Type the price per coin at the time you bought, plus your investment amount or quantity depending on the mode above.

3

Enter the sell / current price

Use the price you sold at for a closed trade, or today's market price to preview an unrealized gain or loss.

4

Set the trade status

Toggle "Sold" for a realized trade or "Holding" for a live, unrealized estimate — the results relabel automatically.

5

Add fees & tax (optional)

Open "Fees & tax" to include your exchange's buy/sell fee percentages and, if relevant, a profit tax rate.

6

Net profit, ROI, multiplier, break-even price and total fees update instantly — copy the summary with one click.
