How to calculate it
The coin price is "how many USDT one coin costs", so coins = amount ÷ price. The buy fee is usually deducted from the fill, so coins received = amount × (1 − rate) ÷ price.
Unit prices differ widely: for the same 1,000 USDT you get a small fraction of a BTC but more than ten thousand DOGE.
Formulas
amount ÷ buy priceamount × (1 − fee rate) ÷ buy pricecoins × current priceWhat 1,000 USDT buys (reference prices, recompute it yourself)
| Coin | Reference price | No fee | With 0.1% buy fee |
|---|---|---|---|
| BTC | 78,400 USDT | 0.01275510 | 0.01274235 |
| ETH | 2,471 USDT | 0.40469446 | 0.40428976 |
| SOL | 102.97 USDT | 9.71156648 | 9.70185491 |
| DOGE | 0.08938 USDT | 11,188.18527635 | 11,176.99709107 |
Coins = 1,000 ÷ reference price; the fee column uses 999 ÷ reference price. Reference prices are examples; use your actual fill price.
Notes
Round or truncate to the decimals each coin uses: BTC usually keeps up to 8 decimal places; truncation introduces small errors.
1,000 USDT buys roughly 0.0127 BTC. Check the venue minimum order size and precision before ordering.
FAQ
Why does the same amount buy such different quantities?
Because prices differ: coins = amount ÷ price, so a higher coin price means fewer coins for the same amount.
Does the fee reduce the quantity, or is it charged separately?
Most venues deduct it from the fill, so the coins received are fewer. Here 1,000 USDT buys 0.01275510 BTC with no fee and 0.01274235 BTC with a 0.1% fee.
Does this match the profit calculator?
Yes. The first step there is also "amount × (1 − rate) ÷ buy price", which gives exactly this coin quantity.
