Why does received quantity matter?

Fees may be charged in value or in coins; on the “fee from budget” basis, net = (budget − fee) ÷ price.

The all-in unit cost = budget ÷ net quantity, ready to compare against net sell proceeds.

How to use

  1. Enter your buy budget.
  2. Enter the buy price and per-side fee rate (%).
  3. Click Calculate for fee, gross/net quantity and all-in cost.

Formula

  • Fee = budget × rate
  • Net quantity = (budget − fee) ÷ price
  • All-in cost = budget ÷ net quantity

Example

Budget 10,000 at 20,000 with 0.1% → fee 10, net ≈ 0.4995 BTC, all-in ≈ 20,020.

Higher fees raise the premium of the all-in cost over the market price.

FAQ

Is the fee in coins or value?

Venue-dependent; this tool assumes the fee comes out of the budget value. Adjust to your venue's rules.
