Worked example

How much BTC does your budget buy after fees?

With a $1,000 budget, $100,000 reference price, 0.25% trading fee, 0.50% spread and $2 fixed fee, you receive about 0.00990547 BTC. The effective price is about $100,954 per BTC.

What is the difference between a fee and spread?

Fees reduce the budget available for BTC. Spread increases the execution price. Percentage fees here apply to the total budget. Effective price and premium are undefined if fees consume the budget.
