Fees and payback
Estimate trading fees and fee payback.
Enter your values and calculate to see an estimate.
This estimate is not an account balance, credited payback or a confirmed settlement or payout. A minimum payout threshold does not reduce the estimate to zero; actual eligibility and payout conditions apply separately.
How this estimate is calculated
Trading fees F = N × [(1 − t) × m + t × k]; payback P = F × p; estimated cost = F − P. N is total executed notional, t is the Taker share, m and k are Maker and Taker rates, and p is the payback rate. The comparison uses the same mix at standard rates; savings = comparison cost − estimated cost. Percentages are converted to fractions.
Calculations retain exact decimal values internally. Final amounts are rounded half-up to 8 decimal places; displayed lines may not add up exactly after rounding. A positive result that would otherwise round to zero is explicitly marked as less than 0.00000001, not as an exact zero.
No additional VIP discount, promotion or unconfirmed exchange payback rate is assumed.
