Does 0 Fee Mean Free? How to Calculate Your Total Trading Cost on Stock Futures
A 0 fee label answers one question and raises another: if the exchange charges nothing, what does the order actually cost you?
The short answer is "not zero," because your total trading cost on stock futures also includes the spread, slippage, and funding.
This guide adds up all four on a $100K order, using MEXC's current parameters and TokenInsight's simulated slippage data, so you see the whole bill before you place it.
Key Takeaways
- Total trading cost on stock futures adds up four lines: the trading fee, the bid-ask spread, slippage, and funding.
- As of September 2026, MEXC lists maker and taker fees as low as 0.00% on stock futures for eligible users, and it has treated 0 fees and 0 funding as limited-time promotions since the July 2025 launch, so check the pair's page for your rate.
- In TokenInsight's August 2026 report (weekday sample 29 July to 6 August 2026), a simulated $100K SPCXUSDT sell order on MEXC saw 0.0112% median slippage, or $11.20.
- At the 90th percentile (P90), the same order saw 0.0230%, or $23.00, and the P90 is the number to budget with.
- A hypothetical 0.05% taker fee would add $50.00 to that order, more than the P90 slippage, so on a liquid pair a non-zero fee can be the biggest line on the bill.
- Limit orders, sizing to visible depth, and avoiding thin hours keep total cost low.
What makes up your total trading cost?
Total trading cost on stock futures adds up four lines: the trading fee, the bid-ask spread you cross to get filled, the slippage between expected price and fill, and the funding paid while a position stays open.
Two of them appear on your statement; the other two hide inside your fill price.
The trading fee is a maker or taker rate charged on order value at the fill.
The spread is the gap between best bid and best ask, paid the moment a market order crosses the book.
Slippage shows up when your order is bigger than the liquidity at the best price, so part of it fills at worse levels; slippage on stock futures covers the mechanics.
Funding is a periodic payment between long and short holders that keeps a perpetual near its underlying price, paid to other traders rather than the exchange, as funding rates on MEXC futures explains.
What does MEXC charge on stock futures?
As of September 2026, the MEXC stock futures page lists maker and taker fees as low as 0.00% on US stock futures pairs, and MEXC has described 0 trading fees and 0 funding fees on stock futures as a limited-time promotion since the product launched in July 2025.
Treat both as today's parameters, not permanent ones: MEXC can change them, and the MEXC fee schedule notes that rates can vary with platform events and user region.
For eligible users, the fee line can be zero on both sides, whether you post a limit order that rests on the book (maker) or take an existing order (taker).
The funding line is a promotional parameter rather than a fixed one, so check the funding rate shown on the pair's page; when it applies, it normally settles every eight hours on a perpetual position.
Rates for other futures pairs sit on the fee schedule, and your trade history shows the exact rate charged on each fill, so look at the pair's page before you size the order and read the bill after it fills.
How much does slippage add on a $10K and a $100K order?
Very little at $10K, and more at $100K, according to TokenInsight's Equity Perpetuals Market Report.
In its 29 July to 6 August 2026 weekday sample of simulated sell orders on five centralized exchanges, every venue kept median slippage under 0.02% at $10K, and MEXC had the lowest median on SKHYNIXUSDT, SOXLUSDT, and SPCXUSDT, between 0.0008% and 0.0024%.
No P90 reading exceeded 0.035% at that order size.
At $100K, MEXC again led those three pairs on median and P90: 0.0170%, 0.0130%, and 0.0112% median, and 0.0241%, 0.0278%, and 0.0230% P90.
On SNDKUSDT and INTCUSDT, MEXC did not lead at either size, placing second and third respectively.
The median is the typical fill; the P90 is the level nine fills in ten stayed under, so budget with it.
TokenInsight Research noted that tail risk rose materially at $100K, with several venues above 0.06% at P90; our MEXC liquidity hub tracks each report.
What does a $100K SPCX order cost from start to finish?
Using MEXC's September 2026 fee parameters and TokenInsight's July to August 2026 slippage medians, a $100,000 SPCXUSDT sell order on MEXC would have cost about $11.20 on a typical fill and about $23.00 on a rough one, with the trading fee at zero for eligible users and no funding line, because funding applies only to a position held through a settlement time.
The spread is built into the fill price rather than billed as a separate line.
- Trading fee: 0.00% for eligible users as of September 2026, so $0.00.
- Spread: inside the fill, no separate line.
- Slippage, median: $100,000 × 0.0112% = $11.20.
- Slippage, P90: $100,000 × 0.0230% = $23.00.
- Funding: $0.00 on the fill itself; it applies only if you hold the position through a settlement time.
- Total: $11.20 at the median, $23.00 at the P90.
Under a hypothetical 0.05% taker fee, not a quote from any exchange, the fee line alone would be $100,000 × 0.05% = $50.00 before any slippage.
That one line exceeds the P90 slippage in this example, which is why a non-zero fee can be the biggest line on a liquid pair.
Does a full trade cost more than a single order?
Yes, because a trade is two fills, one to open and one to close, and each fill carries its own spread and slippage, so the numbers above describe one leg, not the round trip.
Any trading fee applies to both legs as well, and funding, where it is charged, accrues between them for as long as the position stays open.
Scalpers therefore watch the fee and the spread first, while anyone holding for days watches funding first.
MEXC launched stock futures in July 2025 with 0 funding fees as a limited-time promotion, so check the funding rate on the pair's page before holding through a settlement or a weekend.
Equity perpetual volume thins sharply on weekends in TokenInsight's sample, when the underlying stock market is closed, and a thin book widens your exit leg.
How do you keep total cost low?
Four habits cover most of it: post limit orders where you can, so you sit on the maker side and skip the spread; size each order to the depth you can see; read the depth chart before you trade; and stay away from thin periods, when the same order slips further.
Limit orders trade execution certainty for price certainty, the right trade when you are not in a hurry.
Sizing to depth is the cheapest fix: slippage grows with order size, as the jump from $10K to $100K shows, and splitting a large order keeps each piece inside the liquidity at the best price.
Our guide to order book depth explains how to read the book, weekend liquidity covers the hours when equity perpetuals thin out, and a glance at the funding rate on the pair's page before a settlement time rounds out the checklist.
FAQ
Is 0 fee really free?
No; a 0 fee removes the trading fee line, but the spread, slippage, and any funding still apply.
What is slippage cost?
Slippage cost is the gap between the price you expected and the average price you got, times your order size, such as $11.20 on $100,000 at 0.0112%.
What is the difference between spread and slippage?
The spread is the visible gap between best bid and best ask before you trade; slippage is the extra distance your fill travels when your order exceeds the liquidity at that price.
Is the spread a fee?
Not as a line on your statement; the spread is paid through the fill price when a market order crosses the book.
Which costs more, trading fees or slippage?
It depends on the fee rate and the order size; in this example a hypothetical 0.05% taker fee ($50.00) costs more than the P90 slippage ($23.00).
What is a funding rate?
A funding rate is a periodic payment between long and short holders that keeps a perpetual's price close to the underlying, settled on MEXC every eight hours by default.
Does MEXC charge funding on stock futures?
MEXC launched stock futures in July 2025 with 0 funding fees as a limited-time promotion, so the funding rate shown on the pair's page is what applies today.
What is the taker fee on MEXC futures?
As of September 2026, US stock futures pairs on MEXC list taker fees as low as 0.00% for eligible users; your own rate sits on the MEXC fee schedule and varies by region and event.
How do I calculate my trading cost?
Order size × fee rate, plus order size × expected slippage (the P90 for a safe budget), plus any funding for the holding period, counted on both legs; leverage tiers change how much you can open, not the arithmetic.
Conclusion
A 0 fee is a real saving; on a liquid pair it removes a line that is often the biggest.
It is not the whole bill, and the gap between $11.20 and $23.00 on the same order is why the P90 deserves a look before you size up.
The arithmetic is the same for every contract on the list, and how many stocks you can trade as perpetual futures shows what that list holds.
Check the current parameters on MEXC stock futures, run the four lines yourself, and trade with the total in front of you.
