How to Read a Broker's Spread and Commission Schedule
Learning to read a broker's spread and commission schedule honestly is the single most useful skill for keeping your trading costs under control — because the numbers on a marketing page rarely match what actually hits your account. Most schedules are written to look competitive, not to be easily compared, so this guide shows you how to strip away the marketing and work out what a trade genuinely costs.
Why Spread and Commission Schedules Are Easy to Misread
Broker fee pages are designed to highlight the best-case scenario. A few things make them tricky to read at face value:
- "From" figures — a spread listed as "from 0.0 pips" is a floor, not an average. It might occur for a few milliseconds a day.
- Account-type confusion — the same broker often publishes different spreads for standard, raw, and VIP accounts, and it's easy to compare the wrong pair of numbers.
- Commission left out of headline pricing — some pages lead with the spread and bury the commission in a separate table or PDF.
- Currency of the commission — commission quoted per lot in USD isn't the same as per lot in your account currency, especially if you trade in GBP.
- Time-of-day averages — a "typical" spread is usually calculated during liquid London/New York hours, not the Asian session or around rollover.
None of this means a broker is being dishonest, but it does mean the reader has to do some work. Treat every published number as a starting point for verification, not a finished answer.
Breaking Down the Two Cost Components
To read a schedule properly, separate it into its two parts and understand what drives each one:
Spread - The difference between bid and ask, quoted in pips or points. - Built into the price — you don't see it as a separate charge on your statement. - Varies by instrument: majors are usually tighter than minors and exotics. - Can be fixed (rare now) or variable/floating (the norm on most retail accounts).
Commission - A stated fee, usually per lot per side (e.g., charged on opening and again on closing). - Common on ECN/raw-spread accounts alongside a much tighter spread. - Sometimes tiered by monthly volume — higher volume can mean lower per-lot commission. - Always check whether the quoted figure is per side or round turn, as this doubles or halves your real cost depending on which convention the broker uses.
Once you know which components apply to your account type, you can start combining them into a single comparable figure.
Turning Both Numbers Into One Honest Total
The only fair way to compare brokers is to convert everything into a total cost per round-turn trade, in your own account currency, for the size you actually trade. A simple method:
1. Take the spread in pips and convert it to a monetary value for your lot size (pip value × spread). 2. Add the commission for both the open and close, converted to your account currency if needed. 3. Divide by your typical position size so you get a cost per standard lot, making brokers directly comparable. 4. Repeat for at least two account types at the same broker, since the "cheapest" one depends on your trade frequency and size.
For example, when comparing Pepperstone's Standard vs Razor account structure, the Standard account rolls commission into a wider spread, while Razor charges a lower spread plus a separate per-lot commission — the cheaper option depends entirely on your volume. Similarly, IG's own platform pricing and its MetaTrader offering can carry different spread structures for the same underlying pair. Neither broker's headline numbers should be taken as final — run your own trade size through the numbers, or better, through a live tool.
Reading the Fine Print That Actually Matters
Beyond the headline spread and commission, the fine print usually holds the details that affect your real cost most:
- "Average" vs "minimum" vs "typical" — these words are not interchangeable and the schedule should define which one it's using.
- Spread widening conditions — around high-impact news, market open/close, and rollover, spreads can widen well beyond the quoted average.
- Commission tiers and rebates — some brokers reduce commission after a volume threshold; check if that applies to your realistic monthly turnover, not an aspirational one.
- Minimum trade size effects — commission structured per lot can distort cost percentage for very small trades.
- Account currency conversion — if your account is in GBP but commission is quoted in USD, a conversion fee may apply on top.
Reading these details takes minutes and often changes the entire comparison, especially for active traders.
Other Costs That Belong in the Same Comparison
An honest cost comparison doesn't stop at spread and commission. Two accounts with identical trading fees can still produce very different bills once you factor in:
- Swap/rollover rates — charged for positions held overnight, and they vary significantly by instrument and direction (long vs short).
- Inactivity fees — charged after a period of no trading, relevant if you trade infrequently.
- Withdrawal and deposit fees — some payment methods carry charges that erode any spread savings.
- Currency conversion fees — applied if you fund or withdraw in a currency different from your account base currency.
None of these appear on a standard spread/commission table, but they belong in your total cost of trading. Check /rates.html for current swap information relevant to your instruments before assuming a "cheap" spread makes the whole account cheap.
A Practical Checklist Before You Compare Brokers
Use this checklist every time you sit down to compare a spread and commission schedule:
- [ ] Confirm the account type the schedule applies to (standard, raw/ECN, VIP).
- [ ] Note whether the spread figure is "from," "average," or "typical," and over what time window.
- [ ] Check if commission is per side or round turn, and in which currency.
- [ ] Calculate total cost per lot for your actual trade size, not the example used in marketing.
- [ ] Add swap costs if you hold trades overnight.
- [ ] Factor in withdrawal, deposit, and inactivity fees if relevant to your trading style.
- [ ] Recheck the numbers periodically — schedules change without much notice.
Doing this once for each broker you're considering, rather than trusting the front page, is the difference between an assumption and a genuinely honest comparison.
Conclusion: Make the Schedule Work for You, Not the Marketing Copy
Learning to read a broker's spread and commission schedule honestly means treating every published figure as a starting point, not a guarantee — convert spread and commission into one total cost, check the fine print on averages and widening, and add swaps and account fees before drawing any conclusions. Trading costs compound over time, and even small differences per lot add up across hundreds of trades, so it's worth the extra ten minutes. For live, up-to-date numbers rather than static marketing pages, run your own trade sizes through PipTax's cost tool at /audit.html, and compare account structures side by side at /brokers/index.html.
Key takeaways
- A spread and commission schedule only tells the truth if you read the fine print — 'from' figures are typically best-case, not typical.
- Always convert spread + commission into a single per-round-turn cost in your account currency before comparing brokers.
- Raw/ECN accounts with commission can be cheaper than 'zero-commission' standard accounts once total cost is calculated properly.
- Widening happens around news events and rollover — check if the published spread is an average, a minimum, or a typical figure.
- Swap rates, inactivity fees and withdrawal charges belong in the same honest comparison as spreads and commission.
- Use a live cost tool rather than marketing pages, since published schedules change and vary by account type and instrument.
Frequently asked questions
- What's the difference between spread and commission?
- The spread is the gap between the bid and ask price, built into the price itself. Commission is a separate, explicit fee charged per trade or per lot, usually on ECN/raw-spread accounts. Some accounts charge only spread, some charge a smaller spread plus commission — you need both numbers to compare fairly.
- Why do two brokers quote different spreads for the same pair?
- Liquidity sourcing, account type, and markup all differ. A standard account usually has spread markup built in with no commission, while a raw account passes through the interbank spread and charges commission separately. Time of day and volatility also affect the spread you actually get, not just the advertised one.
- Is a 'zero commission' broker always cheaper?
- Not necessarily. Zero-commission accounts almost always have wider spreads to compensate. You need to add spread cost and commission together for a like-for-like comparison rather than assuming no commission means no cost.
- How often do spreads change?
- Spreads float constantly with market liquidity and volatility. Published 'typical' or 'average' spreads are usually calculated over a period during normal market hours, so they can be tighter than what you see during news releases, rollover, or thin overnight liquidity.
- Where can I check real, current costs instead of marketing figures?
- Use PipTax's cost tool at /audit.html to see live spread and commission data pulled from broker feeds, and check /brokers/index.html for account-type breakdowns before you compare on your own trade sizes.
