How to Read a Broker's Spread and Commission Schedule
Knowing how to read a broker's spread and commission schedule honestly is the difference between picking a broker on marketing copy and picking one on real, comparable cost. Most schedules are technically accurate but presented in a way that flatters the broker — this guide shows you how to strip that away and see what you'll actually pay.
Why Spread and Commission Schedules Are Easy to Misread
Broker fee pages are marketing documents first and disclosure documents second. That's not necessarily dishonest, but it means the numbers are chosen to look good, not to be easy to compare.
Common ways schedules mislead without technically lying:
- Headline "from" figures. "Spreads from 0.0 pips" describes a rare best-case moment, not a typical trade.
- Mixing account types on one page. A commission-free spread sits next to a raw-spread-plus-commission figure with no clear total.
- Averages instead of live data. Some schedules show a historical average that can be well below what you'll see during your actual trading hours.
- Omitting session context. Spreads during the London/New York overlap differ hugely from the Asian session, but the schedule often shows one number.
None of this means the broker is lying — it means the schedule needs interpreting, not just reading.
Step 1: Identify the Account Type Behind Every Number
Before comparing any figures, confirm which account tier they belong to. The same broker often runs several models side by side:
- Standard / all-in spread accounts — commission is built into the spread.
- Raw / ECN / Zero accounts — tighter spread, separate per-lot commission.
- VIP or professional tiers — lower costs unlocked by volume or professional client status.
If you're comparing Pepperstone's Standard account to IG's commission-based share CFD account, for example, you're not comparing like with like until you convert both to a single all-in cost per lot. Always check which tier a published figure refers to — it's usually in small print above or below the table.
Step 2: Convert Everything to a Single "All-In" Cost
This is the core skill. Whatever the schedule's format, reduce it to one number: total cost per standard lot, in your account currency, for the pair you actually trade.
1. Take the spread in pips and convert it to money using the pair's pip value for one lot. 2. Add any commission charged per lot (remember commission is often quoted per side, so double it for a round turn). 3. Add or note swap costs separately if you hold overnight. 4. Repeat for the second broker using the same pair, lot size, and ideally the same time of day.
Doing this by hand for every pair you trade is tedious and the inputs go stale quickly, which is exactly why PipTax built a [cost audit tool](/audit.html) — it applies this conversion using live data so you're comparing outcomes, not marketing pages.
Step 3: Check What the Schedule Doesn't Mention
An honest read of a spread and commission schedule also means noticing what's absent. Ask about:
- Swap/rollover rates — usually a separate rates page, and they move with interest rate policy.
- Inactivity and withdrawal fees — rarely on the trading-cost page at all.
- Minimum commission per trade — can make small lot sizes disproportionately expensive.
- Slippage on market orders — not a fee, but it behaves like one in fast markets.
- Guaranteed stop premiums, if you use them.
None of these are hidden in a sinister sense — they're just filed elsewhere. Check a broker's [rates page](/rates.html) and full terms alongside the headline schedule before assuming you have the full picture.
Step 4: Compare Across Sessions, Not Just Once
A schedule captured at 3pm London time and one captured at 3am can tell two different stories about the same broker. If you trade a specific session — say, the New York open or the Asian range — check spreads during that window specifically, not just whatever the schedule happens to show.
Practical approach:
- Note your typical trading hours for the pairs you use most.
- Check live spreads during those hours across the brokers you're considering, more than once.
- Watch for widening around news events — schedules never show this, but it can dominate your real costs if you trade the news.
This is also why a static PDF, however well presented, is a snapshot rather than a promise.
Step 5: Use a Cost Tool Alongside the Schedule
The most reliable way to read a broker's spread and commission schedule is to treat it as a starting point, then verify with live, comparable data. A published schedule tells you the broker's stated policy; a cost tool tells you what that policy translates to for your actual trade size, pair, and timing.
At minimum, before opening an account:
1. Pull the current schedule from the broker's own site. 2. Run the same pair and lot size through PipTax's [cost audit tool](/audit.html). 3. Check the [cost-impact calculator](/cost-impact.html) to see what the difference means over a year of your typical volume. 4. Cross-check against listed brokers on the [broker comparison page](/brokers/index.html).
Small per-lot differences compound fast for active traders, so this step is worth the ten minutes it takes.
Bringing It Together
Reading a broker's spread and commission schedule honestly isn't about catching brokers out — it's about converting marketing-friendly numbers into a single, comparable, all-in cost for the way you actually trade. Identify the account type, do the pip-to-money conversion, check what's missing from the page, compare across sessions, and confirm everything with live data before you commit. For the full breakdown of how PipTax calculates and verifies these figures, see our [methodology page](/methodology.html) — and if you want a structured next step, our [trading school](/school/index.html) covers cost management alongside strategy. Trading involves risk regardless of how competitive a broker's costs are, so treat any cost comparison as one input among several, not a guarantee of results.
Key takeaways
- A spread and commission schedule only tells the truth when you read it alongside execution type, account tier, and typical liquidity conditions.
- "Raw spread + commission" and "all-in spread" accounts can cost the same or wildly differently — always convert both to a per-lot, per-currency-pair cost before comparing.
- Advertised 'from 0.0 pips' figures are best-case marketing numbers, not what you'll pay during average trading hours.
- Swap rates, inactivity fees, and withdrawal charges rarely appear on the headline schedule but affect real returns just as much.
- Use a live cost tool rather than a PDF schedule, because spreads move with liquidity and the printed page goes stale fast.
- Compare like-for-like: same instrument, same lot size, same time of day, across at least two brokers before deciding.
Frequently asked questions
- What's the difference between a spread-only account and a spread-plus-commission account?
- A spread-only account builds the broker's fee into the bid/ask gap, so you see one number. A spread-plus-commission account (often called ECN or Raw) shows a tighter spread but adds a separate per-lot fee. Neither is automatically cheaper — you have to add the two together and compare the total to the spread-only figure for the same pair and size.
- Why do two brokers quote such different spreads for the same pair?
- Spreads depend on the liquidity providers behind the broker, the account type, the time of day, and how the broker manages its own risk (market-making vs. straight-through processing). This is exactly why a printed schedule needs context — check the account tier and trading session the numbers refer to.
- Are commissions always worse than a wider spread?
- Not necessarily. For high-volume or short-term traders, a low raw spread plus a fixed commission can work out cheaper than a wider all-in spread, especially on major pairs. For occasional or larger discretionary trades, an all-in spread account can be simpler and sometimes cheaper. Run the numbers for your own typical trade size.
- Where do swap and rollover fees fit into a spread and commission schedule?
- They usually don't — swaps are listed separately, often on a different page or PDF, and they change with central bank rates. If you hold positions overnight, check swap rates alongside spreads and commissions, not instead of them.
- How often do brokers update their spread and commission schedules?
- It varies. Some update PDFs quarterly, others monthly, and live spreads change tick by tick with market conditions. A static schedule is a starting point, not a guarantee — always confirm current figures with a live cost tool before relying on them.
