Slippage Calculator
Calculate the exact cost of slippage on any trade. In pips, in dollars, and as a percentage of your intended P&L. Type the price you wanted to fill at, the price your broker actually filled at, and the calculator returns the dollar damage plus a cost projection over 100, 500, and 1000 future trades. Works on forex, crypto, stocks, commodities and indices. With cross-currency conversion and JPY pip math handled automatically.
Why slippage happens: liquidity gaps, news prints, broker latency
Pick the instrument type (forex, crypto, stocks, commodities, indices), search the symbol, choose Buy or Sell, set lot size, then type the price you intended to fill at and the price your broker actually filled at. Hit Calculate and the six panels below appear. Net slippage cost, R:R impact, cost projection across future trades, multi-trade audit, forensic exports, and AI execution review.
1. Net slippage cost : in pips and in dollars
The top of the results panel surfaces the four numbers that matter for every fill: Slippage in pips/points (the raw price difference between your intended fill and the actual fill, sign-corrected for Buy vs Sell), Slippage in dollars (the same number multiplied by pip value and lot size, in your account currency), Verdict (Negligible / Acceptable / Costly / Severe. Colour-coded), and Broker grade (A+ / A / B / C / D / F based on the magnitude). The math handles JPY 0.01 pip size, cross-currency triangulation when the quote isn’t your account currency, and stock/crypto contract sizes automatically.

2. Multi-trade audit : average slippage across your history
One trade tells you the slippage on that fill. One hundred trades tells you whether your broker is robbing you. Pro lets you paste your full MT4/MT5 trade history (or upload a CSV) and the calculator audits every fill: mean slippage, worst-case, total dollar leakage, and which symbols/sessions get the worst fills. CleaRank Pro unlocks the audit view; free users calculate one trade at a time.
3. R:R impact : how slippage erodes your edge
Most traders ignore slippage because the per-trade hit looks small. But slippage doesn’t just cost dollars. It degrades your risk-to-reward. A 1.5:1 setup with 2 pips of adverse slippage on entry becomes 1.3:1 in practice. Over 100 trades, that’s the difference between a profitable system and a break-even one. Add your stop-loss and take-profit prices into Advanced inputs and the calculator shows intended R:R vs actual R:R side-by-side, plus the win-rate increase you’d need to recover the lost edge.

4. Cost projection : what slippage costs you over 1,000 trades
3 pips per trade looks negligible. Multiply by 100 trades and you’ve lost $3,000 on a 1-lot strategy. Multiply by 500 trades and you’ve lost $15,000. The entire profit of a winning year, gone to fills. The cost projection card extrapolates your current slippage rate across 100 / 500 / 1,000 trades so you can see exactly what your broker’s execution quality costs you per year. Spoiler: it’s almost always more than the spread.
5. Forensic exports : PDF, CSV and JSON of every audit
An audit you can’t cite is an audit nobody acts on. Pro exports the full forensic result as a timestamped PDF (for broker complaints), CSV (for your trade journal or accountant), and JSON (for your own analysis or feeding into another tool). Every fill, every adverse pip, every dollar cost. Signed, dated, and reproducible. CleaRank Pro unlocks the export bundle; free users see the audit on-screen.

6. AI execution review : is your broker stealing from you?
CleaRank Financial AI reads your full MT4/MT5 fill history. Symbol, session, broker, intended vs actual prices, and delivers a four-block forensic verdict: Execution Quality grade (A+ → F based on adverse-fill magnitude), Pattern Detection (where slippage clusters by session, symbol, or news event), Broker Comparison (your fills vs ECN median benchmarks), and the three Action Plan items that recover the most edge. Particularly useful when adverse fills feel “random”. The AI surfaces the structural pattern your broker hopes you never see.
Bid-ask spread vs slippage cost: separating the two killers of edge
Scalpers, swing traders, news traders, prop-firm challengers. The slippage math is the same idea but the consequences differ. A 1-pip fill miss is rounding noise on a 200-pip swing, and the difference between pass and bust on a 5-pip scalp. Pick the workflow that matches yours.
Scalpers & HFT
When your target is 5–10 pips, 1 pip of slippage cuts 10–20% off your reward instantly. The calculator quantifies the per-trade hit and projects it across 1,000 fills to expose the broker that’s quietly eating your edge.
Swing & multi-broker traders
Trading the same pair across two brokers? Drop both fill histories into the audit and the side-by-side broker comparison tells you which one is honest and which one is taking the other side of every trade.
News & event traders
NFP, FOMC, ECB. Slippage on news prints can be 5–100 pips. The calculator separates calm-session slippage from news slippage so you can decide whether trading the headlines actually pays after the broker takes its cut.
Prop-firm challengers
funded-account programs, MyFundedFX, funded-account programs. One bad-broker challenge is the difference between a payout and a bust. Audit your fills before you start so a hidden slippage tax isn’t the reason you fail the daily loss limit.
Cost projection: how slippage compounds over 100, 500, 1000 trades
Most “slippage calculators” online ask for slippage in pips and multiply by a generic pip value. Ignoring JPY pip size, ignoring cross-currency conversion, ignoring stock/crypto contract sizes. The dollar number they hand back is off by 30–50% on anything other than a USD-account EUR/USD fill. This slippage calculator handles the math properly: JPY pairs use 0.01 pip with live cross-rate conversion, GBP/AUD on a USD account triangulates through GBP/USD + AUD/USD, gold uses $0.01 per ounce with 100-oz contracts, BTC scales by coin size. On top of accurate numbers you get a cost projection across 100/500/1,000 trades, R:R degradation analysis, and a broker grade A+→F. All from two prices, every asset class, no login.

Broker grade by slippage profile: tight, normal, wide, abusive
Slippage is the difference between the price you intended to fill at and the price your broker actually filled at. On a market order, it’s the gap between the price you saw when you clicked Buy and the price that landed in your account. On a limit order, slippage is zero by definition (the broker either fills at the limit or doesn’t fill). Positive (adverse) slippage means you paid more on a Buy or sold lower on a Sell. Bad for you. Negative (favourable) slippage means you filled better than expected. Rare on retail accounts but possible during low-volatility windows. The reason slippage is the “silent killer” is that 1 pip of adverse slippage on a 20-pip scalp is a 5% direct hit on your reward. Multiply across 100 trades a month and that’s 60% of your annual edge eaten by execution quality.
“Slippage is the spread you can’t see. Most traders pretend it doesn’t exist because the per-trade hit is small, and most of them lose an entire winning year to it by the time December lands. The math takes 30 seconds. The audit takes ten minutes. The fix is usually a different broker.”
The slippage formula, in plain English
Slippage in pips = (Actual Fill Price − Intended Fill Price) ÷ pip_size, sign-corrected by direction. For a Buy, a positive result is adverse (you paid more); for a Sell, a positive raw difference is favourable (you sold higher). The calculator applies direction_sign = +1 for Buy, -1 for Sell so the displayed value is always “cost” in pips. Positive = bad, negative = good.
Slippage in dollars = slippage_pips × pip_value × lot_size. Example: EUR/USD Buy 1 lot, Intended 1.0800, Actual 1.0803. Slippage = (1.0803 − 1.0800) / 0.0001 = 3 pips adverse. Cost = 3 × $10/pip × 1 lot = $30 lost to slippage on a single trade. Project across 100 trades = $3,000. The difference between a winning and losing system.
Example: 3-pip adverse fill × $10 pip-value × 1 lot = −$30 per trade. Direction sign flips for Sell. JPY pip size 0.01 auto-applied.
Worked example : slippage cost across 4 instrument types
Same forensic question (how much did slippage actually cost?), four asset classes. Each card shows the side, the intended-vs-actual price gap, the pip / point / share / coin conversion, and the dollar damage. Note how the calculator adapts to JPY 0.01 pip size, US stock cents-per-share, and crypto fractional-coin sizes automatically. You never have to switch tools.
Notice how the dollar cost varies wildly by instrument even with similar percentage slippage. A 3-pip slip on EUR/USD = $30; a 4-pip JPY slip on USD/JPY = $26.67; 5¢/share on AAPL = $5; a 0.05% slip on a half-BTC position = $15. The percentage hit on intended reward is what actually matters. That’s the number that tells you whether the trade still has positive expectancy after the broker takes its bite.
Slippage benchmarks : what’s “normal” by broker type & market
What’s a “good” amount of slippage? It depends on the market, the time of day, and the broker type. ECN brokers (raw spread + commission) should deliver near-zero slippage in calm sessions; market makers (spread-only) routinely add 0.5–1.5 pips of structural slippage. News and the first 5 minutes of London/NY opens are the worst. Expect 2–5x normal slippage. Match your fills to the benchmarks below to know if your broker is fair, slow, or stealing.
Bands reflect industry-typical adverse slippage ranges compiled from public broker disclosures and standard trader-survey data. Your broker grade ranks your fills against these bands. If you consistently exceed the “ECN calm” band on EUR/USD, you’re likely on a market-maker route.
Five slippage mistakes that quietly burn your account
Every trader has made these. The expensive ones make them every week and only spot the bleed when the equity curve doesn’t match the journal.
Assuming $10 per pip everywhere
“$10 per pip” only holds for EUR/USD-style pairs on a USD account. USD/JPY is $6.67. EUR/GBP from a USD account is ~$13. Use the wrong pip value and your stop-loss is calibrated to the wrong dollar risk on every trade.
Forgetting JPY pip is 0.01, not 0.0001
USD/JPY moves from 150.00 to 150.01 = 1 pip, not 100 pips. Misread the decimal and your “10-pip stop” is actually 1,000 pips wide. Meaning the trade is essentially un-stoppable until margin runs out.
Ignoring the cross-rate on non-USD pairs
EUR/GBP, AUD/NZD, GBP/JPY. None of these has USD in them, so a USD account needs a triangular conversion to get the real $/pip. Eyeballing it is off by 5–15%. The calculator pulls the live cross every refresh.
Mixing up lots and units
Skipping the triangular cross-rate conversion. A USD/JPY profit on a EUR account requires JPY → USD → EUR. Two steps, not one. Manual math that does only the first step is 5-15% off on volatile days. The calculator handles the chain automatically.
Using pips for gold and oil
XAU/USD doesn’t have “pips” the same way EUR/USD does. Gold uses $0.01 per ounce per contract. Oil futures use $0.01 per barrel per contract. Treat them like forex pips and your risk math will be 10× off.
