Slippage cost calculator
Small execution differences add up. Estimate what average slippage costs per trade, per month and per year for the way you trade or copy, and compare it with the strategy's average profit per trade.
Slippage cost per month

0.5 pips × 1 lots × 200 trades
- Per trade

- Per year

The formula
cost per month = slippage (pips) × lots × pip value per lot × fills per trade × trades per month
- Fills per trade: 1 if you only count entries, 2 if exits slip too (market closes and stops).
Worked example
A busy EURUSD source
- 0.5 pip average slippage, 1.00 lot, $10 per pip per lot.
- $5 per trade on entry only.
- 200 trades a month → $1,000 a month, $12,000 a year.
If that source's average winning trade is 5 pips, half a pip of slippage is 10% of every win. For a source with 60-pip targets, it is under 1%.
How to reduce it
- Avoid new entries during rollover and the first minutes after major opens.
- Pause around high-impact news.
- Set a maximum slippage so far-away fills are rejected.
- Skip signals that arrive late (maximum signal age).
- Compare a raw-spread account with commission against a standard account for your trade frequency.

Frequently asked questions
What is a normal amount of slippage?
On liquid forex pairs in normal hours, fractions of a pip on average, with occasional larger fills. Around news, rollover and on gold or indices it can be several pips or points.
Can slippage be positive?
Yes. Prices can move in your favour between request and fill. Over many trades, positive and negative slippage partly cancel, but on stops and in fast markets it usually works against you.

Every copied trade's latency is recorded, and max slippage and signal age filters reject far-away fills.
