Module 1 – Forex Foundations
Lesson 1.10
How Forex Profits and Losses Are Calculated
Estimated Reading Time: 12 Minutes
Difficulty: Beginner
Why This Lesson Matters
In the previous lessons, you learned several important concepts:
Currency pairs
Pips
Lots
Leverage
Margin
You now understand how Forex trades are quoted, how price movement is measured, and how trade size affects exposure.
The next question is obvious:
How do traders actually make or lose money?
This lesson connects everything you have learned so far and shows how Forex profits and losses are calculated in a simple, practical way.
Once you understand this lesson, many Forex calculations that previously looked confusing will become much easier.
Learning Objectives
By the end of this lesson, you should be able to:
Understand how Forex profits and losses are calculated.
Explain the relationship between pips and lot size.
Estimate profit or loss from a trade.
Understand why the same pip movement can produce different results.
Avoid common beginner calculation mistakes.
Introduction
Imagine two traders.
Both buy EUR/USD.
Both experience a 20-pip price increase.
However:
Trader A makes $20.
Trader B makes $200.
How is that possible?
Because profit and loss depend on two things working together:
Pip movement
Lot size
Pips tell you how far the market moved.
Lots tell you how much currency you traded.
Combining these two factors determines your financial result.
The Basic Formula
The simplest way to think about Forex profit is:
Basic formula
Profit or loss = Pip movement × Pip value
Pip movement measures how far price moved; pip value depends mainly on your lot size.
For now, we do not need advanced broker formulas.
We only need to understand the relationship between movement and trade size.
A Simple Example
Suppose you buy EUR/USD at:
1.1000
Later, the price rises to:
1.1020
The difference is:
20 pips
If each pip is worth $1, then:
20 × $1 = $20 profit
If each pip is worth $10, then:
20 × $10 = $200 profit
The market moved the same distance.
The pip value changed because the lot size changed.
Why Lot Size Changes Profit
Different lot sizes usually have different pip values.
Table 1.10.1 — Approximate Pip Values
Lot Size | Approximate Pip Value |
|---|---|
Standard Lot (100,000) | ~$10 per pip |
Mini Lot (10,000) | ~$1 per pip |
Micro Lot (1,000) | ~$0.10 per pip |
Nano Lot (100) | ~$0.01 per pip |
These values vary slightly depending on the currency pair and account currency, but they are excellent learning approximations.
Example 1: Micro Lot
You trade 1 micro lot.
The market moves 25 pips.
Approximate pip value:
$0.10
Calculation:
25 × $0.10 = $2.50
Profit:
$2.50
Example 2: Mini Lot
You trade 1 mini lot.
The market moves 25 pips.
Approximate pip value:
$1
Calculation:
25 × $1 = $25
Profit:
$25
Example 3: Standard Lot
You trade 1 standard lot.
The market moves 25 pips.
Approximate pip value:
$10
Calculation:
25 × $10 = $250
Profit:
$250
Notice that the market movement was identical in all three examples.
Only the lot size changed.
Losses Are Calculated the Same Way
Suppose you buy EUR/USD and the market moves 20 pips against you.
With a mini lot, the calculation is:
20 × $1 = $20 loss
With a standard lot:
20 × $10 = $200 loss
This is why large lot sizes can become dangerous.
Losses grow just as quickly as profits.
A Comparison
Table 1.10.2 — Same Market Movement, Different Lot Sizes
Lot Size | 20-Pip Gain | 20-Pip Loss |
|---|---|---|
Micro Lot | +$2.00 | −$2.00 |
Mini Lot | +$20.00 | −$20.00 |
Standard Lot | +$200.00 | −$200.00 |
This table shows why beginners should pay close attention to lot size.
Where Leverage Fits In
A common misunderstanding is that leverage directly creates profit.
Not exactly.
Leverage allows you to control a larger position.
A larger position usually means a larger lot size.
The larger lot size increases the pip value.
The pip value increases the potential profit and the potential loss.
This is why leverage and risk management are closely connected.
Real-World Example
Imagine two traders each have $500.
Trader A uses a micro lot.
Trader B uses a standard lot through high leverage.
The market moves 30 pips against both traders.
Trader A loses a relatively small amount.
Trader B loses a very large amount.
The market did not treat them differently.
Their position sizes were different.
Nigerian Perspective
Many Nigerian beginners focus on how much they can make from one trade.
A better question is:
How much can I safely lose?
Professional traders usually choose lot sizes based on acceptable risk, not on desired profit.
For example, a trader may decide:
“I am willing to risk only 1% of my account on this trade.”
That decision determines the lot size.
This approach is far more sustainable than choosing the largest possible trade.
The Cost of This Mistake
Choosing Lot Size Based on Desired Profit
A beginner may think:
“I want to make $100 today.”
Then increase the lot size until the potential profit looks attractive.
Unfortunately, the potential loss increases by the same amount.
Better Habit
Choose lot size based on risk, not on profit targets.
Protecting your account is more important than maximizing a single trade.
FX Mentor Insight™
The market pays disciplined traders over time, not ambitious traders overnight.
FX Mentor Principle™ #36
Calculate your risk first. Calculate your profit second.
Lesson Summary
Forex profits and losses are determined by:
Pip movement
Pip value
Pip value is heavily influenced by lot size.
Larger lot sizes produce larger profits and larger losses from the same market movement.
Understanding this relationship is essential before risking real money.
This lesson completes the core mathematical foundation of Module 1.
