Investing in stocks, ETFs, cryptocurrency, or any financial asset requires a clear understanding of your true cost basis and capital gains. Many investors only focus on buying and selling prices, but forget to include important factors like brokerage fees and transaction costs. This is where an Adjusted Cost Base Calculator (ACB Calculator) becomes essential.
<Adjusted Cost Base Calculator
The ACB Calculator helps investors accurately determine:
- Total investment cost (Adjusted Cost Base)
- Cost per unit of asset
- Total sale proceeds
- Capital gain or loss
Whether you are a beginner investor or a professional trader, this tool helps you make informed financial decisions and understand your real investment performance.
What Is Adjusted Cost Base (ACB)?
The Adjusted Cost Base (ACB) is the total cost of acquiring an investment, including:
- Purchase price of assets
- Number of units purchased
- Brokerage or transaction fees
It represents the true cost of ownership per unit of an investment.
Why ACB Is Important?
Understanding ACB is crucial because it helps you:
- Calculate accurate capital gains or losses
- Avoid tax miscalculations
- Track real investment performance
- Make smarter buying/selling decisions
- Maintain proper financial records
Without calculating ACB correctly, investors may overestimate profits or underestimate losses.

ACB Calculation Formulas Explained
Understanding the formulas helps investors verify results and improve financial knowledge.
1. Total Cost (Adjusted Cost Base)
Formula:
Total Cost = (Purchase Price × Number of Units) + Fees
This gives the total amount invested in the asset.
2. ACB per Unit
Formula:
ACB per Unit = Total Cost ÷ Number of Units
This shows the true cost of each unit including fees.
3. Total Sale Proceeds
Formula:
Proceeds = Sell Price × Units Sold
This is the total amount received from selling assets.
4. Cost of Sold Units
Formula:
Cost of Sold Units = ACB per Unit × Units Sold
This helps calculate actual investment cost of sold portion.
5. Capital Gain or Loss
Formula:
Capital Gain/Loss = Proceeds − Cost of Sold Units
- Positive value = Profit
- Negative value = Loss
Example of Adjusted Cost Base Calculation
Let’s understand with a real-world example.
Investment Details:
| Parameter | Value |
|---|---|
| Purchase Price | $100 |
| Units Purchased | 10 |
| Fees | $20 |
| Sell Price | $130 |
| Units Sold | 5 |
Step 1: Total Cost
(100 × 10) + 20 = $1020
Step 2: ACB per Unit
1020 ÷ 10 = $102 per unit
Step 3: Sale Proceeds
130 × 5 = $650
Step 4: Cost of Sold Units
102 × 5 = $510
Step 5: Capital Gain
650 − 510 = $140 Profit
Final Result:
| Metric | Value |
|---|---|
| Total Cost (ACB) | $1020 |
| ACB per Unit | $102 |
| Sale Proceeds | $650 |
| Capital Gain | $140 |
ACB Calculation Table for Quick Reference
| Purchase Price | Units | Fees | Total Cost | ACB per Unit |
|---|---|---|---|---|
| $50 | 10 | $10 | $510 | $51 |
| $100 | 5 | $15 | $515 | $103 |
| $200 | 2 | $20 | $420 | $210 |
| $75 | 8 | $8 | $608 | $76 |
What Is Capital Gain?
Capital gain is the profit earned when you sell an asset at a higher price than its adjusted cost base.
Types of Capital Gain:
- Short-term gain: Held for a short period
- Long-term gain: Held for longer duration
Capital gains are important for tax reporting and investment evaluation.
What Is Capital Loss?
A capital loss occurs when you sell an asset below its adjusted cost base.
Example:
- ACB per unit = $100
- Sell price = $80
- Loss per unit = $20
Capital losses can sometimes be used to offset taxable gains depending on tax laws.
