Understanding your real investment cost is essential for making smart financial decisions. Whether you are trading stocks, ETFs, cryptocurrencies, or other investment assets, knowing your Adjusted Cost Base (ACB) helps you accurately calculate your true cost per unit and determine your capital gains or losses.
Adjusted Cost Base Calculator
Our Adjusted Cost Base Calculator is a powerful financial tool designed to help investors, traders, and portfolio managers quickly compute ACB, per-unit cost, total proceeds, and profit or loss in just a few seconds.
Instead of manually performing complex calculations, this tool simplifies everything by using a structured formula-based approach that ensures accuracy and saves time.
What Is Adjusted Cost Base (ACB)?
The Adjusted Cost Base (ACB) represents the total cost of acquiring an investment, including:
- Purchase price of assets
- Number of units purchased
- Brokerage fees or transaction costs
It is used to determine the true cost per unit of an investment after including all associated expenses.
ACB is widely used in:
- Stock trading
- Mutual funds
- ETF investing
- Cryptocurrency investments
- Real estate shares
- Long-term portfolio tracking
Without calculating ACB, investors may miscalculate profits or pay incorrect taxes on capital gains.
Why Is ACB Important for Investors?
The Adjusted Cost Base is essential because it:
- Helps determine real investment profitability
- Ensures accurate capital gains reporting
- Includes transaction costs in investment valuation
- Prevents overestimating profits
- Supports tax calculations in many countries
- Helps improve long-term portfolio management
For tax reporting purposes, especially in countries like Canada and the U.S., ACB is a critical financial metric.

Adjusted Cost Base Formula Explained
The calculator uses standard financial formulas to determine accurate investment values.
1. Total Cost Formula
Total Cost = (Purchase Price × Units) + Fees
This includes both investment cost and additional expenses.
2. ACB Per Unit Formula
ACB per Unit = Total Cost ÷ Total Units Purchased
This gives the true cost of each unit after expenses.
3. Total Sale Proceeds Formula
Proceeds = Sell Price × Units Sold
This calculates total revenue from selling assets.
4. Cost of Sold Units Formula
Cost of Sold = ACB per Unit × Units Sold
This shows how much the sold portion originally cost.
5. Capital Gain / Loss Formula
Capital Gain or Loss = Proceeds − Cost of Sold Units
- Positive result = Profit
- Negative result = Loss
Example Calculation of Adjusted Cost Base
Let’s understand with a real-world example:
Investment Details:
| Parameter | Value |
|---|---|
| Purchase Price | $20 |
| Units Purchased | 100 |
| Brokerage Fees | $50 |
| Sell Price | $30 |
| Units Sold | 40 |
Step 1: Total Cost
(20 × 100) + 50
= 2000 + 50
= $2050
Step 2: ACB Per Unit
2050 ÷ 100 = $20.50
Step 3: Total Sale Proceeds
30 × 40 = $1200
Step 4: Cost of Sold Units
20.50 × 40 = $820
Step 5: Capital Gain
1200 − 820 = $380 Profit
Final Result:
| Calculation | Value |
|---|---|
| Total Cost | $2050 |
| ACB per Unit | $20.50 |
| Sale Proceeds | $1200 |
| Capital Gain | $380 |
