1. What is Dividend Reinvestment Cost Basis?

Dividend reinvestment cost basis refers to the adjusted cost basis of an investment when dividends are automatically reinvested to purchase additional shares. This affects your capital gains calculation when you eventually sell the investment.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Old\ Basis \) — Original cost basis of your investment
• \( Dividend\ Reinvested \) — Amount of dividends reinvested to purchase additional shares

Explanation: Each time dividends are reinvested, they increase your total cost basis in the investment, which reduces your taxable capital gain when you sell.

3. Importance of Cost Basis Calculation

Details: Accurate cost basis tracking is essential for tax purposes. When you sell shares, the difference between sale price and cost basis determines your capital gain or loss.

4. Using the Calculator

Tips: Enter your original cost basis and the amount of dividends that were reinvested. Both values must be in USD and non-negative.

5. Frequently Asked Questions (FAQ)

Q1: Why is cost basis important for dividend reinvestment?

Q2: How often should I update my cost basis?
A: Update with each dividend reinvestment to maintain accurate records for tax reporting.

Q3: Does this calculator account for multiple reinvestments?
A: This calculates a single adjustment. For multiple periods, you would need to run the calculation sequentially.

Q4: What if I only reinvest some dividends?
A: Only include the amount actually reinvested, not the total dividend payment.

Q5: How does this affect my taxes?
A: While reinvested dividends are taxable in the year received, they also increase your cost basis, reducing future capital gains.
