That’s where our Long Term Gains Calculator comes in. This easy-to-use tool helps you estimate the future value of your investment, calculate your total gains, determine how much tax you’ll owe, and see your net profit after taxes.
Long Term Gains Calculator
What is a Long Term Gains Calculator?
A Long Term Gains Calculator is a financial tool that projects the growth of your investment over time, considering compound interest and capital gains tax.
When you invest money, the return grows annually at a specific rate (your annual growth rate). After several years, your money compounds, meaning your investment earns returns on both the initial investment and the accumulated gains.
However, when you sell your investment, you may owe capital gains tax, which reduces your net profit. The calculator helps you plan better by factoring in taxes and showing your actual take-home returns.

Here are some benefits of using this calculator:
- Future Planning – Estimate how much your investment will grow over 5, 10, or even 30 years.

Example Calculation
Let’s assume:
- Initial Investment: $10,000
- Annual Growth Rate: 8%
- Holding Period: 10 years
- Capital Gains Tax Rate: 15%
Step 1: Calculate Final Value 10,000×(1+0.08)10=21,589.2510,000 \times (1 + 0.08)^{10} = 21,589.2510,000×(1+0.08)10=21,589.25
Step 2: Calculate Total Gain 21,589.25−10,000=11,589.2521,589.25 - 10,000 = 11,589.2521,589.25−10,000=11,589.25
Step 3: Tax Owed 11,589.25×0.15=1,738.3911,589.25 \times 0.15 = 1,738.3911,589.25×0.15=1,738.39
Step 4: Net Gain After Tax 11,589.25−1,738.39=9,850.8611,589.25 - 1,738.39 = 9,850.8611,589.25−1,738.39=9,850.86
Result:
- Final Value: $21,589.25
- Total Gain: $11,589.25
- Tax Owed: $1,738.39
- Net Gain After Tax: $9,850.86
This shows how much tax affects your true profit, even though your investment nearly doubled.
