The DRIP Reinvestment Calculator helps you forecast the future value of an investment, taking into account the power of compounding and the automatic reinvestment of dividends (DRIP). Provide four of the five variables, and we will solve for the missing one.

DRIP Reinvestment Calculator Formula
The calculation for the Future Value (FV) with regular contributions and compounding is derived from combining the Future Value of a Lump Sum and the Future Value of an Annuity Due (since contributions are made at the beginning of the period). We solve for the missing variable using this relationship.
FV = P(1 + R)^T + C * [((1 + R)^T - 1) / R] * (1 + R)
Variables Explanation
Understand the key variables used in this DRIP Reinvestment calculation:
- Initial Investment (P): The principal amount you start with.
- Annual Contribution (C): The fixed amount of money reinvested or contributed annually. This can represent the annual dividend payout being reinvested.
- Annual Rate of Return (R): The estimated annual growth rate, expressed as a decimal (e.g., 8% = 0.08).
- Time Period (T): The total number of years the investment is held.
- Future Value (FV): The estimated total value of the investment after the specified time period.

What is DRIP Reinvestment?
A Dividend Reinvestment Plan (DRIP) is an arrangement offered by a corporation that allows investors to automatically reinvest their cash dividends into additional shares or fractional shares of the company stock. This mechanism bypasses broker commissions and is a highly efficient way to harness the power of compounding for long-term wealth accumulation.
DRIP reinvestment is a powerful strategy because it continuously increases your share count. Since dividends are paid on the total number of shares you own, each reinvested dividend increases the base for the next dividend payout, creating a compounding loop that accelerates portfolio growth.
How to Calculate DRIP Reinvestment (Example)
Let’s calculate the Future Value (FV) if you start with $5,000, contribute $500 annually, expect an 8% return, over 10 years:
- Define Variables: P = $5,000, C = $500, R = 0.08, T = 10.
- Calculate Principal Growth: Calculate the future value of the initial lump sum: $5,000 \times (1 + 0.08)^{10} = \$10,794.62$.
- Calculate Contribution Growth: Calculate the future value of the annuity (contributions + reinvested dividends): $\$500 \times [\frac{(1 + 0.08)^{10} – 1}{0.08}] \times (1 + 0.08) = \$7,789.70$.
- Sum Totals: Add the two components to find the total Future Value: $\$10,794.62 + \$7,789.70 = \$18,584.32$.
- Conclusion: The estimated Future Value after 10 years is $18,584.32.
Frequently Asked Questions (FAQ)
This calculator assumes annual compounding and annual contributions (reinvestments) for simplicity. Most real-world DRIPs reinvest quarterly, which would yield a slightly higher result due to more frequent compounding.
Is the Annual Rate of Return (R) the same as the dividend yield?No. The rate R should be your *total* expected annual return, including both the dividend yield and the expected capital appreciation (share price growth). For example, if the stock grows 5% and yields 3%, R = 8%.
What if I only want to calculate the initial investment’s growth without contributions?Simply leave the “Annual Contribution/Reinvestment” field blank or enter 0. The calculator will then solve for the Future Value of the principal alone.
Why does the calculator require me to enter four variables?This calculator is a solver. The underlying financial formula has five interdependent variables. To solve for one (the unknown), you must provide the values for the other four.
