How to use the DRIP simulator
- Enter your initial amount and monthly contribution. If you are not contributing, set the monthly amount to 0 and just enter the starting amount.
- Choose the expected annual dividend yield and the payout frequency (yearly, quarterly or monthly). Each payout equals the yield multiplied by the period divided by 12.
- Enter how much you assume the price grows each year (default 0%), your dividend tax rate and the number of years.
- Read the 10-year and 20-year results in the table, then use the charts to see how quickly reinvesting pulls ahead of taking the dividends as cash.
Why reinvesting creates compounding
If you take dividends as cash and spend them, the size of your holding stays the same and so does the dividend it produces. If you use the dividends to buy more of the same asset, you own more units, and those extra units produce the next dividend. Repeated for years, this looks just like interest earning interest. The longer the period, the higher the yield and the larger the monthly contribution, the bigger the gap becomes.
The simulator adds your monthly contribution, applies your assumed price growth, and on each payout month calculates value times the annual yield times the period divided by 12. After tax, that amount is reinvested in the DRIP scenario and set aside in the cash scenario. Both scenarios use the same contributions and price growth, so the difference between them comes only from reinvesting dividends.
What to keep in mind when reading the results
The row "Extra from reinvesting" is the difference between reinvesting and keeping the dividends as cash under identical conditions. The gap can look small in the first few years, but over 10 or 20 years it grows noticeably. The average monthly after-tax dividend is the dividend actually paid in the final year divided by 12, and the reinvested portfolio pays more because it holds more units.
These figures only hold if your assumptions hold. Real yields move with prices and company earnings, and some companies cut or skip dividends. When prices rise, the same dividend buys fewer units, and when prices fall it buys more. That is why it helps to try price growth of 0%, 3% and a negative value to see the range of outcomes.
Tax matters as well. Dividend taxation depends on your country, the type of account and your income, and tax-advantaged retirement or savings accounts can work very differently. This calculator applies a single rate, so enter the rate that fits your own situation.
Tips for using the simulator wisely
- A higher yield always makes results look better. Start from a conservative or historical average value and compare several scenarios.
- The monthly contribution often matters more than the yield. Keeping up a steady contribution is usually a surer lever than adding one point of yield.
- A high-dividend stock is not automatically a good investment. Check price volatility, the company finances and its dividend history separately.
- Trading fees, currency conversion costs and foreign withholding tax are not included, so real costs for overseas assets can be higher.
- Use the result to understand the concept rather than as a target, and talk to a financial professional before important decisions.
FAQ
What is DRIP?
DRIP stands for Dividend Reinvestment Plan. Instead of spending the dividends you receive, you use them to buy more of the same asset, so the new shares also pay dividends and the effect compounds. This tool turns that idea into numbers.
Will a 4% yield really grow my money 4% a year?
No. The simulator assumes the yield you enter is paid steadily every year. In reality the yield on price falls when prices rise, and companies can cut or stop dividends. Try the annual price growth field with different values to test other scenarios.
How is tax handled?
Each time a dividend is paid, the tax rate you enter is deducted and the remainder is reinvested or paid out. Your real rate depends on your country, account type and income, so enter the rate that applies to you.
How are reinvesting and taking cash compared?
Both cases use the same contributions and the same price growth. In the cash case the dividends you received are kept and added to the portfolio value for comparison, so the gap is purely the compounding from reinvesting.
How close is this to real results?
Fees, exchange rates, payout timing and amounts, price swings and tax changes all matter in real life. This calculator simplifies everything to monthly steps, so treat the result as a way to understand the concept, not as a target or promise.
