How to Set Up Automatic Investing
Last updated: March 2026
Automate your ETF investing so wealth builds on autopilot. Step-by-step instructions for setting up recurring purchases at major brokerages with the right amount and frequency.
Step 1: Determine Your Monthly Investment Budget
Before setting up automation, calculate how much you can invest each month consistently. Review your monthly take-home pay and subtract essential expenses including rent or mortgage, utilities, groceries, insurance, and minimum debt payments. From the remaining amount, allocate a portion to investing. A common target is ten to twenty percent of your gross income, but even fifty dollars per month is a meaningful start. The critical requirement is sustainability. Choose an amount you can maintain for at least twelve months without needing to stop. It is far better to automate one hundred dollars per month consistently than to start at five hundred, stop after three months, and not resume for a year.
Step 2: Choose Your ETFs and Allocation
Decide which ETFs your automatic purchases will go into and what percentage of your monthly investment each fund receives. For most beginners, a simple approach works best. Option one is a single fund strategy: put one hundred percent into VTI or VOO for total simplicity. Option two is a two-fund strategy: split between a US stock ETF and an international stock ETF, such as seventy percent VTI and thirty percent VXUS. Option three is a three-fund strategy: add bonds with something like sixty percent VTI, twenty percent VXUS, and twenty percent BND. Write down your specific ETF tickers and their percentage allocations before proceeding to the setup step.
Step 3: Verify Your Broker Supports Automatic ETF Investing
Not all brokers offer the same automatic investing features. Fidelity offers automatic recurring investments in both ETFs and mutual funds with fractional share support and no additional fees. Schwab offers automatic investing for ETFs with Schwab Intelligent Portfolios or through their standard platform for Schwab-branded ETFs. Vanguard supports automatic investing for ETFs through their platform. Most other major brokers including Interactive Brokers and Merrill Edge have similar features. Log into your broker account and search for automatic investing, recurring investments, or scheduled purchases in their settings or help section. If your broker does not support automatic ETF purchases, consider switching to one that does because automation is that important.
Step 4: Link Your Bank Account and Set Up Transfers
Ensure your bank account is linked to your brokerage account for automatic funding. Set up a recurring automatic transfer from your bank to your brokerage on a date that aligns with your payroll schedule. If you are paid on the first and fifteenth, schedule your transfer for the second of each month. Allow one to two business days for the transfer to settle before your automatic investment executes. Some brokers combine the bank transfer and ETF purchase into a single automated workflow, while others require you to set them up separately. Test the process with a small manual transfer first to confirm the bank link works correctly before relying on it for recurring automation.
Step 5: Configure Your Recurring ETF Purchases
Navigate to your brokerage's automatic investment or recurring purchase section. For each ETF in your plan, create a recurring buy order specifying the dollar amount, the ETF ticker symbol, and the frequency such as monthly, biweekly, or weekly. Set the execution date a day or two after your bank transfer settles to ensure funds are available. If your broker supports fractional shares, enter the exact dollar amount for each ETF. If it only supports whole shares, you may need to adjust your amounts slightly. Review the summary of all your recurring orders to confirm the total matches your planned monthly investment. Submit the configuration and verify you receive a confirmation email or notification.
Step 6: Enable Dividend Reinvestment
While you are setting up automation, also enable automatic dividend reinvestment for every ETF you own. This is sometimes called DRIP, or dividend reinvestment plan. When your ETFs pay dividends, typically quarterly, those cash payments will automatically purchase additional fractional shares of the same ETF instead of sitting as uninvested cash. This ensures every dollar in your portfolio is always working for you and compounds continuously. Most brokers have a global dividend reinvestment setting you can enable for all holdings at once, or you can configure it per individual ETF. Check that it is turned on after your first purchase to confirm the setting applied correctly.
Step 7: Set Calendar Reminders for Annual Reviews
Automation should not mean you forget about your investments entirely. Set a calendar reminder for once per year to review your automatic investment setup. During this annual review, evaluate whether you can increase your contribution amount based on income changes. Check that your ETF allocation still matches your goals and risk tolerance. Verify all recurring purchases are still executing correctly by reviewing your transaction history. Confirm dividend reinvestment is active. Consider whether life changes like marriage, a new job, or a baby require adjustments to your plan. Outside of this annual review, resist the urge to tinker with your setup. The power of automation comes from consistency over time.
Pro Tips
- ✓Schedule your automatic investment for the day after payday so the money is invested before you can spend it on non-essentials.
- ✓Start with a smaller amount than you think you can afford and increase it gradually once you confirm it is sustainable.
- ✓Use a separate checking account solely for investment transfers to keep your investment funding visually separate from spending.
- ✓Set up email or push notifications for each automatic purchase so you have a passive awareness that the system is working.
- ✓If your broker does not support automatic ETF purchases, set up an automatic transfer to your brokerage and a recurring phone reminder to manually buy.
Common Mistakes to Avoid
- ✗Setting the investment amount too aggressively and having to pause or cancel automatic investments within a few months.
- ✗Not verifying that the bank-to-brokerage transfer arrives before the ETF purchase date, causing failed orders.
- ✗Forgetting to enable dividend reinvestment, leaving cash sitting uninvested in the account for months.
- ✗Pausing automatic investments during a market downturn instead of continuing to buy at lower prices.
