How to Fully Automate Monthly Investing

6 min readCompound

Key takeaways

Automating monthly investing is the most effective way to eliminate the two most common investment sins: market timing and procrastination. The system works regardless of mood, news, or how busy you are.

Two Steps to Full Automation

The entire system rests on two elements: a standing order from your current account to your investment account and an automatic purchase plan set up directly with your broker. The first ensures a regular supply of capital; the second invests it immediately. Together they create a system that runs without a single manual step.

How to Set Up an Automatic Purchase Plan with Your Broker

Many modern brokers offer a scheduled purchase feature — you specify the ETF, amount, and frequency and the broker buys automatically. Verify the terms: whether automatic purchases are free or fee-based, what the minimum volume is, and whether the broker buys whole or fractional shares. Fractional shares allow you to invest an exact fixed amount with no remainder.

Golden rule of automation: set it and forget it. The only regular action is an annual review — not a monthly manual purchase.

What Automation Naturally Delivers

Automatic regular purchases are the precise implementation of a DCA strategy — you buy at both low and high prices, average your purchase price, and eliminate the need to decide on timing. This is the greatest psychological value of automation: you made the decision once, and the system then repeats it without emotion.

When to Reassess Automation

Automation requires no intervention, but check it once a year: Does the contribution amount match current income? Is the chosen ETF still the right instrument for your plan? Has your life situation changed enough to warrant adjusting the strategy? This annual check is everything a passive investor needs. How to track your portfolio even with automation and without stress is explained in the article on portfolio monitoring.
