Most Tier-1 brokers now support recurring buys for popular ETFs and mutual funds. The setup takes minutes; the discipline lasts decades if you do not overcomplicate it.
Setup sequence
- Confirm the account type (taxable vs tax-advantaged) matches the goal.
- Link a bank account and test a small transfer.
- Pick 1–3 core holdings—not twelve overlapping ETFs.
- Schedule the buy date after salary clearance.
- Enable contribution step-ups annually if your platform allows.
Operational gotchas
- Settlement timing can delay first purchases.
- Fractional shares help small SIPs—confirm your broker supports them.
- Dividend reinvestment is separate from contribution automation; enable both intentionally.
Conclusion
Auto-invest is infrastructure. Build it once, review yearly, and resist the urge to redesign the machine every time markets move.
