The Automation Hierarchy
- 401(k) payroll deduction: Most automated option — set % in payroll portal, money never enters your checking account
- Roth IRA auto-invest: Set monthly ACH transfer from checking to Roth IRA, set auto-invest feature on arrival
- HSA payroll deduction: Available if HSA is employer-sponsored; otherwise manual monthly transfer
- Auto-rebalance: Enable annual auto-rebalance in target-date funds or set calendar reminder
- Auto-increase: Enable 1% annual contribution increase in 401(k) settings

💡The Auto-Increase Trick
Log in to your 401(k) provider portal and enable automatic contribution escalation (1% per year is standard). This single setting, enabled once, systematically increases your investment rate with each passing year without requiring any decision or willpower. Most providers offer this feature; most employees have never enabled it.
