Automating Contributions

Layer 1: Automating 401(k) contributions

This is the easiest automation to set up because it happens through payroll.

How it works:

1. Log into your employer's 401(k) system (Fidelity, Vanguard, Empower, etc.)
2. Choose your contribution percentage or dollar amount
3. Select which funds to invest in (or use a target date fund)
4. Save your settings

From that point forward:

• Money comes out of every paycheck before you see it
• It automatically buys your chosen funds
• You never have to log in unless you want to make changes

What percentage to choose:

• Minimum: enough to get the full match (usually 3-6%)
• Ideal: 10-15% if you can afford it
• Aggressive: 15-20%+ if you're pushing for early retirement

You can always adjust, but starting with "at least the match" is non-negotiable—that's free money.

Layer 2: Automating IRA transfers (bank → brokerage)

For Roth IRAs and Traditional IRAs, the money flow is different. You need to move cash from your bank to your brokerage first, then invest it.

Setting up automatic transfers:

1. Log into your brokerage (Fidelity, Schwab, Vanguard, etc.)
2. Link your bank account if you haven't already
3. Set up a recurring transfer (ACH pull)
• Example: $500 on the 5th of every month from checking to Roth IRA
4. Most brokerages let you set this up once and it repeats automatically

How to decide the amount:

• 2026 IRA contribution limit: $7,500/year ($625/month)
• If you can't do the full $625, start with $200, $300, $400—whatever fits
• You can always increase it later as income grows or debt drops

Timing tip:

• Schedule it a few days after your paycheck hits
• This ensures the money is there and doesn't bounce

Layer 3: Automating the actual investing (cash → funds)

Just because money is in your brokerage account doesn't mean it's invested. Cash sitting there earns almost nothing and doesn't grow.

You need to set it to automatically buy your funds.

How to set up automatic investing:

Option 1: Automatic Investment Plans (most brokerages)

• Log into your brokerage
• Go to "Automatic Investments" or "Recurring Investments"
• Choose the fund (e.g., FSKAX, VTI, target date fund)
• Set the dollar amount and frequency (e.g., $500 monthly)
• Link it to your automatic transfer date

Example flow:

• 5th of the month: $500 transfers from bank to brokerage
• 6th of the month: $500 automatically buys FSKAX

Option 2: Manual with reminders (backup plan)

• If your brokerage doesn't have great auto-invest features
• Set a calendar reminder to log in and buy once a month
• Not ideal, but better than nothing

For multiple funds:

• Some brokerages let you split: 60% to Fund A, 30% to Fund B, 10% to Fund C
• Or you can set up separate automatic investments for each fund

Automating taxable brokerage accounts

The process is identical to IRAs:

1. Set up recurring transfer from bank to taxable brokerage
2. Set up automatic investment into your chosen funds

The only difference is there's no contribution limit, so you can invest as much as you want.

When to prioritize taxable accounts:

• After maxing 401(k) match and Roth IRA
• If you're saving for goals before age 59½ (early retirement, house, etc.)
• If you want maximum flexibility

The complete automation blueprint

Here's what a fully automated investing system looks like:

Every paycheck (automatic):

• 10-15% goes to 401(k) before you see it
• 401(k) automatically buys your chosen funds

Every month (automatic):

• 5th: $500 transfers from checking to Roth IRA
• 6th: $500 automatically invests in FSKAX (or your chosen fund)
• 15th: $300 transfers from checking to taxable brokerage
• 16th: $300 automatically invests in VTI (or your chosen fund)

Your job:

• Check once every 3-6 months that everything is running smoothly
• Rebalance once a year if needed
• Increase contributions when income goes up

That's it. The system runs itself.

How to handle raises and bonuses

When your income increases, you have a choice:

• Let lifestyle inflation eat it all
• Redirect some or all of it to investing

My approach:

• Get a raise → immediately increase 401(k) contribution by 1-2%
• Or increase automatic IRA transfers by $50-100/month
• This "pay raise to future me" strategy compounds fast

For bonuses:

• Take 50-75% and make a one-time investment
• Use the rest for fun or current goals
• This way you get the dopamine hit now and the long-term benefit later

Common automation mistakes to avoid

Mistake 1: Automating transfers but not investing

• Money piles up in cash at the brokerage
• You're not actually invested
• Fix: Set up automatic fund purchases

Mistake 2: Setting it and literally never checking

• Automation doesn't mean total neglect
• Check quarterly or semi-annually that it's running
• Make sure nothing broke or changed

Mistake 3: Overcommitting and then quitting

• You automate $1,000/month but can't sustain it
• You turn it off and never turn it back on
• Better to start with $300 and increase gradually

Mistake 4: Not coordinating with paydays

• Transfers hit before your paycheck arrives
• Overdrafts or bounced transfers
• Fix: Schedule everything 2-3 days after payday
