The Moment
You received a bonus — and for once, there is no fire to put out. No credit card balance demanding attention. No emergency fund gap keeping you up at night. Your financial foundation is solid.
This is the best kind of financial decision: choosing between good options. The question is not whether to invest — it is where and in what order.
The Investment Priority Stack
Step 1 — Capture your 401(k) match If your employer matches contributions and you are not yet maxing the match, increase your contribution rate. You cannot deposit a bonus directly into a 401(k), but you can raise your paycheck contribution and use the bonus to replace the reduced take-home pay. A 50-100% employer match is an instant, risk-free return.
Step 2 — Fund a Roth IRA If you are eligible (income under $161,000 single / $240,000 married), contribute up to $7,000/year. Roth money grows tax-free and comes out tax-free in retirement. If you are over the income limit, use the backdoor Roth conversion.
Step 3 — Taxable brokerage account Remaining funds go into a taxable brokerage in low-cost, tax-efficient index funds. Total market index funds (VTI, VTSAX) or target-date funds are solid choices. Avoid actively managed funds with high turnover — they generate unnecessary taxable events.

What Not to Do
Do not time the market. Invest the bonus now. Waiting for a dip costs more than it saves — markets go up more often than they go down, and time in the market beats timing the market.
Do not pick individual stocks. Unless stock picking is your hobby and you are using money you can afford to lose, index funds outperform the vast majority of stock pickers over 10+ year periods.
Do not overcomplicate. A three-fund portfolio (US stocks, international stocks, bonds) in the right proportions for your age is sufficient for most people. Sophistication does not equal returns.

Frequently Asked Questions
Should I invest the bonus all at once or dollar-cost average?
Lump-sum investing wins about two-thirds of the time because markets trend upward. For a bonus, invest it immediately. DCA is a behavioral tool — use it only if investing all at once would cause you anxiety that leads to panic-selling later.
Roth IRA or traditional 401(k) — which first?
Capture your 401(k) match first (it is free money regardless of account type). After that, if you are in the 22-24% bracket and expect higher future income, prioritize Roth. If you are in the 32%+ bracket, traditional 401(k) contributions save more on taxes now.
