The Moment
You just received a $10,000 bonus.
This is real money. Enough to eliminate a credit card balance, fully fund an emergency account, or make a meaningful investment that compounds for decades. The worst thing you can do is let it sit in checking while you decide. Every week of indecision is a week of lost opportunity.
The Decision Logic
At $10,000, the priority stack works sequentially — fund each level before moving to the next.
Step 1 — Eliminate high-interest debt If you carry any debt above 8% APR, direct the bonus there first. $10,000 against a 22% APR credit card saves you $2,200 in interest in the first year alone. No investment delivers a guaranteed 22% return.
Step 2 — Complete your emergency fund If you have less than 3 months of expenses in liquid savings, fill the gap. At $4,000/month in expenses, a 3-month target is $12,000. If you have $5,000 saved, put $7,000 from the bonus here and allocate the remaining $3,000 to the next step.
Step 3 — Capture your employer match If your employer offers a 401(k) match and you are not maximizing it, increase your contribution rate. You cannot deposit a bonus directly into a 401(k), but you can increase your contribution percentage for the rest of the year and use the bonus to replace the paycheck reduction.
Step 4 — Invest the rest Remaining funds go into a Roth IRA (up to $7,000/year) or a taxable brokerage account in low-cost index funds.

Tax Considerations
Your employer withholds taxes on bonuses at a flat 22% federal supplemental rate. On a $10,000 gross bonus, expect roughly $7,800 after federal withholding (state taxes vary). Plan your allocation based on the net amount, not the gross.
If the bonus pushes your annual income near a tax bracket boundary, a traditional 401(k) contribution can reduce your taxable income and may save you more than investing in a taxable account.

Frequently Asked Questions
Should I pay off my mortgage with a $10,000 bonus?
Usually no. Mortgage rates are typically 3-7%, and the interest is often tax-deductible. The expected return from investing in equities (historically ~10%/year) exceeds most mortgage rates. Prioritize higher-rate debt first.
Should I invest all at once or spread it out?
Lump-sum investing outperforms dollar-cost averaging about two-thirds of the time. For $10,000, investing it all immediately in a diversified index fund is the statistically optimal choice. If the volatility makes you uncomfortable, invest in two or three tranches over 2-3 months.
