The general rule of thumb for investing priorities is:

1. Invest in your company 401(k) plan up to the match
2. Pay off short-term, non-tax-deductible debt (e.g., credit card, car loan)
3. Establish an emergency fund; 6-12 months of living expenses is a good guidepost
4. Put the maximum allowable amount in a Roth IRA (if eligible)
5. Put the maximum allowable amount in your company 401(k)
6. Invest the remainder in taxable accounts
7. Pay down tax-deductible debt (e.g., home mortgage)
