Save vs invest: which is better?
The short answer
Save what you'll need inside 3 years — emergency fund, near-term goals — in a high-yield savings account. Invest what you won't need for 5+ years in low-cost, diversified index funds. Anything between is judgment.
Signals to weigh
- 01Time horizon — under 3 years is savings territory, over 5 is investing territory.
- 02Emergency fund status — 3-6 months of expenses is table stakes.
- 03Job stability — less stable means more cash on hand.
- 04Debt profile — high-interest debt beats both.
How to decide
- Step 1Fund the emergency account first, in a high-yield savings account.
- Step 2Automate investing contributions on payday, not what's left at month-end.
- Step 3Diversify across broad-market index funds — skip stock picking early.
- Step 4Reassess allocation once a year, not once a week.
