Saving vs. investing: when should you do each?
Saving vs. investing is an asset-building decision. The choice depends mainly on when you expect to need the money and whether you could leave it invested after a market decline.
Money for emergencies, essential expenses and near-term goals should usually remain liquid. Money that will not be needed for many years may be suitable for investing if you can accept the risk of loss.
Many people need both. Savings provide access and stability. Investing gives long-term money more opportunity to grow while exposing it to market risk.
What is the difference between saving and investing?
Saving keeps money accessible and generally exposes it to less risk than investing. Investing puts money into assets whose value can rise or fall, with the aim of earning a higher return over time.
Deposits at FDIC-insured banks and NCUA-insured credit unions receive federal insurance within applicable limits. Securities, mutual funds and similar investments are not federally insured. You can lose the principal, which is the amount you invested.
Savings accounts typically pay lower interest than the return investors seek from investments. If the interest rate does not keep pace with inflation, the money loses purchasing power. Investments provide more growth potential while carrying more risk.
Which money should stay in savings?
Money should usually stay in savings when you may need it unexpectedly or on a known date in the near future. Access and stability matter more than potential growth in these situations.
This includes money for emergencies, upcoming bills and planned purchases. Selling an investment during a market decline could leave you with less money than the expense requires.
The right emergency reserve depends on your circumstances. Past unexpected expenses, changes in income, essential spending and other available resources can help you decide how much to keep. A fixed rule will not suit every household.
How does your time horizon affect the decision?
Your time horizon is the number of months, years or decades before you expect to use the money. A shorter time horizon usually supports less investment risk because there is less time to recover from a market decline.
A goal due within a few months or years may arrive during a weak market. Keeping that money liquid reduces the chance that you will need to sell an investment at a loss. The closer and less flexible the spending date, the stronger the case for savings.
A longer time horizon may allow you to accept more risk. It gives investments more time to recover from losses, although time does not remove the possibility of losing money.
How much investment risk can you afford to take?
Your capacity for investment risk depends on how much you rely on the money and whether you can withstand a loss. It can differ from the amount of risk you feel comfortable taking.
You may feel willing to accept risk while having limited capacity for loss. This can happen when the money is needed for routine expenses, emergencies or a planned purchase. If you must sell during a decline, you may realize a loss.
Money is more reasonably investable when it is left after routine, emergency and planned spending needs are covered, has a long time horizon and can remain invested during a large decline. All investments carry risk, including the possible loss of principal.
Can you save and invest at the same time?
You can save and invest at the same time by assigning money to separate goals. Each amount can then be treated according to when it will be needed and how much loss you can tolerate for that goal.
| Situation | Likely treatment | Main reason |
|---|---|---|
| Emergency or essential spending | Keep liquid | Reliable access |
| Near-term or fixed-date goal | Usually keep liquid | Limited recovery time |
| Long-term money beyond planned needs | Potentially invest | More time to tolerate market changes |
| Money serving several goals | Separate by purpose | Each goal has different requirements |
The split can change over time. Building an emergency reserve may take priority at first. As that reserve grows and near-term needs are covered, more new money may become available for long-term investing.
What should you do once money is ready to invest?
Once money is reasonably investable, the next decision is how to build an investment portfolio that matches your time horizon and capacity for loss.
Portfolio construction includes asset allocation, implementation and review. The separate guide to portfolio diversification explains which risks diversification can reduce and what it cannot prevent.
Cash held inside an existing investment portfolio serves a different purpose from emergency savings. Its role depends on the portfolio’s expected withdrawals and investment plan.
