Start with your emergency fund, then build from there
The amount you put in a savings account depends on two separate goals: covering unexpected costs without going into debt, and saving toward something specific. Most people should aim for an emergency fund of three to six months of living expenses in a savings account that you can reach quickly. After that, how much more you save depends on what you're saving for and when you'll need the money.
A savings account is not the best place for money you won't touch for years—that's what investment accounts are for. But for money you might need within the next few years, or money you want to keep safe and accessible, a savings account is the right tool. The question is how much makes sense for your situation.
Key Takeaways
- An emergency fund of three to six months of expenses should sit in a savings account you can access within one or two business days.
- Calculate your monthly expenses by adding up rent, food, utilities, insurance, and other regular costs, then multiply by three to six.
- After your emergency fund is in place, save additional amounts based on specific goals—a car down payment, a home repair fund, or a vacation.
- Keep money you'll need within two to three years in a savings account; money you won't touch for longer belongs in a different account type.
- The interest rate your bank pays matters more once you have several thousand dollars saved, so compare rates across banks before depositing large amounts.
Calculate your three-to-six-month emergency fund
Start by adding up what you spend each month. Include rent or mortgage, utilities, groceries, insurance, phone, internet, transportation, and any regular payments like loan installments or subscriptions. Don't include money you spend on wants—just the costs you have to cover to keep living where you are and staying healthy.
Once you have a monthly total, multiply it by three for a minimum emergency fund, or by six if you have irregular income, work in a field where jobs are less stable, or have dependents. If your monthly expenses are $3,000, a three-month fund is $9,000 and a six-month fund is $18,000. This is the amount that should be sitting in a savings account at all times, separate from money you use for regular bills.
If you're starting from zero, you don't need to reach this number before opening a savings account. Start with whatever you can—even $500 or $1,000—and add to it over time. The account exists to catch you if something breaks or you lose income, so having some money there is better than waiting until you have the full amount.
Add savings for specific goals and their timelines
Once your emergency fund is in place, decide what else you want to save for and when you'll need that money. If you're saving for a car down payment in two years, a home repair fund for the next five years, or a vacation next summer, each of these goes into your savings calculation separately.
For money you'll need within one to three years, a savings account is the right place because you can access it without penalty and the money won't lose value. For money you won't touch for five years or longer, you might explore other account types that pay more interest but have restrictions on when you can withdraw. Talk to your bank about what they offer.
Write down each goal, the amount you need, and when you need it. Then divide the amount by the number of months until that date to figure out how much to save each month. If you need $5,000 for a car down payment in 24 months, you'd save about $208 per month.
Account for the interest rate your bank pays
Banks pay different interest rates on savings accounts, and the difference matters more as your balance grows. A savings account paying 0.01% interest on $1,000 earns about 10 cents per year. The same account paying 4.5% earns about $45 per year. Once you have $10,000 or more saved, comparing rates across banks before you deposit becomes worth your time.
High-yield savings accounts at online banks often pay more interest than savings accounts at traditional brick-and-mortar banks. The tradeoff is that you can't walk into a branch, but you can still move money in and out online within one or two business days. If you're keeping $15,000 in an emergency fund, the difference between 0.01% and 4.5% is about $675 per year.
Interest rates change, so check what your bank is currently paying before you move a large amount. You can compare rates on the banks' websites or on financial comparison sites. Once you've chosen a bank, you don't need to move your money every time rates shift slightly—but if your bank's rate falls far behind others, moving to a higher-paying account makes sense.
Keep separate accounts for different purposes
You don't have to put all your savings in one account. Many people keep one savings account for their emergency fund and a separate one for a specific goal like a vacation or a down payment. This separation makes it easier to see how close you are to each goal and less tempting to dip into your emergency fund for something that isn't an emergency.
Some banks let you create multiple savings accounts within the same account holder profile, and some charge a fee for extra accounts. Check your bank's rules before opening a second account. If your bank charges fees for multiple accounts, you might use one account and track your different goals with a spreadsheet or notes app instead.
The key is that your emergency fund should be in an account you don't touch for non-emergencies. If you keep it mixed with money you're saving for a vacation, you might accidentally spend it and then have no cushion when something unexpected happens.
Adjust your savings amount as your life changes
The amount you need in savings changes when your income changes, when you move to a place with higher or lower costs, or when your family size changes. If you get a raise, you might increase your emergency fund. If you move to a more expensive city, your three-to-six-month calculation goes up. If you pay off a car loan, your monthly expenses go down and your emergency fund target might decrease.
Review your emergency fund target once a year or whenever something major changes in your life. You don't need to recalculate every month, but checking in annually keeps your number realistic. If you've been saving for a specific goal and you've reached it, decide whether to move that money into your emergency fund, start saving for a new goal, or spend it.
Frequently Asked Questions
What counts as an emergency?
An emergency is something unexpected that costs money and that you have to handle right away: a car repair, a medical bill, a broken appliance, or a job loss. It's not a vacation, a new phone, or a purchase you've been planning. If you can wait a month or save up for it gradually, it's not an emergency.
Should I keep my emergency fund in the same bank as my checking account?
You can, but many people keep it at a different bank to make it slightly harder to transfer money on impulse. If your emergency fund is at the same bank as your checking account, you might be tempted to move money over for non-emergencies. A different bank adds a one-to-two-day delay that gives you time to think. Either way works as long as you can access the money within a few business days if you truly need it.
Is $500 enough to start a savings account?
Yes. You don't need a minimum amount to open most savings accounts. Start with whatever you can save, even if it's $100 or $500, and add to it over time. Having some money set aside is better than waiting until you can save the full three-to-six-month amount.
What if I can't save three to six months of expenses?
Start with one month and work toward more. Even one month of expenses in savings is a cushion that keeps you from going into debt if something unexpected happens. Once you reach one month, aim for two, then three. You don't have to reach six months to have a working emergency fund.
Should I move my savings to a different account type once I reach my goal?
That depends on when you'll need the money and what other account types your bank offers. Money you might need within two to three years should stay in a savings account. Money you won't touch for five years or longer might earn more in a different account, but ask your bank what the tradeoffs are before you move it.
