How Much Money Should You Have in the Bank? A Realistic Guide

Ideally, what you should have in the bank would be a full month's expenses plus some extra cash in your checking account, and three to six months' worth of expenses in a savings account reserved for emergencies.

The exact amount you need might be higher or lower depending on your income, expenses and financial goals. This guide will help you zero in on a realistic goal matched to your unique needs.

Key Takeaways

• Aim for one month's expenses plus a buffer in checking and three to six months' expenses in savings when you're deciding how much money you should have in the bank.

• Build in a checking buffer: Add 20% to 30% on top of one month's expenses so an unexpected bill doesn't overdraw your account.

• Size your emergency fund to your risk: Three months' expenses works for stable, dual-income households — six months is safer for a sole earner or unpredictable income.

• Put idle cash to work: Money beyond your buffer and emergency fund can earn more in a high-yield savings account, money market account or CD instead of a low-yield checking or standard savings account.

• Match the account to the timeline: Keep near-term cash liquid and consider investing only money you won't need for five years or more.

How Much To Keep in Checking vs. Savings

You should have at least one month’s worth of living expenses in your checking account, plus a buffer to keep unexpected expenses from overdrawing your account. Your savings account should have three to six months' worth of expenses to tide you over in case you lose your job or suffer some other financial setback. 

Whereas these guidelines provide a general rule of thumb, the next section explains how to calculate the specific amount you need in your bank accounts.

How To Calculate Your Savings Needs

Calculate your checking and savings needs based on your actual spending.

For Your Checking Account

Your checking account should have one month's worth of expenses, plus a buffer of 20% to 30% of your monthly spending. 

• Add up your fixed monthly bills, such as rent/mortgage, insurance, subscriptions, memberships and minimum debt payments.

• Calculate your average monthly spending on variable expenses like groceries, utilities, personal care, healthcare, transportation, household items and entertainment. 

• Add the two totals.

• Multiply the new total by 1.20 or 1.30, depending on your preferred buffer size, to get your ideal checking account goal.

How To Calculate Your Ideal Checking Account Balance

To see how this works in action, imagine you have $2,500 in monthly expenses and want a 30% buffer. You'd use this formula: 2,500 x 1.30 = $3,250. This tells you that you should start the month with $3,250 in your checking account.

For Your Emergency Fund

The savings account calculation is easier because you've already done most of the math, but you'll have to decide on a savings goal before you start.

Three months' worth of living expenses is a good initial goal if your household has stable income and more than one earner. Six months' expenses is safer if you're your household's sole earner or your household income is unpredictable. 

Now, calculate your emergency savings goal. Using the previous example, it would look like this: 

• 2,500 x 3 = $7,500, or

• 2,500 x 6 = $15,000

Where Should You Keep Your Money? Choosing the Right Bank Account

Which account is right for your money depends on when you'll need to access the fund and how risk-tolerant you are.

Checking accounts are meant for transactions, so most pay little, if any, interest, but they make it very easy to access your cash. Standard savings accounts also have low yields — so low that your money basically sits idle until you need it. That's why it makes sense to keep extra money in high-yield savings, money market and/or CD accounts, where stronger returns keep your money working for you so you hit your goals faster.

Consider investing money you won't need for five years or more. Investments have better long-term growth potential, but volatility makes them risky in the shorter term. 

How Do You Know If You Have Too Much or Too Little in the Bank?

Holding too much money in the bank is a missed opportunity for stronger growth, but holding too little is risky.

You might be holding too much money if:

• You have more in your checking account than you need for next month's bills plus a buffer.

• You have money sitting in a standard savings account that could be earning higher interest in a high-yield savings account, money-market account or CD.

• You’re routinely hitting your checking account target and have surpassed your emergency-savings target but have no goal for the extra money.

• Your deposit account balances exceed $250,000.

You might be holding too little money if:

• You’re regularly using credit cards to pay day-to-day expenses because you're worried your checking balance will come up short.

• An unexpected $500 to $1,000 expense would create a financial hardship or force you to take on debt.

• You've overdrawn your checking account in the past year because you ran out of money before your bills were paid.

FAQ

Answers to the following banking questions might help you decide how much money in the bank is enough.

Is it bad to keep more than $250,000 in one bank?

It can be risky if your accounts are single (individual) accounts in the same category, such as deposit accounts — checking, savings, money-market accounts and CDs. FDIC insurance won’t cover the amount that exceeds $250,000 in that case. 

Should I keep my emergency fund in the same bank as my checking account?

Maybe, if both accounts suit your goals. Having both accounts in the same bank makes for quick transfers and might earn you relationship perks. But those perks won’t necessarily make up for a lower annual percentage yield than you might earn by keeping your savings elsewhere. Compare rates, fees and account features from a few banks before deciding where to keep your money.

How often should I recheck how much I’m keeping in each account?

The exact frequency depends on your overall financial situation. If your income is stable and your goals haven’t changed, you might pick a date for an annual review. But major life events such as marriage or the birth of a child, and changes in income or expenses warrant additional check-ins.

Does a joint account change how much FDIC insurance covers?

Yes, in that FDIC insures each joint account holder up to $250,000 across their joint accounts. So together, you’re covered for up to $500,000. That’s in addition to each account holder’s $250,000 in coverage across their single accounts.

Key Terms

• Emergency fund: Money set aside — typically three to six months' worth of living expenses — to cover unexpected costs or a loss of income.

• Checking buffer: Extra cash — often 20% to 30% of monthly spending — kept above your bills to avoid overdrafts.

• FDIC insurance: Federal coverage that protects deposits at insured banks up to $250,000 per depositor, per bank, per ownership category.

• NCUA share insurance: The credit union equivalent of FDIC coverage, insuring member deposits up to $250,000 per member, per credit union, per ownership category.

• High-yield savings account: A savings account paying an above-average interest rate while keeping your money liquid.

• Money market account: A deposit account that typically pays higher interest than standard savings and may offer limited check-writing or debit access.

• Certificate of deposit (CD): A time deposit that locks in a fixed rate for a set term, usually with a penalty for early withdrawal.

• Risk tolerance: Your comfort with the possibility of losing principal, which helps determine how much of your money belongs in savings versus investments.
