What to check first (before you act)

Goal and timeline

Before opening or choosing a checking account, clarify why you need it and when you’ll need access to the funds. Are you looking for an account for daily spending, to manage a specific project’s budget, or as a central hub for your finances? Your timeline—whether it’s short-term or ongoing—will influence the type of account and features that best suit you. For instance, if you anticipate needing funds for a large purchase soon, you’ll want an account with readily accessible cash.

Current cash flow

Understand how much money typically comes in and goes out of your accounts each month. This involves tracking your income sources (paychecks, freelance payments) and your regular expenses (rent, utilities, groceries, loan payments). Knowing your cash flow helps you choose an account that can handle your transaction volume without incurring excessive fees, such as overdraft charges if you consistently spend more than you have available.

Emergency fund or safety buffer

Do you have a readily accessible savings account or other liquid assets set aside for unexpected expenses? An emergency fund, typically covering 3-6 months of living expenses, acts as a crucial safety net. This buffer prevents you from dipping into your checking account for emergencies, which could lead to overdrafts or force you to miss bill payments.

Debt and interest rates

Assess any outstanding debts you have, such as credit card balances, personal loans, or student loans. Note the interest rates associated with each. High-interest debt can significantly hinder your financial progress. Understanding your debt situation helps you prioritize payments and avoid accumulating more debt by overspending from your checking account.

Credit impact

Your checking account activity, especially if it leads to overdrafts or missed payments reported to credit bureaus, can indirectly affect your credit score. While checking account activity itself isn’t directly reported like loan payments, consistent overdrafts can lead to accounts being sent to collections, which will impact your credit. Maintaining a positive banking relationship and managing your funds responsibly is part of overall financial health.

Step-by-step (simple workflow)

Step 1: Define Your Banking Needs

What to do: List your primary reasons for needing a checking account. Consider how you’ll deposit money (direct deposit, mobile deposit, ATM) and how you’ll make payments (debit card, checks, online bill pay, Zelle/P2P apps).
What “good” looks like: You have a clear understanding of your typical monthly transactions and preferred payment methods.
A common mistake and how to avoid it: Assuming all accounts offer the same features. Avoid this by researching different account types and their specific capabilities before choosing.

Step 2: Research Account Types

What to do: Explore the common types of checking accounts available, such as basic checking, interest-bearing checking, and rewards checking.
What “good” looks like: You can identify at least two account types that seem to align with your needs.
A common mistake and how to avoid it: Only looking at traditional brick-and-mortar banks. Avoid this by also considering online banks, which often offer lower fees and higher interest rates.

Step 3: Compare Banks and Credit Unions

What to do: Identify banks and credit unions that offer the account types you’re interested in. Look at their fee schedules, minimum balance requirements, and ATM networks.
What “good” looks like: You have a shortlist of 3-5 institutions to investigate further.
A common mistake and how to avoid it: Focusing solely on interest rates. Avoid this by prioritizing low fees and convenient access, as these often have a more significant daily impact on your finances.

Step 4: Review Fee Structures

What to do: Carefully examine the fee schedule for each potential account. Pay close attention to monthly maintenance fees, overdraft fees, ATM fees (especially for out-of-network machines), wire transfer fees, and inactivity fees.
What “good” looks like: You understand what triggers each fee and can identify ways to avoid them, such as maintaining a minimum balance or using direct deposit.
A common mistake and how to avoid it: Overlooking overdraft protection fees. Avoid this by understanding how overdraft protection works and its associated costs; sometimes, it’s cheaper to have transactions declined.

Step 5: Check Minimum Balance Requirements

What to do: Determine if the account requires you to maintain a minimum daily or average monthly balance to avoid fees.
What “good” looks like: You can comfortably meet the minimum balance requirement with your typical cash flow.
A common mistake and how to avoid it: Not checking the type of minimum balance required. Some require an average monthly balance, while others require a minimum daily balance. Understand which applies to avoid unexpected fees.

Step 6: Evaluate ATM Access and Networks

What to do: Consider how often you use ATMs and whether the bank has a convenient network of fee-free ATMs near your home, work, or frequent travel locations.
What “good” looks like: You have easy access to fee-free ATMs that meet your needs.
A common mistake and how to avoid it: Not factoring in out-of-network ATM fees. Avoid this by checking the bank’s ATM network map and considering the potential cost if you frequently use other banks’ machines.

Step 7: Assess Online and Mobile Banking Features

What to do: Investigate the quality and features of the bank’s online portal and mobile app. Look for mobile check deposit, bill pay, account alerts, and budgeting tools.
What “good” looks like: The online and mobile platforms are user-friendly and offer the features you need for easy account management.
A common mistake and how to avoid it: Assuming all mobile apps are created equal. Avoid this by reading reviews or trying out a demo if available to ensure the app is intuitive and functional.

Step 8: Understand Deposit Holds

What to do: Learn about the bank’s policy on holding funds from deposited checks. This determines when the money becomes available for you to use.
What “good” looks like: You understand the typical hold times for different types of deposits (e.g., local vs. out-of-state checks) and can plan your spending accordingly.
A common mistake and how to avoid it: Assuming all deposited funds are immediately available. Avoid this by asking about deposit hold policies, especially for large checks, to prevent unexpected shortages.

Step 9: Open the Account

What to do: Gather the necessary identification (e.g., driver’s license, Social Security card) and initial deposit. Visit the bank or complete the online application.
What “good” looks like: Your account is successfully opened, and you have received your account number and routing number.
A common mistake and how to avoid it: Providing incomplete or inaccurate information. Avoid this by double-checking all details before submitting your application to prevent delays.

Step 10: Set Up Direct Deposit and Bill Pay

What to do: Provide your employer or income sources with your new account and routing numbers for direct deposit. Set up any recurring bill payments through your bank’s online bill pay service or directly with the billers.
What “good” looks like: Your income is automatically deposited, and your essential bills are scheduled for payment, reducing the risk of missed payments.
A common mistake and how to avoid it: Forgetting to update automatic payments. Avoid this by creating a checklist of all recurring payments (subscriptions, loan payments) and updating them with your new account information.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Not checking for monthly maintenance fees	Accumulation of small fees that reduce your balance over time.	Choose an account with no monthly fee or one that offers a waiver (e.g., via direct deposit or minimum balance).
Ignoring overdraft fees	High fees for each transaction that exceeds your balance, quickly depleting funds.	Opt out of overdraft protection or link your checking to a savings account to cover shortfalls. Monitor your balance closely.
Using out-of-network ATMs frequently	Fees from both your bank and the ATM owner, significantly increasing costs.	Use your bank’s ATM network or choose an account that reimburses out-of-network ATM fees. Plan ATM visits to consolidate them.
Not understanding deposit holds	Unexpectedly low available balance after a deposit, leading to bounced checks.	Ask about your bank’s hold policy for different deposit types. Wait for confirmation that funds are fully available before making large withdrawals or payments.
Failing to monitor account balance	Accidental overdrafts, bounced checks, and missed payments.	Use mobile banking alerts, check your balance daily, or set up automatic notifications for low balances.
Not linking to a savings account	Overdrafts and missed payments when unexpected expenses arise.	Link your checking to a savings account for automatic overdraft protection. This is often cheaper than standard overdraft fees.
Not setting up alerts	Missing important account activity, like large withdrawals or low balances.	Activate email or text alerts for low balances, large transactions, and payment due dates.
Overlooking inactivity fees	Your account balance decreases if you don’t use it for a prolonged period.	Make at least one transaction (deposit or withdrawal) within the bank’s specified timeframe (e.g., every 6-12 months) to keep the account active.
Not understanding P2P transfer limits	Inability to send or receive funds quickly when needed, or unexpected fees.	Familiarize yourself with the daily and monthly limits for services like Zelle or Venmo, and the associated fees for exceeding them or for instant transfers.
Relying solely on paper checks	Slower payment processing and potential for lost or stolen checks.	Utilize online bill pay and debit cards for faster, more secure transactions. Keep a limited supply of checks for specific needs.

Decision rules (simple if/then)

• If you receive direct deposit regularly, then look for accounts that waive monthly fees with direct deposit because this is a common and easy waiver requirement.
• If you frequently use ATMs from other banks, then choose an account that reimburses out-of-network ATM fees because this can save you significant money.
• If you tend to have a low balance or have overdrafted in the past, then link your checking account to a savings account for overdraft protection because this is typically less expensive than standard overdraft fees.
• If you want to earn a little extra on your balance, then consider an interest-bearing checking account if you can meet the minimum balance requirements and avoid fees, because the interest earned might offset some minor costs.
• If you are comfortable managing your finances entirely online and rarely visit a branch, then explore online banks because they often offer lower fees and higher interest rates.
• If you need to deposit cash frequently, then check the number and location of fee-free ATMs or branches that accept cash deposits because this can be a limitation with some online-only banks.
• If you are concerned about overdrafts, then set up text or email alerts for low balances because this proactive notification can help you avoid accidental overdrafts.
• If you write a lot of checks, then ensure the account offers a reasonable number of free checks or that the cost of ordering checks is low because this can be a hidden expense.
• If you make international payments, then compare wire transfer fees across different institutions because these fees can vary significantly.
• If you are a student or a senior citizen, then look for accounts specifically designed for these demographics as they often have waived fees or special benefits because banks frequently offer tailored products.
• If you plan to use your checking account for budgeting tools, then check if the bank’s mobile app or online platform offers integrated budgeting features because this can simplify financial tracking.

FAQ

What is a checking account used for?

A checking account is designed for everyday transactions. It’s where you typically receive your income and from which you pay bills, make purchases with a debit card, write checks, and withdraw cash.

How do I avoid monthly maintenance fees?

Many banks waive monthly fees if you meet certain criteria, such as maintaining a minimum daily balance, having direct deposit set up, or linking your account to another account like a savings account. Check your bank’s specific requirements.

What happens if I overdraft my checking account?

If you spend more money than you have, you may incur an overdraft fee for each transaction that exceeds your balance. Some banks offer overdraft protection, which links to a savings account or a line of credit to cover the shortfall, often for a fee.

Can I earn interest on my checking account?

Yes, some checking accounts are interest-bearing. However, the interest rates are often lower than those offered by savings accounts, and these accounts may have higher minimum balance requirements or other fees.

How do I deposit money into my checking account?

You can deposit money through various methods: direct deposit from your employer, mobile check deposit via your bank’s app, depositing cash or checks at an ATM, or visiting a bank branch.

What is a debit card and how does it work with a checking account?

A debit card is linked directly to your checking account. When you use it for purchases, the money is immediately deducted from your account balance. It can also be used at ATMs to withdraw cash or check your balance.

How long do banks typically hold deposited checks?

Deposit hold times vary by bank and the type of check (e.g., local vs. out-of-state, personal vs. cashier’s check). Funds may not be immediately available, and it’s best to check your bank’s policy.

What is an account and routing number?

Your account number identifies your specific account at a bank, while the routing number identifies the bank itself. You need both for direct deposits, electronic payments, and wire transfers.
