Overdraft fees can be a major drain on your finances. Some banks charge more than $30 per overdraft and potentially charge that fee multiple times per day if you keep making transactions that overdraw your checking account. If you want to avoid these fees, you can typically opt out of overdraft coverage with your bank. It can be useful, however, to set up overdraft protection instead of opting out so you don’t find yourself unable to pay for something urgent.

Overdraft protection is a checking account feature that some banks offer as a way to avoid overdraft fees. There are several types of overdraft protection, including overdraft protection transfers, overdraft lines of credit and grace periods to bring your account out of a negative balance. Some other overdraft coverage programs might be a combination of these features.

Before you opt out of overdraft protection altogether — which means your bank will decline any transaction that would result in an overdraft — consider how you might need overdraft coverage in an emergency. For example, maybe you’re using your debit card to pay for gas on a road trip. You need enough fuel to get home but don’t have enough money in your checking account. Instead of dealing with running out of gas, you may want to deal with an overdraft.

Here are more details about the main types of overdraft protection that banks tend to provide.

Overdraft protection transfers. When a bank allows you to make an overdraft protection transfer, you can link a savings account, money market account or a second checking account at the same bank to your main checking account. If you overdraft your checking, your bank will take the overdrawn funds from your linked account to cover the cost of the transaction. Many banks allow this service for free, but some banks charge a fee.

Overdraft lines of credit. An overdraft line of credit functions like a credit card — but without the card. If you don’t have enough money in your account to cover a transaction, your bank will tap your overdraft line of credit to cover the remainder of the transaction. Lines of credit often come with steep annual interest rates that are broken up into smaller interest charges that you keep paying until the overdraft is paid back. Be aware that a line of credit could end up being expensive if you use this option to cover your overdrafts.

Grace periods. Some banks offer grace periods, so instead of immediately charging an overdraft fee, the bank will give you some time — typically a day or two — to return to a positive account balance after overdrafting. If you don’t do so within that time frame, your bank will charge you fees on any transactions that overdrafted your account.

Other coverage programs. Some banks are taking a new approach to overdraft protection by offering what’s basically a free line of credit with a longer grace period for customers to bring their account to a positive balance. One example, Chime’s SpotMe® program, allows customers to overdraft up to $200 with no fees. The customer’s next deposit is applied to their negative balance, and once the negative balance is repaid, customers can give Chime an optional tip to help keep the service “free.”

Chime says: “Chime is a financial technology company, not a bank. Banking services provided by, and debit card issued by, The Bancorp Bank or Stride Bank, N.A.; Members FDIC. Eligibility requirements and overdraft limits apply. SpotMe won’t cover non-debit card purchases, including ATM withdrawals, ACH transfers, Pay Friends transfers or Chime Checkbook transactions.”

Startup business grants can help small businesses grow without debt. But if you want free money to start a company, your time may be better spent elsewhere. Competition for small-business grants is fierce, and many awards require time in business — often at least six months.

Some grants are open to newer businesses or true startups. And even if you don’t qualify now, it can pay to know where to look for future funding. Here are the best grants for small-business startups, plus alternative sources of startup funding to consider.

Some government programs offer direct funding to startups looking for business grants, but those that don’t may point you in the right direction or help with applications:

Grants.gov. Government agencies routinely post new grant opportunities on this centralized database. If you see an opportunity relevant to your business idea, you can check if startups are eligible. Many of these grants deal with scientific or pharmaceutical research, though, so they may not be relevant to Main Street businesses.

Local governments. Lots of federal grants award funding to other governments, like states or cities, or to nonprofit economic development organizations. Those entities then offer grants to local businesses. Plugging into your local startup ecosystem can help you stay on top of these opportunities.

Small Business Development Centers. These resource centers funded by the Small Business Administration offer business coaching, education, technical support and networking opportunities. They may also be able to help you apply for small-business grants, develop a business plan and level up your business in other ways.

Minority Business Development Agency Centers. The MBDA, which is part of the U.S. Department of Commerce, operates small-business support centers similar to SBDCs. The MBDA doesn’t give grants to businesses directly, but these centers can connect you with grant organizations, help you prepare applications and secure other types of business financing.

Some local business incubators or accelerators offer business grants or pitch competitions with cash prizes. To find these institutions near you, do an online search for “Your City business incubator.”

Even if you don’t see a grant program, sign up for their email newsletter or follow them on social media. Like SBDCs and MBDAs, business incubators often provide business coaching, courses and lectures that can help you develop your business idea.

Lots of corporations and large nonprofits, like the U.S. Chamber of Commerce, organize grant competitions. Some national opportunities include:

iFundWomen. iFundWomen partners with other corporations to administer business grants. You can fill out a universal application to receive automatic notifications when you’re eligible to apply for a grant.

Amber Grant for Women. WomensNet gives two $10,000 Amber Grants each month and two $25,000 grants annually. Filling out one application makes you eligible for all Amber Grants. To qualify, businesses must be at lesat 50% women-owned and based in the U.S. or Canada.

National Association for the Self-Employed. Join NASE, and you can apply for quarterly Growth Grant opportunities. There are no time-in-business requirements for these grants of up to $4,000, but you’ll need to provide details about how you plan to use the grant and how it will help your business grow.

FedEx Small Business Grant Contest. This annual competition awards grants to small-business owners in a variety of industries. You can sign up to receive an email when each application period opens. To be eligible, you’ll need to have been selling your product or service for at least six months. Be mindful, though, that each grant cycle receives thousands of applications.

Fast Break for Small Business. This grant program is funded by LegalZoom, the NBA, WNBA and NBA G League and administered by Accion Opportunity Fund. You can win a $10,000 business grant plus free LegalZoom services. Applications open during the NBA season, which runs from fall to early summer each year.

New businesses likely won’t be able to rely on startup business grants for working capital. The following financing sources may help accelerate your growth or get your startup off the ground:

SBA microloans offer up to $50,000 to help your business launch or expand. The average microloan is around $13,000, according to the SBA.

The SBA issues microloans through intermediary lenders, usually nonprofit financial institutions and economic development organizations, all of which have different requirements. You can use the SBA’s website to find a lender in your state.

Asking friends and family to invest in your business may seem daunting, but it’s very common. Make sure you define whether each person’s money is a loan and, if so, when and how you’ll pay it back. Put an agreement in writing if possible.

Business credit cards can help you manage startup expenses while your cash flow is still unsteady. You can qualify for a business credit card with your personal credit score and some general information about your business, like your business name and industry.

You’ll probably need to sign a personal guarantee, though, which is a promise that you’ll pay back the debt if your business can’t.

If your business has a dedicated customer base, they can help fund you via crowdfunding. Usually businesses offer something in exchange, like debt notes, equity shares or access to an exclusive event.

There are lots of different crowdfunding platforms that offer different terms, so look around to find the model that works best for you.
