7 Smart Ways to Build Your Emergency Fund

Pay Yourself First

A hassle-free way to ensure that you contribute regularly to an emergency fund is to set up automatic deposits to your savings account, says Sean McQuay, a credit card expert for NerdWallet.com. That way, you'll neither forget to make a monthly contribution to your emergency fund nor allow excess spending to crowd out your planned savings at the end of the month.

You're likely already having your paychecks deposited directly into your checking account. Simply add a second direct deposit with your employer, steering a small portion of your pay to your savings account. Or set up an automatic transfer from your checking account to a savings account. You'll rest easy knowing that your emergency fund is growing steadily on its own.

Save Your Tax Refund

If you're expecting a refund check this tax season (the average refund is about $3,000), don't blow it on a shopping spree at the mall or on that 70-inch 4KTV you've been coveting. Give your emergency funds a jolt instead.

Adjust Your Tax Withholding

Now that you've put this spring's tax refund to good use in your emergency fund, let's take a different approach with your taxes going forward. Instead of waiting until next spring to receive another refund to add to your emergency fund, adjust your tax withholding now in order to receive more money in your paycheck each pay period. (Our Easy-to-Use Tax Withholding Calculator will show you exactly how much extra cash you could be taking home.)

To make the change, you'll need to submit a revised W-4 form to your employer. You should see the adjustment in your next paycheck. Remember, the extra cash you receive shouldn't be spent frivolously. If you have an automatic transfer to an existing emergency fund set up, increase the amount to account for the additional money you'll be receiving.

Find a Part-Time Job to Earn Extra Cash

If your schedule permits, pick up some part-time work to boost your savings. In addition, "expanding your income stream can help provide protection against the inevitable swings of economic cycles," says consumer savings expert Andrea Woroch.

Consider turning a passion -- say, copywriting or web design or music -- into a side job, using your skill set to help small businesses via freelancing sites such as Upwork.com or Fiverr.com. Or sign up for TaskRabbit.com, which lets you help individuals with their errands and odd jobs during your spare time for a small fee, Woroch adds.

Cut Back on Monthly Expenses

Don't have the time or inclination to put in extra hours to generate more income? Instead, scale back on everyday expenses to free up money in your budget to contribute regularly to your emergency fund.

To save on costly takeout meals throughout the week, prep your own meals on the weekends, and freeze them for quick access on weeknights, Woroch recommends. You can also reduce fixed expenses, such as car insurance (consider 14 Discounts You Can Get on Your Auto Insurance), home insurance (see One Simple Way to Cut Your Home Insurance Premiums), your mobile phone plan (see 8 Best Wireless Phone Plans for Every Type of User) or cable TV service (see Save Big by Getting Rid of Your Cable TV). It may be as simple as calling your service provider and requesting a discount, Woroch says.

If you save $100 a month with these moves, put $100 a month into your emergency fund.

Save Your Spare Change

Think about all the loose change you find in your car, your purse or around the house -- or the few dollars in change that your pocket accumulates throughout a busy day of errands. It adds up.

• Keep a jar or lockbox somewhere in your home where you can routinely toss spare change. Every three months, tally it up and deposit it into your emergency fund.

Don't use cash often? There are smartphone apps that can help you make the most of the "spare change" lingering in your checking account. Money Crashers' Schrage suggests digit, which, when linked to your checking account, analyzes your income and daily spending habits and then recommends a small amount to be transferred to your savings account. He also likes Acorns, an app that rounds up your everyday purchases (i.e., coffee, movie tickets or lunch) to the nearest dollar, then moves the difference into a diversified portfolio recommended for you. (Both apps are available on iTunes and Google Play; digit is free, but Acorns charges $1 per month plus an annual 0.25% commission on balances greater than $5,000.)

Some banks, including Bank of America and Wells Fargo, will even move the "spare change" from your debit-card purchases into your savings account.

Take the 52-Week Challenge

We've seen this tactic championed across the internet, and my husband and I are using it this year. Here's how it works: Starting the first week in January, set aside one dollar for your emergency fund. Easy, right? In week two, save two dollars. And so on. Every week, you need to stretch to save only one more dollar than the previous week. By the end of the year, you'll be setting aside $52 a week.

And by then, you will have saved nearly $1,400. "Such incremental savings help people stay on target and reach their goal because it's easier to make small changes than complete life overhauls," Woroch says.

Want to give it a try? Remember, if you're starting the challenge today, you'll need to play catch-up with your contributions to meet your $1,400 savings goal by the end of the year.
