Despite how carefully you plan, there will always be times when you can use some extra cash.

Over the years there have come several times when I came into a pinch for cash. I just needed that extra $200 for rent or I couldn't afford lunch for a few weeks so I went without. This especially comes true during the holiday season when money is pulled in many different directions.

Here are 50 ways that you can make an extra $100 today.

1. Claim money that you're owed.

NAUPA (National Association of Unclaimed Property) is a free government website that allows you to locate any unclaimed funds owed to you through the National Association of State Treasurers. All you have to do is visit their website, enter your name, and search any state or province where you live or have resided. You may discover that there is unclaimed payroll checks, over payments, and maybe unclaimed inheritances for you to claim.

2. Collect bank and credit card bonuses.

If you open a new bank account or credit card, you'll be rewarded with a bonus. For example, if you open-up a new Chase Total Checking account and set up direct deposit you'll get $200. Sticking with Chase, if you get the Chase Freedom Unlimited card, you'll earn a $150 sign-up bonus.

3. Gather-up spare change.

If you're like most people, you probably have coins laying around your car and hidden under your couch. You probably even have some bills stashed in a jacket that you forgot about it. I used to keep a coin jar and would cash it in when I was pinched a little, back-in-the-day. I would always be shocked when the amount totaled $200 to $300.

4. Work overtime or on holidays.

If you're employed, ask or volunteer for overtime. Of course, how much you earn depend on your position and industry that you work in. I have a friend who works security at a power plant and makes $120 per hour if he works overtime on a holiday like Christmas. He'd rather work Christmas than face the In-Laws, anyway.

There are also countless retail companies who hire just for seasonal work on odd hours. Great way to make extra holiday cash.

5. Substitute teach.

There's a shortage of subs in the U.S. In some districts, you can make more than a hundred bucks a day. However, it may be less depending on the district, and in some instances, your education. Visit the National Education Association to get more information on substitute teaching for each state. Get signed up for this early so they can check you out. You fill out am employment form. If they call you can always say, "no," but if you need quick cash -- call in early and they will find you a place that day.

6. Get rid of your old gadgets.

I don't think you'll get much for your old flip phone. But, if you have a newer gadget, like last year's smartphone or tablet, then you can sell them on eBay or Craigslist to make a few extra bucks. Again, try this out now and get signed up, so if you are ever in a pinch, you already know how to sell and get the cash fast.

7. Sell thrift-store clothing.

I've known plenty of people who visits a thrift store or local Goodwill. One of these people starts by looking online for in-demand items. This person then purchases these items for a couple of bucks at the local thrift and flips them online for a nice profit.

8. Clean-out your books and DVDs.

If you're like me, you have some books and DVDs just collecting dust in your home. You can sell them on sites like Amazon, Half.com, and SecondSpin. You don't need to worry that your Millennial friends or kids say, "What the he** is a DVD? These sell really well.

9. Flip freebies.

Just go on Craigslist and look for people giving away stuff for free. You may be able to flip those items for a couple of bucks, but that adds up quickly. If it's just junk, like a broken washer, you can go visit the scrap yard and sell the metal -- some want the old washer pieces.

Years ago when I lost my job I did this for nearly 6 months. It kept money flowing into my bank account. It's amazing what people will give away for free just to get rid of it. If you have a friend with a truck you have an extra bonus!

10. Sell other people's junk.

If you don't have much to sell, or just want to bulk-up your inventory, sell stuff that belongs to your friends, family, or neighbors, that they don't want. Sometimes they'll just give you their junk if they're cleaning out their home, but it's always fair to give them a cut. You won't believe what "junk" older people will let you dig through in the garage if you mow their lawn, dig leaves out of the rain gutter and take out the trash. They'll pay you for the work, too.

11. Rent out your stuff.

If you don't want to part with belongings, but still want to monetize them, then you can rent them out. Anything from yard tools to an extra bedroom on Airbnb, your car to your garage or parking space. My sister-in-law rents out her couch nearly every weekend for weddings, because it's so awesome.

12. Scrap metal.

If you have a pickup, or at least know someone who does, then you can collect scrap metal from friends, family, neighbors, and even people getting rid of it on Craigslist for next-to-nothing. You then go directly to your local scrap yard and make some quick cash. Here's a site that tells you the scrap metal prices and provides some professional advice as well.

13. Sell your photos.

Even if you're not a professional photographer, but enjoy capturing images, especially unusual images, then you can sell your photos to stock photography like Shutterstock, Fotolia, iStock Photo, and Foap. You don't make a fortune on these, but every time your photo is purchased you'll get paid.

Here is a photography guide to help you in your journey.

14. Sell unused gift cards.

Do you have a bunch of unused gift cards lying around? You can sell them on sites like Cardpool and get up to 92% cash back.

15. Visit the pawn or consignment shop.

If you have some clothing or furniture you want to unload, then consignment shops are a great option. You can also visit a local pawn shop and sell pretty much anything you want to them. You probably won't get the best price, but you'll get cash instantly. Also, pawn shops are an option for loans since they use your items as collateral. That means if you can't pay back the loan they'll keep the stuff that you brought-in. Baby items, prom dresses, wedding dresses and business attire for women sell really well and there are quite a few shops around.

16. Have a yard sale.

Sometimes you can just sell your unwanted items directly in your front yard. Of course, location and weather can impact your sale. I would suggest organizing a community yard sale so that it becomes an event that draws more potential customers. Get your signs up early and go back and take those signs down so everyone can continue to have yard sales.

17. Re-sell old gifts.

We've all received a gift that we either don't like or already have. If it's still in the package you can return it to the retailer. In most cases, retailers will accept them up to a year later.

18. Pamper pets.

If you're a pet owner then you definitely don't mind paying people to take care of your extended family. In fact, you can earn about $100 a night for pet-sitting. You can also charge people to walk or feed their pets while they're at work or on vacation.

19. Join a clinical trial.

Clinical trials can pay between $300-$500 per visit. You'll make more money though for overnight rials.

20. Donate bone marrow.

Bone marrow, which is also a tissue that's found in the centers of the large bones, contains stem cells. If you donate your bone marrow, you should be able to make a couple of hundred bucks. You make more money for a first time donation -- so make sure you get the extra money for that. Just search Google "donate bone marrow for money near me."

21. Create 20 posts on Fiverr.

If you're not familiar with Fiverr, it's a site where people are $5 per hour to do freelancing tasks ranging from creating product videos to logo design to writing articles. Even though you're making $5, if you have the skills, these tasks don't eat much of your time, so you can be able to crank out 20 posts in-a-day. There are even many gis that will pay much more than $5.

22. Test drive cars.

As a way to attract potential customers, car dealerships are offering cash or gift cards to test drive a new vehicle. For example, Kia has been offering a $25 Visa Prepaid card when you test-drive a new Kia. Some of these incentives can go-up to $100.

23. Drive with Uber.

Uber drivers make on average $19 per hours, so driving for half-a-day can earn you that extra $100. But, depending on where you live, that rate could be closer to $30 per hour. Just remember, Uber takes 20%, you have to be 21, have three of driving experience, don't have a criminal record, and have a newer vehicle with four-doors. Again, sign up now whether you need the cash or not -- so that when you need it -- you can just go.

24. Use TaskRabbit.

TaskRabbit is used by people to run errands, make it repairs, or deliver groceries to them. If someone needs a ride to the airport or doctor appointment right now, build a cabinet, or drop-off their groceries right now you can come-in and save the day. For a price, of course. Sign up takes a couple of days.

25. Do odd jobs.

We all have jobs that we dread doing, or just don't have the time to do. It could be anything from mowing, pulling weeds, raking leaves, cleaning gutters, detailing a car, of installing a new entertainment system. If you know anyone in this position -- offer to do these odd jobs for a quick $100.

26. Start "busking."

If you have a talent, such as playing a musical instrument or juggling, then you can earn cash by busking, aka street performing. If you don't have a skills, you can just dress-up in a costume and make some quick cash.

27. Sell stuff on the side of the ride.

Pick a busy street corner and start selling bottles of water on a hot day, roses near Valentine's Day, or bags of produce for hungry commuters. One day it was a downpour raining, my sister and her boyfriend when to the dollar store and bought 30 umbrella's. They then went to a movie theater and sold them for $10. (I would have asked $15, but you see what I mean.)

28. Presell your labor.

Sometimes there isn't a need to do chores like mowing, babysitting, or building a website immediately. However, you can still charge your friends and family in advance for a chore that you'll do when they need it. You better be dependable though. Again, older people will love, love, love you!

29. Sell your hair.

Although it would be preferable to donate your hair, if need cash quickly then you can sell your 12 inches of untreated hair on sites like BuyandSellHair.com and HairWork.com for hundreds of dollars. There are a couple of sites that now take treated hair that they sew on hats for costumes.

30. Make a bet.

I'm not advocating gambling. After all, that's pretty much throwing your money away. You can, though, make some friendly bets at the bar with your friends or colleagues. These simple tricks could quickly add-up. But, just don't go overboard. Some of your friends may get annoyed.

31. Trade stocks.

Most broker sites have deals when open a new account with $1,000 and make just one trade, you'll earn $100. Stock trading can be very risky so don't go crazy but if you have a good feeling on a stock, this could earn you good money.

32. Trade cryptocurrencies.

The days of becoming a millionaire by buying and selling bitcoins may be over, there are a number of alternative cryptocurrencies that are still emerging, which means that you can buy them low and sell them high in the short-term. I would recommend that you review this guide before jumping into this headfirst.

33. Sell your crafts.

If you're crafty and have a bunch of your handmade projects, such a s jewelry or furniture, laying around the house then start selling on sites like Etsy or at or your local flea market. Etsy also likes vintage clothing.

34. Cash-in on your hobbies.

If you're into golf, then caddy for the day. If you're an amazing guitar players, give lessons at your local music shop. If you love crunching numbers, then start tutoring students who are struggling at math. In other words, start cashing-in on your hobbies.

35. Start a lemonade stand.

Lemonade stands aren't just for kids. You can set-up your own earning stand on those steamy summer afternoons. During the winter you can sell hot cocoa to warm-up your customers. Pretend your kid just ran in the house to get more, and you are the good parent helping them out.

36. Sell event tickets.

If you have tickets for an in-demand concert or sporting and either can't go, or just don't feel like going, then you can sell the tickets on number of sites like Stubhub. Just make sure that you obey the law.

37. Have a bake sale.

Bake a delicious batch of cookies, brownies, or cupcakes and sell them at work. I bet you'll earn a pretty penny by the end of the workday. My mom bought bread from, "the bread kid," every week. His mom made it fresh, and her kids delivered the bread, breadsticks and cinnamon rolls. -- it was great. The key to this business would be to only have a couple of offerings (such as: only bake bread or breadsticks on Monday, Wednesday, and Saturday).

38. Cook for others.

If you have some cooking chops then you can start cooking for others. Whether that's selling lunches at work or getting a down payment for an upcoming catering event, this is an obvious side gig for chefs-at-heart. I have a friend who cooked dinner for over-worked families a few days a week. Pretty soon the business got so big, she moved to Vegas -- out in the suburbs -- and has become a millionaire many times over.

39. Join a mock jury.

Lawyers want to try their case out before taking it front of jury. And, they're willing to pay you for that. This site claims that you can make as much as $100 a day as a mock juror.

40. Test websites.

There's a company called User Testing where you can make up to $30 per hour for browsing around websites and answering a couple of questions. Typically it only takes about 15 minutes to complete the process.

41. Work today for pay today.

There are plenty part-time gigs that will pay you at the end of the day. Check out these jobs on sites like Indeed, Snagajob, PeopleReady, and Craigslist.

42. Cut your expenses.

If you've created a budget then you already have spotted the areas where you're spending excessively. Make a couple of small cuts, such as changing your phone and cable plan, cutting your insurance premium, and consolidating your debt, can add-up to a hundred bucks easily. The very biggest cut I've found is to stop eating out.

This by far is one of the quickest ways to have more money in your account.

43. Get paid for your ideas.

Most organizations have a suggestion box, but did you know that some will actually pay you for your awesome idea? If you're employer doesn't do this, then you can turn to places like ThinkGeek.com or Innocentive.com who will reward you for your creativity.

44. Blog.

There are thousands of companies looking for good content online. Try approaching a local company and seeing if they are looking for paid writers. Chances are, you'll get a couple clients that will pay you money each month. General rule of thumb is charge on a per word basis. When beginning, try and get $50 per post. I know countless sites that will pay upwards of $500 per post.

Here is a guide I put together to put together amazing content as well as get paid online.

45. Refer new customers.

Some employees also reward their team members when pointing new customers in their direction. If so, then put on your salesman's hat and start attracting potential customers.

46. Get your deposit back.

If you opened up a utilities account, and didn't have the best of credit at the time, then you probably had to put down a deposit. If you made consecutive payments for the last year then you should qualify to get that deposit back. This practice does vary from state-to-state.

47. Collect debts.

There's a good chance that someone out there owes you some cash. Don't procrastinate on these late payments. Debts that go more than 45 days late have only an 18% chance of getting paid. Pick-up the phone and start collecting, even if it's just a portion of they owe you.

48. Cash in part of your IRA.

If you have an IRA at a local bank then you can walk-in and take money out of your account. This is usually a last resort since you'll have to pay the taxes due, as well as a penalty when you file your tax return. It ends up being about half of the money -- but you have to do what you have to do.

49. Get a payday advance.

This isn't the norm, but there are cases where a boss will give you an advance on your paycheck. For example, you could ask for $500 in advance and pay back $100 on your next five paychecks. Some bosses will just give you the loan out of their own money.

50. Ask for a raise.

If you've earned it, then ask your boss for a raise. Even just a couple of bucks per hour can add-up to $100 during a full day's work.
