From The Money Manual team, here are 6 ways to make extra money online:

1. This Company Pays Up To $20 Per Survey

2. This Website Pays Out Over $1.6 Million In Cash Rewards Monthly

Brands want to know what you think and are willing to pay big time for it. Why? Your feedback helps them improve their products, which will ultimately make them more money. So, your opinions are pretty valuable and Survey Junkie will make sure you’re rewarded for every single one.

In a single day, Survey Junkie pays out $55,000 in cash and gift card rewards to its members. Completing four or more a day could earn you as much as $130 a month. And if you want to maximize your earning potential, keep an eye out for its monthly promotions, product testing, and focus groups, which can have even bigger payouts. To date, Survey Junkie has paid out $76 million.

Like Branded Surveys, Survey Junkie pays in points. As soon as you’ve earned 500 points ($5), you can start redeeming them for cash with PayPal or by bank transfer, plus gift cards from Visa, Amazon, Target Walmart and more.

If you’re active, you could bring in a few hundred dollars a month with this company’s surveys alone. You can sign up in less than 30 seconds and take your first survey today.

4. Get Up To $500 Whenever You Need It -- No Credit Check Or Delays

Earnings: Up to $500

In need of some extra cash to get you through a tough spot? We've all been there, and sometimes all you need is just a few extra hundred dollars to hold you over until your next paycheck.

When the going gets tough and money is tight, the app Dave is always there to help. Dave offers quick relief with cash advances up to $500 without all the complexities of a traditional bank loan. There are no credit checks, interest charges, or late fees, and it offers fast deposits -- I'm talking in as little as a few minutes.

Getting an ExtraCash advance from Dave is simple:

Link your bank account, answer a few questions, and Dave will confirm your eligibility and borrowing limit.

Choose the desired amount within your limit and submit your request.

Get your advance instantly with a Dave Spending Account, pay a small fee for an external debit card transfer, or receive it free within one to three days to an external bank account.

Dave provides a settlement date, typically your next payday or the nearest Friday after taking the advance, to repay the borrowed amount.

Once the borrowed amount is repaid, the cool-off period ends, allowing you to borrow again.

If you don't end up spending all of the money you borrowed, you can transfer it over to your ExtraCash™ account, reducing the amount you'll have to pay back next time.

If you're looking for a more steady way to boost your income, check out Dave's side hustle listings. You can explore and apply for local and flexible jobs, including paid survey opportunities, from its network of partners. Since launching this feature in 2019, Dave has connected thousands of members with profitable gigs that have earned them millions.
