What Is the Biweekly Money-Saving Challenge?

The biweekly money-saving challenge involves putting away cash for 26 weeks, or every other week, for one year. The amount you decide to save can vary based on your goals and comfort level. This method not only helps you accumulate savings, but it also encourages you to develop consistent savings habits over time.

Key Points

•   Many different savings challenges are available to suit your lifestyle and budget, encouraging positive money-saving habits.

•   Depending on your budget, you could save between $1,000 and $10,000 with the 26-week/biweekly savings challenge.

•   Strategies like the 100-envelope challenge and the holiday helper fund can simplify saving for special events and take the stress out of annual holidays.

•   Savings challenges can last as long as you need them to and can be tailored to your goals, such as paying off debt or funding a trip.

•   Budgeting is key, and surplus funds from simple lifestyle changes can be put into savings each month.

Types of Biweekly Money-Saving Challenges

If you’re paid twice a month, the biweekly money-saving challenge might be more suitable for your lifestyle. It’s also budget-friendly, so you can adjust this plan according to how much you have left after covering your necessary expenses.

26-Week or Biweekly Savings Challenge

There are many versions of this challenge. You can start with a small savings amount, like $3, in the first week. Every two weeks, add an extra $3 to the last amount you put away. In the second week, that would be $6, and then $9 in the third week. At the end of the 26-week challenge, if you started with $3, you’ll have $1,053 in savings.

Alternatively, you might prefer a fixed savings goal, such as $5,000 or $10,000. If so, put away $193 to $385 every two weeks. After a year, you’ll have between $5,018 and $10,010.

How to Choose a Money-Saving Challenge

Choose a financial problem that you want to address. Setting targets and starting small can lead to big wins in many ways. Learning to put money aside lays the building blocks for long-term savings habits that can last a lifetime.

Find a challenge that’s budget-friendly. The amount you put away can be as little as a nickel on day one. The more you have to spare, the more you can save. Some challenges suggest using savings accounts or stashing cash. If you choose to open multiple accounts, keep in mind that traditional Federal Deposit Insurance Corporation accounts earn some interest and allow you to access funds for emergencies or planned expenses.

You might have specific financial goals, such as putting money aside for an emergency or funding a wedding. Or, you might want to build a habit of saving. Whatever your goal, a challenge can help you commit to saving $500 to $15,000 in a set period while building good habits.

Common Money-Saving Challenges

Money-saving challenges are smart saving strategies or smart spending strategies, depending on what you choose. They can show you how to save money quickly or in the long term.

And there’s no shortage of creativity. Google, TikTok, and Instagram list hundreds of money-saving challenges. You can even try saving $2,026 in the 2026 money-saving challenge. Below is a list of money challenges to get you started.

100 Envelope Challenge

In the 100 envelope challenge, you number 100 envelopes from 1 to100. Each day, choose one and put in the amount of cash written on the envelope. By the end of 100 days, you’ll have $5,050 stashed away.

Alternatively, you can break down the 100 days into 13 weeks (the final week is four days). For more manageable deposits, set aside a week’s total savings every other week. The table below details the amounts:

Week Amount
1 $28
2 $92
3 $156
4 $220
5 $284
6 $348
7 $412
8 $476
9 $540
10 $604
11 $668
12 $732
13 $490

Holiday Helper Fund

The holidays sneak up on us quicker than we expect. If you’re planning your annual budget, set up an account or an envelope for extra funds. If you need to pay for gifts in the year ahead, be it for a holiday, a wedding, or a birthday, this keeps the money out of sight and mind until you need it.

Starting in the week of January 1, set aside $20 every week, or $40 every two weeks. By December 25, you’ll have $1,040.

52-Week Savings Challenge

In the 52-week savings challenge, you set aside $1 in week one, then continue to deposit an amount equal to the week number. By the end of the 52 weeks, you’ll have saved $1,378. You can also start with $2 or $10 in week one, $4 or $20 in week two, $6 or $30 in week three, and so on. You’ll save $2,756 with the $2 challenge or $13,780 with the $10 challenge.

Another variation keeps the weekly savings contribution at a fixed amount, which can be particularly helpful for smaller budgets. For example, you can put away $10 a week to save $520 by the end of the challenge.

No-Spend Challenge

Brunching on Sunday? Maybe not if you’re taking on the no-spend challenge.

Pick a week or weekend and only spend money on necessities during that time frame. It’ll give you a chance to be creative with your limited financial resources.

Instead of eating out, try a new recipe at home. Dig deep into your closet instead of buying a new pair of shoes. You set the time limit, so you can continue to save until you notice a change in your accounts!

Cash-Only-for-a-Month Challenge

A 2024 Forbes Advisor survey found that people tend to spend more with bank cards than with cash. A cash diet can help stave off overspending. Leave your cards at home when you go out and only take a cash amount that you’re willing to spend.

Spending stimulates the part of your brain associated with reward, pleasure, and addiction. Take this opportunity to look at the categories in your budget where you tend to overspend, such as entertainment or clothes, and set aside cash for those categories. You can only spend the cash allotted for those categories.

365-Day Nickel-Saving Challenge

If you have a nickel to spare, this challenge is feasible. On day one, put a nickel in a jar. On day two, put 10 cents in the jar. On the third day, add 15 cents. By day 365, you’ll be adding $18.25 to make a total of $3,339.75 in your savings. You won’t have to put away more than $20 in a day and $130 in a week for the entire challenge.

30-Day Budget Preparedness Challenge

It helps to have a map to find where you’re going. The same is true with spending.

Challenge yourself to a budget. First, download a budget planning spreadsheet template or a budget planner app. Then, go through the categories (housing, groceries, entertainment, etc.) and add the amount you must or would like to spend in each.

Knowing how much to spend before you go out can help improve your planning and control your spending. For example, if you allocate $400 a month to groceries, you can make sure you spend $100 or less a week. If you don’t spend what you allocated, you can put the surplus in your savings.

Money-Saving Challenge Potential Savings

Taking on one of these challenges can help you boost your savings by $1,000 to $10,000.

Goal-setting will help you determine how much you want to save. If your target is $20,000 in two years, try the biweekly savings challenge. If you want to have $1,000 in your account, take on the 52-week savings challenge for a fun, concrete way to start.

If spending less is your goal, a challenge can help you cut overspending habits. Setting up a budget and spending cash (rather than using cards) can help. Some challenges also help you monitor your finances if paying off debt is your goal.

Whatever your goal is, these challenges are practical journeys that can pay off.

The Takeaway

A money-saving challenge can be a fun way to build a savings account. It can motivate you to spend less and save more. It can also be a concrete demonstration of how small savings can add up.

One of the more popular options is the biweekly money-saving challenge. You can put away an amount you can afford, such as $4, and increase it by $4 each week. Or, you can set a goal of $5,000 and aim to set aside about $193 each week. It’s an easy plan that you can adapt to your situation.

After completing one of these challenges, you’ll find you have stronger budgeting skills, including saving money and prioritizing debt payoffs. These skills could help you make more fiscally responsible decisions. That way, when life happens, you’ll be better prepared.
