Finance Expert Reveals 6 Viral Savings Boosters for 2026

Seven in ten 18- to 34-year-olds are prioritizing bulking up their savings this year, polls reveal, the same demographic driving TikTok’s explosion of viral saving hacks.

But which trends are gaining the most traction, and are they as solid as the online community makes them out to be? Experts at GIGACalculator identified the most popular savings trends.

Personal finance expert Lisa Stanley, co-founder of the green money site Good With Money and creator of the sustainable money app Zero, breaks them down.

1. 100-Envelope Challenge cash stuffing: Potential savings

The challenge with the highest saving potential is the 100-envelope challenge, with over 280k searches for its method in the past week alone. The idea is to label envelopes 1-100, then select a random envelope at a given frequency (e.g., twice a week). This method can also be done virtually, with a range of “envelope-free” budgeting apps releasing their own spin. Digital cash stuffing has seen over 148k searches on TikTok in the past week.

Lisa Stanley comments, “This is a good challenge to get you thinking about your budget and what’s available to spend or save, plus it has a seriously substantial saving potential. However, it’s time-consuming, and I would suggest time could perhaps be better spent looking up the best savings rates available to get the best rate of return on the money you have already set aside.”

Pros: Highest saving potential; random allocation means not having to incrementally save more
Cons: Cash option may be time-consuming, going to the ATM and physically stuffing the envelopes

2. 52-Week Challenge:

The 52-week challenge, designed to run through the whole year, is a classic and widely used savings method and has generated over 14.6M related posts on TikTok, and for good reason.

Lisa Stanley comments, “This is classic and a great way to ease yourself into the savings habit. As with so many things in life, consistency is key. By starting small, you’ll barely miss those pounds in the early weeks. A perfect way to build up savings for next Christmas—though the larger amounts towards the end of the year could be a strain, so reversing it is always an option.”

Pros: Gradual increase makes it manageable; builds consistency; significant total by year-end
Cons: Requires discipline over 52 weeks; final weeks require larger amounts (£50+ per week)

3. 365-Day 1p Challenge:

Monzo users alone saved over £360 million last year with this viral challenge. Start with just 1p on day one and add another penny each day—by day 365, you’ll have saved a surprising £667.95—that’s more than the average UK spend for a long holiday (£660, according to ABTA Travel Money’s research ).

Lisa Stanley comments: “The old saying of ‘take care of the pennies and the pounds take care of themselves’ is really evident with this challenge. Even just one year of incremental saving would grow to £667.95 over the 12 months, with the final day of the year costing you the same as a coffee, just £3.65.”

Pros: Starts incredibly small and manageable; daily habit-building; impressive final total
Cons: Daily commitment required; final months require larger daily amounts

4. No Spend Challenge: Variable

Cut out all non-essential spending for a set period, typically a month. The amount saved varies depending on your usual spending habits. This year, budgeting app Plum has released its own spin, inspired by the TikTok virality of this challenge, which has amassed 236k searches on the app in the past 7 days alone.

Lisa Stanley comments, “No-spend challenges are a good way to get to grips with budgeting. And what’s more, by considering every little purchase, it’s more sustainable too!”

Pros: Highly flexible; raises awareness of spending habits
Cons: Can feel restrictive; requires planning; savings amount unpredictable

5. Giving Up a Vice Challenge: Variable

This challenge asks you to identify one vice you can live without and deposit the money you would have spent straight into savings. For example, a £4 coffee five times a week equals £20 weekly, totalling £1,040 saved annually.

Lisa Stanley comments: “According to research, 40% of people regularly treat themselves. The pull of ‘treatonomics’ is simple: buy the small things when larger items, such as a house deposit seem unattainable. But by opting to bypass those smaller treats you can really build up a substantial amount, going some way to meeting those longer-term savings goals.”

Pros: Flexible; directly tackles spending habits; can be applied to any vice
Cons: Requires consistent willpower; may feel restrictive depending on the vice chosen

6. 20-Week Saving Challenge: £630

Save £3 in week one, then increase your savings by £3 each week. By week 20, you’ll have accumulated £630 – perfect for a short-term savings goal.

Lisa Stanley comments, “Another great way to get into the savings habit. For around the price of a weekly deal, you could build a pot worth more than £600 by the end of the challenge, a fantastic way to set aside money for holidays or festivals without even noticing.”

Pros: Shorter timeframe; achievable goal; ideal for seasonal savings (holidays, festivals)
Cons: Steeper weekly increases (up to £60 in the final week)

Lisa shares some further advice for those with saving goals this year, “For those thinking about saving this year, the best thing to do is don’t think, just do. Pick even just one of those savings challenges and stick with it, consistency is key! If you can make savings a habit, you’ll soon find you don’t even realize you’re doing it. By starting small, as many of these challenges suggest, saving will become as habitual as the daily coffee. And, at the end of the year, you’ll have a lot more to show for it!”
