Saving money is one of those things that’s simple in theory and difficult in practice. Not because people don’t understand compound interest or the value of an emergency fund. But because the reward structure is backwards. You give up something enjoyable now in exchange for something abstract later. Your brain isn’t wired to find that exciting.
Gamification tries to fix the reward structure. And unlike a lot of behavioral interventions that sound good in theory, this one has actual data behind it.
The prize-linked savings experiment
The most compelling research on gamification and savings comes from prize-linked savings accounts, or PLSAs. These are savings products where, instead of earning traditional interest, your deposits enter you into a lottery-style drawing for cash prizes. You don’t lose your principal. You just trade predictable interest for a chance at a larger payout.
Peter Tufano at Harvard Business School studied PLSAs extensively, particularly in South Africa where they’ve been available for decades. The results, published in Management Science, showed something striking.
Individuals who used prize-linked savings accounts increased their total savings by an average of 38% compared to their baseline savings level, roughly 1% of annual income in additional deposits.
That’s a meaningful increase from a simple reframe. The money is going to the same place (a savings account), but the experience of depositing it feels fundamentally different. Instead of watching a balance inch upward, you’re entering a drawing. The savings behavior is identical. The psychological experience is not.
Importantly, the research found that prize-linked deposits did not cannibalize regular savings. People weren’t just moving money from one account to another. They were saving more in total. The lottery-style element also appeared to substitute for actual lottery gambling, which means some participants were redirecting money from a pure loss (lottery tickets) into actual savings.
The first large-scale PLSA program in the United States launched in 2009 in Michigan, called “Save to Win.” Of the initial participants, 56 percent were non-savers before the program, people who had no savings habit at all. The lottery mechanic gave them a reason to start.
Why variable rewards work so well
The psychology behind this isn’t complicated, but it is deeply wired. It comes down to how your brain’s reward system handles uncertainty.
Under a fixed reward schedule (save $500, earn $2 in interest), your brain quickly habituates. The reward is predictable, so it stops generating much of a dopamine response. You know exactly what you’re going to get, and “exactly what you expected” is not exciting to a nervous system that evolved to pay attention to surprises.
Research on reinforcement schedules shows that variable ratio rewards, where the payoff is unpredictable, produce the most persistent behavior and are the most resistant to extinction, even after rewards stop.
Variable ratio reinforcement is why slot machines are more engaging than vending machines, even though vending machines have a better expected return. Your brain releases dopamine not when you receive the reward, but when you anticipate a reward you’re uncertain about. That anticipation signal, “something good might happen,” is what drives repeated behavior.
Prize-linked savings accounts tap into this mechanism directly. Every deposit is a lottery entry. You might win $25. You might win $10,000. You probably won’t win anything this time. But you might. That “might” is doing more motivational work than any interest rate ever could.
Beyond lotteries: what other gamification elements work
Prize-linked savings are the most studied form of savings gamification, but they’re not the only one. Commonwealth, a financial innovation nonprofit, has tested several gamified approaches.
In one study, Walmart MoneyCard users who were offered the chance to win cash prizes for saving ended up saving 35 percent more on average a year after the initiative launched. Commonwealth also developed SavingsQuest, an app that uses challenges, badges, and messaging to motivate small savings transfers between checking and savings accounts.
The broader gamification research, mostly from educational contexts, shows moderate positive effects. A meta-analysis by Sailer and Homner (2020) found an overall effect size of g = 0.49 for gamification on learning outcomes. While that’s not directly about savings, it tells us that game-like elements meaningfully change behavior across domains. The effect isn’t trivial.
The specific elements that seem to matter most for financial behavior are:
Progress visibility. Seeing a progress bar move toward a goal activates the same “goal gradient” effect that makes you walk faster as you approach the end of a hallway. The closer you get, the more motivated you become. This is why showing “$2,300 of $5,000 saved” with a visual bar works better than just showing a balance.
Milestone celebrations. Small acknowledgments when you hit intermediate targets (saving your first $500, making 10 consecutive deposits, reaching 50 percent of your goal) provide the periodic reinforcement that keeps behavior going between the start and the end.
Social proof. Knowing that others are saving alongside you, even anonymously, creates a normative pull. “People like you saved an average of $340 this month” is more motivating than most people would expect.
Streaks. Consecutive-deposit tracking leverages loss aversion. Once you’ve saved for 15 weeks straight, breaking the streak feels like losing something, not just failing to gain something. Loss aversion is roughly twice as strong as the equivalent gain, per Kahneman and Tversky’s prospect theory.
Where gamification falls short
None of this means gamification is a magic fix. There are real limitations.
The first is novelty decay. Many gamification elements lose their power over time as the brain habituates to them. The first badge feels rewarding. The fifteenth feels like clutter. Well-designed systems address this by introducing new challenges or escalating goals, but poorly designed ones just stack up meaningless rewards until users stop paying attention.
The second is that gamification works best as a complement to a clear goal, not a substitute for one. Badges and progress bars are motivating when they’re tracking progress toward something you actually want: a house down payment, an emergency fund, a vacation. Without a meaningful underlying goal, gamification can feel like a hollow exercise. The game elements provide the “how” of motivation; the goal provides the “why.”
The third is that the most effective gamification mechanic, variable rewards, can cross the line into manipulation if used irresponsibly. The same mechanism that makes prize-linked savings effective is what makes gambling addictive. The difference is whether the variable reward is layered on top of genuine value creation (saving money you keep) or value extraction (gambling money you lose). Intent and design matter.
What this means in practice
If you’ve ever tried to save money and found it boring (which is most people, most of the time), the problem isn’t your discipline. It’s the feedback loop. Traditional savings offers almost no positive reinforcement between “I decided to save” and “I reached my goal,” which might be months or years away. That’s a long time to sustain motivation on willpower alone.
The research suggests you don’t have to. Small, frequent signals of progress (a visual tracker moving forward, a milestone acknowledgment, even just seeing your balance update in real time) give your brain the periodic reinforcement it needs to maintain the behavior.
You don’t need to trick yourself into saving. You just need a system that makes the progress feel real while it’s happening, not only after it’s done.
