Small Daily Savings, Big Long-Term Impact
What if you could build nearly $21,000 in 10 years, just by setting aside the cost of a daily coffee?
According to a recent analysis by Investopedia, saving $5 a day in a high-yield savings account could earn more than $2,700 in interest over a decade, based on 2025 interest rates.
That’s on top of your $18,260 in deposits, all from a simple, consistent habit.
How the Math Works
Here’s what those daily deposits could look like over time:
| Year | Deposits | Avg. Interest Rate | Earnings | Closing Balance |
|---|---|---|---|---|
| 1 | $1,825 | 4.00% | $39.86 | $1,864.86 |
| 3 | $1,825 | 4.00% | $194.92 | $5,825.63 |
| 5 | $1,825 | 2.00% | $177.11 | $9,795.23 |
| 8 | $1,830 | 3.00% | $453.39 | $16,204.89 |
| 10 | $1,825 | 3.00% | $594.10 | $20,971.68 |
(Totals: $18,260 deposited, $2,711.68 earned in interest.)
Even if interest rates change, consistently saving in a high-yield account lets compound interest do the heavy lifting, earning money on both your deposits and your growing balance.
The Power of Compound Interest
Unlike simple interest, which pays only on your deposits, compound interest means your earnings generate more earnings over time.
As financial expert Steven Rogé explains, “You earn interest on your money, then interest on your interest, and the snowball keeps rolling.”
Even modest rates can make a meaningful difference when you stay consistent. The earlier you start, the longer your money has to grow.
Choosing the Right Account
High-yield savings accounts generally pay up to 10 times more interest than traditional ones, though they may have minimum deposits or transaction limits.
When comparing accounts, look for:
- A competitive APY (annual percentage yield)
- No or low maintenance fees
- Easy online or mobile transfers
Online banks often offer higher rates because they have fewer overhead costs, so it pays to shop around.
The Bottom Line
Saving doesn’t have to be complicated. Setting aside just $5 a day — whether by auto-transfer or a weekly deposit, can help you reach major goals over time.
As Rogé puts it, “Time matters more than rate. Start the $5 habit now, then hunt for better yield when you have the bandwidth.”
Because when it comes to building wealth, consistency beats perfection, every single day.
