Watch your money
work for you
See how compound interest turns your savings into wealth — and how many hours of work your interest earns for you.
You'll reach 84% of your goal. Try increasing your monthly contribution or extending the time period to reach $100,000.
Compound interest earned you $18,717 — that's like working 4mo 7d for free. Your money earned 29% extra on top of what you deposited.
The magic of compound interest
Albert Einstein reportedly called compound interest the eighth wonder of the world. Whether or not he actually said it, the sentiment is accurate. Compound interest means you earn interest not just on your initial deposit, but also on all the interest you've already earned. Over time, this creates exponential growth. A $10,000 deposit earning 5% annually becomes $16,289 after 10 years, $26,533 after 20 years, and $43,219 after 30 years — without adding a single extra dollar. When you add regular monthly contributions, the results become truly remarkable.
Our Savings Calculator converts this growth into hours of work — showing you how much "free" labour your money performs through compound interest. If your savings earn $20,000 in interest over 20 years and you earn $25 per hour, that's 800 hours of work your money did for you. That's nearly 5 months of full-time employment — earned while you sleep.
How compound frequency affects your savings
The frequency at which interest is compounded affects your total returns. Daily compounding earns slightly more than monthly, which earns more than quarterly, which earns more than annually. The difference is most noticeable with larger balances and higher interest rates. Most savings accounts compound daily or monthly. Our calculator lets you compare all four frequencies so you can see the exact impact on your savings.
Tips for building your savings
The most important habit is consistency. Set up automatic transfers to your savings account so you never forget. Start with whatever you can afford — even $50 per month adds up significantly over time. Use high-yield savings accounts that offer competitive interest rates (currently 4-5% at many online banks). Keep an emergency fund covering 3-6 months of expenses in an easily accessible account. Once your emergency fund is established, consider directing additional savings toward investments for higher long-term returns.
Frequently Asked Questions
How much should I have in savings?
A good starting goal is an emergency fund covering 3-6 months of essential expenses. After that, your savings goals depend on your situation — a house down payment, retirement, education, or other goals. The most important thing is to start saving consistently, regardless of the amount. Our calculator helps you set realistic goals and track your progress.
What's the difference between APR and APY?
APR (Annual Percentage Rate) is the simple interest rate without compounding. APY (Annual Percentage Yield) includes the effect of compounding. APY is always equal to or higher than APR. When comparing savings accounts, look at the APY for a more accurate picture of what you'll actually earn. Our calculator uses APR and lets you select your compound frequency to calculate the effective APY.
Should I save or pay off debt first?
If you have high-interest debt (like credit cards at 15%+), paying it off typically provides a better return than any savings account. However, having a small emergency fund ($1,000-$2,000) prevents you from taking on new debt when unexpected expenses arise. A balanced approach is: small emergency fund first, then aggressive debt payoff, then full savings.
How does inflation affect my savings?
Inflation erodes your purchasing power over time. If inflation is 3% and your savings earn 2%, you're actually losing 1% in real value each year. This is why it's important to seek savings rates that at least match inflation. For long-term goals (10+ years), investing in diversified stock market index funds has historically outpaced inflation significantly.
