How does compound interest work?

Compound interest is interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods. This 'interest on interest' effect is why money grows much faster over time.

How often is interest compounded in this calculator?

This calculator compounds interest monthly. The annual interest rate you enter is divided by 12 and applied to your balance each month, which is a common scenario for savings accounts and investments.

Should I prioritize paying off debt or saving?

Generally, you should prioritize paying off high-interest debt first, as the interest you pay is likely higher than the interest you can earn by saving. However, maintaining a small emergency fund simultaneously is wise.

How much should I save each month?

A popular guideline is the 50/30/20 rule: 50% for needs, 30% for wants, and 20% for savings. The ideal amount depends on your goals, income, and lifestyle. Use this calculator to model different savings scenarios.

What's the difference between APY and APR?

APR is the simple annual interest rate, while APY includes the effects of compounding, providing a more accurate measure of your real return.

How does inflation affect my savings?

Inflation reduces purchasing power over time. To grow your savings in real terms, your interest rate should exceed the inflation rate, which is your 'real rate of return.'

What is a high-yield savings account?

A high-yield savings account offers a significantly higher interest rate than traditional savings accounts, making it a good option for emergency funds or short-term goals.

What are common savings pitfalls to avoid?

Pitfalls include lifestyle inflation, high-interest debt, and emotional spending. Automating your savings and maintaining a clear budget helps avoid these issues.

How can I increase my savings rate over time?

Increase your savings rate by 1% every six months or with each pay raise, and review your budget regularly for potential expense reductions.

Are the calculator results guaranteed?

No, results are projections based on your inputs and are not guaranteed, as actual returns may vary due to market conditions, fees, and other variables.

Diving Deeper into Compound Interest

Albert Einstein famously called compound interest the “eighth wonder of the world.” Our savings calculator is built on this powerful principle. But what makes it so effective? It’s the concept of “interest on interest.”

With simple interest, you only earn interest on your initial principal. With compound interest, the interest you earn is added back to your principal, and you start earning interest on the new, larger amount. This difference becomes dramatic over longer periods and with more frequent compounding, such as monthly.

The Rule of 72

A handy shortcut to estimate how long it will take for your investment to double is the “Rule of 72.” Simply divide 72 by your annual interest rate. For example, at an 8% annual return, your money would double in approximately 9 years (72 / 8 = 9). This rule of thumb provides a quick way to grasp the long-term power of your interest rate.

Practical Savings Strategies

Automate Contributions

The easiest way to save consistently is to “pay yourself first.” Set up automatic transfers from your checking to your savings account each payday.

Set Specific Goals

Saving is more motivating with a clear target. Use our calculator to see what it takes to reach goals like a house down payment in 5 years.

Optimize Interest Rates

Don’t let money sit earning 0%. Research high-yield savings accounts or low-cost index funds to maximize returns for your goals.
