Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What is financial comparison?

Tap to view the answer

Financial comparison helps you evaluate different investment or savings options side by side to make informed decisions.

How is future value calculated?

Tap to view the answer

Future value is calculated using the compound interest formula: FV = PV \u00d7 (1 + r/n)^(n\u00d7t), where PV is principal, r is rate, n is compounding frequency, and t is time.

Why does compounding frequency matter?

Tap to view the answer

More frequent compounding (monthly vs annual) results in higher effective returns due to interest on interest.

Can I compare more than 2 options?

Tap to view the answer

This calculator compares two options. Run multiple calculations to compare more options.

What's the difference between APR and APY?

Tap to view the answer

APR is the nominal rate. APY (effective rate) accounts for compounding and is typically higher.

Which option is better if rates are close?

Tap to view the answer

Consider compounding frequency, fees, minimum balances, and liquidity requirements in addition to the interest rate.

How do taxes affect my returns?

Tap to view the answer

Interest income is typically taxable. Your actual after-tax return will be lower than the effective rate shown.

How to Use This Calculator

Enter Option 1

Name your first investment, enter the initial amount, annual interest rate, duration, and compounding frequency.

Enter Option 2

Do the same for the second option. You can use different amounts, rates, and times — the comparison works for any two scenarios.

Compare Results

See future values side by side, total interest earned, effective rates (APY), and which option comes out ahead.

Understanding Your Results

Future Value
What your investment will be worth at the end of the term, including all compound interest.
Effective Rate (APY)
The actual annual yield accounting for compounding frequency. More frequent compounding increases APY above the nominal rate.
Difference
How much more (or less) Option 1 returns compared to Option 2 in absolute dollars.

Key Tips

Even a 0.5% rate difference compounds significantly over longer periods.

How Financial Comparison Works

Why Compare Financial Products Side by Side?

Small differences in interest rates, compounding frequency, and time horizons can produce surprisingly large differences in final value. A 1% rate difference on $10,000 over 20 years becomes roughly $3,000 — and over 30 years, over $10,000. The calculator makes these differences visible at a glance by showing future values, interest earned, and effective rates for both options simultaneously. Use it to compare savings accounts, CDs, investment products, or any scenario where money grows at a fixed rate.

How Compounding Frequency Affects Your Return

The more frequently interest compounds, the higher your effective annual yield (APY). Annual compounding at 5% gives exactly 5% APY. Quarterly compounding at 5% yields about 5.09% APY. Monthly compounding yields about 5.12%. The differences are small at low rates and short terms but become meaningful at higher rates over decades. The calculator computes effective rates for both options so you can compare apples to apples.

Beyond the Interest Rate

The highest rate doesn't always mean the best option. Consider: fees and account minimums, early withdrawal penalties, FDIC/NCUA insurance coverage, liquidity (how easily you can access your money), and tax treatment. A 4.5% CD with a 6-month early withdrawal penalty may be worse than a 4.0% high-yield savings account with full liquidity. The calculator shows the mathematical comparison — apply your own judgment for the qualitative factors.
