Frequently Asked Questions

APR is the simple annual interest rate. APY (Annual Percentage Yield) includes the effect of compounding. APY is always equal to or higher than APR and represents your true annual return.

Most savings accounts compound daily. Some compound monthly or quarterly. Daily compounding earns slightly more than monthly or quarterly compounding at the same APY.

As of 2024, high-yield savings accounts offer 4-5% APY. Traditional bank savings accounts may offer 0.01-0.5%. Online banks typically offer the highest rates.

Key Assumptions & Notes

Compounding: Interest is calculated and added to the balance at the selected compounding frequency. Daily compounding yields slightly more than monthly or yearly.

APY vs APR: APY (Annual Percentage Yield) already accounts for compounding effects. This calculator uses APY directly applied at the compounding frequency for simplicity.

Inflation: The inflation-adjusted value shows what your future savings would be worth in today's purchasing power. Default is 3% annual inflation.

Disclaimer: This calculator provides estimates for educational purposes only. Actual returns may vary. Interest rates can change. Savings account rates are variable and not guaranteed. FDIC insurance covers up to $250,000 per depositor per institution.
