Questions Fréquemment Posées — Compound Savings Calculator
What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. Unlike simple interest (calculated only on principal), compound interest grows exponentially. Einstein is often credited with calling it "the eighth wonder of the world."
How does compounding frequency affect growth?
More frequent compounding leads to slightly higher returns. For a 5% annual rate: annually gives $1,050, monthly compounding gives $1,051.16, and daily gives $1,051.27 on $1,000 after one year. The difference grows significantly over decades.
What interest rate should I use for a savings account?
High-yield savings accounts in 2024 offer 4–5% APY. Money market accounts offer similar rates. CDs (certificates of deposit) can offer slightly more for locked-in terms. Long-term investment accounts invested in stocks historically average 7–10% annually before inflation.
