Balance = Initial × (1+r)^n + Monthly × ((1+r)^n − 1) / r
Compound interest is calculated monthly. APY (Annual Percentage Yield) already accounts for compounding, so the monthly rate is APY / 12.
As of 2026, high-yield savings accounts offer 4-5% APY. Traditional bank accounts typically offer 0.01-0.5%. Online banks generally offer the highest rates.
Most savings accounts compound interest daily or monthly. APY accounts for this compounding, so you can use APY directly in calculations regardless of compounding frequency.
