About High-Yield Savings & CD Calculator
In a high-interest rate environment, holding idle cash in a traditional bank account paying 0.01% incurs massive purchasing power erosion. ConvertSheet's High-Yield Savings & CD Calculator models your cash yields across both liquid savings accounts and fixed-term CDs. Compare daily versus monthly compounding, test the financial cost of CD early withdrawal penalties (typically 90 to 180 days simple interest), and export your entire month-by-month compounding schedule directly to Microsoft Excel (.xlsx).

Frequently Asked Questions: High-Yield Savings & CD Calculator
Answers to common questions regarding inputs, calculations, and mathematical methodology.
What is the difference between APR and APY?
APR (Annual Percentage Rate) reflects the simple annual interest rate without compounding. APY (Annual Percentage Yield) reflects the true annual return taking into account how often interest compounds (daily or monthly), meaning APY is always slightly higher than APR.
How do CD early withdrawal penalties work?
If you withdraw funds from a Certificate of Deposit before its maturity date, financial institutions penalize you by forfeiting a set number of months of interest (commonly 90 days for short-term CDs or 180 days for multi-year CDs), deducted from earned interest or principal.
Is daily compounding significantly better than monthly compounding?
Daily compounding yields slightly more interest because accrued interest begins earning its own interest 24 hours later rather than at the end of each month. On a $10,000 balance at 5.0% APY, the difference is approximately $1 to $2 per year.
