Frequently Asked Questions
What is APY and how is it different from interest rate?
APY (Annual Percentage Yield) includes the effect of compounding over a year, while a nominal interest rate does not. This calculator uses APY directly so the result already reflects compounding — no extra adjustment needed on your part.
How often is interest compounded in this calculator?
Interest is compounded monthly. The monthly rate is derived from the APY you enter, so the projected balance closely mirrors a standard high-yield savings account or money-market account that credits interest each month.
What if I start with $0 initial deposit?
That is perfectly valid — enter 0 in the Initial deposit field. The calculator will project growth based purely on your monthly contributions and the APY you specify.
Does the calculator account for taxes on interest?
No. The figures shown are pre-tax projections. Interest earned in a regular savings account is typically taxable income. Consult a tax adviser to understand the impact on your actual take-home returns.
How can I maximise my savings growth?
Three levers matter most: (1) starting as early as possible to benefit from compounding, (2) choosing a high-yield account with the best available APY, and (3) automating a regular monthly deposit so contributions never get skipped.
Can I use this for a CD (Certificate of Deposit)?
Yes. Enter the CD's APY and its term length. Leave the monthly deposit as $0 if no additional contributions are allowed during the CD term. The ending balance in the schedule will match your expected maturity value.
