📅 Term & Rate — Certificate of Deposit (CD)

Enter the stated rate your bank quotes (sometimes just called "Rate"). The calculator computes your true effective yield — the APY / AER — automatically below, so you never have to compound it yourself.

🏦 Tax Treatment

Interest earned in a standard/taxable account is reported to you (e.g., US Form 1099-INT) and taxed as ordinary income in the year it's credited — even if you don't withdraw it. Your bank does not withhold this tax from your CD; you pay it separately using other funds, so your CD balance itself is never reduced by taxes.

➕ Add-On CD / Recurring Deposit Top-Ups (optional)
Most standard CDs are lump-sum only — once opened, you can't add more money until maturity. This section is for the exceptions: US "add-on CDs," Indian Recurring Deposits (RDs), or any regular-deposit plan that does accept ongoing contributions. Leave this at $0 for a normal, one-time CD/GIC/FD deposit.

How to Use This Calculator

  1. Pick your region and country — this sets the right currency, local terminology (CD, GIC, FD, or Term Deposit), and the correct deposit insurance scheme for that country.
  2. Enter your initial deposit — the lump sum you're putting into the CD when you open it.
  3. Set the term and the stated interest rate — use the exact rate your bank quotes (not their advertised APY). The calculator works out the true APY for you.
  4. Choose the compounding frequency — check your CD's disclosure statement; most US CDs compound daily or monthly.
  5. Pick your tax treatment — Standard/Taxable for a regular brokerage or bank CD, Tax-Deferred for a Traditional IRA/RRSP-held CD, or Tax-Free for a Roth IRA/TFSA/ISA-held CD.
  6. Only fill in "Add-On" contributions if your product actually allows ongoing deposits (rare for a standard CD, common for Recurring Deposits).
  7. Check your results — the maturity value, effective APY, growth chart, deposit insurance coverage, and early withdrawal penalty estimate all update instantly.
  8. Export — download a PDF summary to keep for your records, or an Excel file with the full period-by-period schedule.

Want the full explanation? Simple vs. compound interest, APY vs. the stated rate, how compounding frequency changes your return, worldwide deposit insurance limits, early withdrawal penalties, IRA/TFSA/ISA tax treatment, and the CD ladder strategy are all covered in depth in our CD Calculator Guide 2026.

This calculator provides estimates for general informational purposes only and is not financial, tax, or legal advice. Actual bank/institution terms, compounding conventions, and early withdrawal penalties vary by product and provider — always confirm exact terms in your CD, GIC, FD, or Term Deposit's disclosure statement before depositing. Deposit insurance limits shown reflect published scheme rules as of mid-2026 and may change; verify current limits with the relevant scheme (FDIC, CDIC, FSCS, DICGC, FCS, or DCS) before relying on them.
