Split savings across equal CD ladder rungs with stepped terms and APYs to see interest per rung and a blended yield.

CD ladders balance liquidity and rate lock—useful when rising rate environments make long single CDs feel risky. Shorter front rungs fund near-term expenses.

Auto-renewing rungs without comparing new market rates can leave money in stale APYs.

Taxes on interest continue annually even when reinvested—plan withholding or quarterly estimates.

How to use this tool

Enter total amount, number of rungs, shortest term, base APY, and APY step between rungs. Optionally set a reinvestment horizon in years and early-withdrawal penalty months.

Worked example

A $50,000 five-rung ladder starting at 12 months / 4% APY with 0.25% steps shows per-rung interest and a blended yield. Over a 10-year horizon with rolling reinvestment, ending value exceeds one cycle; a 3-month early-withdrawal penalty estimates interest forfeited if you break the ladder.

When to use this

  • Building emergency fund tiers with FDIC-insured products.
  • Retirees scheduling known cash needs across years.
  • Capturing rate increases without committing entire balance to one term.

Common mistakes

  • Creating too many small rungs below bank minimum CD sizes.
  • Breaking ladder discipline to chase stock market timing.
  • Ignoring early withdrawal penalties on unexpected expenses.

How it works

Splits capital into equal CD rungs with stepped terms and APYs, reporting interest per rung and a blended APY. Optionally rolls each rung’s principal and interest over a multi-year horizon and estimates an early-withdrawal penalty as months of interest forfeited.

Limitations

Estimates only for educational purposes. Not financial, tax, or legal advice. Verify figures with your lender, advisor, or official IRS/SSA sources before making decisions.
