Each rung is calculated independently with A = P(1 + r/n)nt and runs entirely in your browser. Reinvestment of maturing rungs is not assumed.

A resposta rápida
A CD ladder splits one deposit across several CDs with staggered maturity dates, so part of the money comes free at regular intervals while the rest keeps earning longer-term rates. Divide the total by the number of rungs, assign each rung a term stepping evenly up to the longest, and compute each with A = P(1 + r/n)^(nt). The ladder's blended APY is the deposit-weighted average of the rung rates, not a simple average, so an unequal ladder tilts toward whichever rungs hold the most money. The point of a ladder is that it removes the timing decision: you are neither betting that rates will fall by locking everything long, nor giving up yield by keeping everything short. As each rung matures you either take the cash or roll it into a new longest rung, which keeps the cycle going.
Fórmula e método
Blended APY = Σ (rateᵢ × amountᵢ) ÷ total deposited
Each rung's rate weighted by the dollars in it gives the ladder's overall yield.
Divide your total deposit by the number of rungs to size each CD.
Assign staggered terms — 5 rungs over 60 months means 12, 24, 36, 48 and 60 months.
Look up the bank's rate for each term and enter it per rung.
Calculate each rung independently with A = P(1 + r/n)^(nt).
Sum the maturity values for the ladder total, and weight the rates by amount for the blended APY.
Guia
The full sum you want laddered. The tool splits it evenly across the rungs you choose.
Four or five is typical. More rungs mean more frequent access to cash but smaller individual CDs.
This anchors the ladder. Terms step evenly from the shortest rung up to this maximum.
Enter your bank's actual rate for each term. Longer rungs usually pay more, and the ladder diagram redraws as you type.

Resultado
You capture most of the 5-year rate while still freeing $10,000 plus interest every twelve months.
Metodologia
Rungs are funded on the same day and sized equally — uneven ladders are possible but change the blended yield.
Rates shown per rung are the bank's current rates for those terms; real rates change between rungs maturing.
The model does not assume reinvestment. In practice you would roll each maturing rung into a new long-term CD.
Each rung is a separate CD with its own early withdrawal penalty.
As convenções seguem a Regulation DD (12 CFR 1030), que rege como as instituições dos EUA divulgam o APY em contas de depósito. Depósitos em instituições seguradas têm proteção do FDIC de até $250,000 por depositante, por banco, por categoria de titularidade.

Detalhes
Laddering reduces interest-rate risk: if rates rise you reinvest a rung soon; if they fall your long rungs stay locked at the old higher rate.
Once a ladder is mature, rolling each maturing rung into the longest term means you eventually earn long-term rates on everything while still having annual access.
A 'barbell' variant puts money only in the shortest and longest terms; a 'bullet' targets one future date with several CDs maturing together.
FDIC insurance covers $250,000 per depositor per bank — a large ladder can be split across institutions to stay fully covered.

Aplicações
You want a rung maturing every year to cover annual expenses without touching the rest.
You do not want to bet on rates going up or down, so you hedge across terms.
You want better-than-savings yield but need part of the money reachable without a penalty.

A CD ladder splits one deposit across several CDs with staggered maturity dates, so part of the money frees up at regular intervals while the rest keeps earning longer-term rates. Divide the total by the number of rungs and assign each rung a term stepping evenly up to the longest. Put $50,000 into five rungs of $10,000 at 12, 24, 36, 48 and 60 months, paying 4.30%, 4.40%, 4.50%, 4.55% and 4.60% APY respectively, and the ladder returns $57,210.61 — $7,210.61 of interest — with a money-weighted blended yield of 4.47%. As each rung matures you either take the cash or roll it into a new longest rung, which keeps the cycle running. The point is that it removes the timing decision: you are neither betting rates will fall by locking everything long, nor giving up yield by keeping everything short.
