About This Calculator
What Is a CD Ladder Calculator?
A CD ladder calculator divides one investment across certificates of deposit that mature at regular intervals.
A CD ladder is designed to balance access to money with the potential yields available from longer certificate terms. Instead of placing the full amount into one CD, the money is divided among several rungs with different maturity dates.
When a rung matures, the funds can be used or reinvested into a new long-term CD. Repeating that process can eventually create regular maturity opportunities while much of the ladder remains invested.
This calculator estimates the opening ladder and the first maturity value of every rung. Future reinvestment rates are not assumed.
Growth of Each Rung
Every CD is calculated independently using its deposit, APY and time to maturity.
Value = Deposit × (1 + APY)Years

Important CD Ladder Considerations
Choose Useful Intervals
Monthly, quarterly, six-month or annual spacing can be selected based on how often access may be needed.
Check the Actual Rate Curve
Longer CDs do not always pay more. Use zero or a negative APY step when rates are flat or inverted.
Review Withdrawal Rules
Keep emergency cash outside the ladder when early access could trigger a penalty.
Frequently Asked Questions
CD Ladder Calculator FAQs
A CD ladder is a group of certificates of deposit with staggered maturity dates, creating periodic access while other money remains invested.
The number depends on the investment amount, minimum deposit requirements and desired maturity frequency. This tool supports two through ten rungs.
It is the percentage-point adjustment applied to every next rung. For example, 0.15 adds 0.15 percentage points to each longer term.
Yes. Enter a negative APY change when longer available terms pay less than shorter terms.
No. It calculates the opening ladder and the first maturity value of each rung because future rates are unknown.
No. Results depend on the APYs entered and the institution's actual terms, fees, penalties and tax treatment.
Note: This calculator provides planning estimates only. It does not model changing rates, future reinvestment, early-withdrawal penalties or institution-specific fees.
