Staggered CD maturity ladder
Staggered CD maturity ladderEqual rungs are positioned between the first and last initial maturity and the recurring event cadence.
Exact scenario comparisonNumber of ladder rungs changes while all other entered assumptions remain constant.

How to use CD Ladder Calculator
- Choose a maturity interval aligned with liquidity needs.
- Confirm each rung's actual term and rate.
- Plan reinvestment or withdrawal before every maturity.
Calculator guide
Understanding CD Ladder Calculator
A CD ladder divides capital across staggered maturities so liquidity returns in scheduled rungs rather than one distant date.
Calculation method
How the calculation works
Divide capital equally across staggered maturities and show the first and last maturity points, recurring event cadence, and an average-rate horizon illustration. Divide total deposit by rung count, multiply interval by rung number for initial maturities, estimate annual interest at the average rate, and compound the total across the horizon.
Ladder operations
Treat each maturity as a decision point
A ladder is managed repeatedly rather than set once.
Worked situations
Practical examples
- Five annual rungs create initial maturities at 12, 24, 36, 48, and 60 months.
- Equal rungs simplify allocation.
- Average-rate growth is illustrative rather than rung-specific.
Better inputs
Useful tips
- Stay within insurance limits by institution and ownership category.
- Record grace periods.
- Avoid reinvesting money needed soon.
Before relying on the result
Limitations and common mistakes
- Actual rung rates and terms are not modeled separately.
- Future reinvestment rates, taxes, penalties, callable products, and insurance aggregation are excluded.
- Annual event cadence may be fractional for unusual intervals.
Reference
Key terms
- Rung
- One deposit with its own maturity date.
- Maturity interval
- Months separating initial rung maturities.
- Ladder cadence
- Frequency at which maturities occur after establishment.
- Reinvestment risk
- Risk that future rates are lower when a rung matures.
Important note
Calculated from the entered values and stated financial terms. It is not a product quote, lending decision, tax filing, or investment recommendation.
Frequently asked questions
Are all rungs equal?
Yes in this calculator.
Does it use a different rate for each CD?
No.
What happens after the last initial maturity?
The illustration assumes the ladder continues at the entered average rate.
Are brokered CDs included?
Product-specific features are not modeled.
