UDD Fractional Survival Calculator
Interpolate survival within the year under the uniform distribution of deaths assumption.
Description
Interpolate survival within the year under the uniform distribution of deaths assumption.
UDD Fractional Survival Calculator provides a focused, reproducible calculation with explicit inputs and a deterministic result. Interpolate survival within the year under the uniform distribution of deaths assumption.
Use to interpolate survival within a year under the uniform distribution of deaths assumption.
When to use UDD Fractional Survival Calculator
Use to interpolate survival within a year under the uniform distribution of deaths assumption.1
How the calculation works
Interpolate survival within the year under the uniform distribution of deaths assumption.2
t p = 1 − t q, for 0≤t≤1 1Inputs and interpretation
Keep every input on the same valuation, timing, unit, and assumption basis. Interpret the output at the precision supported by those inputs rather than treating extra decimal places as additional certainty.
Limitations and assumptions
UDD is a within-year convention, not evidence that deaths are actually uniform, and it applies only inside the table year.
