Use the result for a transparent first-pass actuarial calculation when the probability, interest, exposure, and timing assumptions are already defined on a consistent basis.

Annual death probability

Probability of dying within the full year.

Fraction of years

Elapsed fraction of the year, between zero and one.

Interpolate survival within the year under a constant force of mortality. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Fractional survival probability

Probability of surviving to the fractional point within the year.

• Actuarial results are conditional on the supplied mortality, survival, loss, interest, or development assumptions. They are not a premium opinion, reserve certification, or substitute for experience analysis and regulatory judgment.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Compare the result with a second reserving, credibility, or life-contingency method and test how it changes under plausible assumption ranges. Retain the basis and valuation date with the result.
