Calculation basis and official references

Reviewed on:

Formula basis

Expected total = annual pension × expected years. Expense ratio = premiums ÷ expected total, rounded up to 1 percentage point and capped at 100%; miscellaneous income = annual pension − floored annual expense.

Calculation method

This calculator estimates payment years from annuity type, term, starting age, and gender, then allocates paid premiums to annual necessary expense and miscellaneous income.

Exclusions and checks required

  • For life and term annuities, expected years come from the calculator’s own gender-and-age life-expectancy approximation, not Japan’s statutory tax life-expectancy table.
  • Owner, premium payer, and recipient differences, inheritance or gift tax, post-guarantee treatment, and withholding are not determined.
