Sources & Official References

We prioritize primary sources for time-sensitive retirement information. Country pages link directly to the government, social-insurance or pension authority used for that profile. U.S. account calculators link to the IRS and Social Security calculators link to the Social Security Administration.

Why primary sources matter

Retirement rules can change by year, birth cohort, contribution history or employment category. A primary source is more reliable for those details than a generic summary.

How sources are used

Sources support statutory facts and limits; they do not guarantee that a general calculator can determine an individual’s official benefit without the records required by that authority.
