New Zealand Retirement Calculators

Free, localized retirement planning tools updated for the 2026 financial year in New Zealand.

New Zealand keeps circling compulsory KiwiSaver, and the calculator here prices the debate with one career's numbers: enrolment from the first payslip at 18 versus the delayed start that voluntary systems actually produce. The gap, roughly $270,000 at 65 on an ordinary salary, is mostly lost compounding rather than lost contributions, which is both the policy argument and a personal warning about savings suspensions and late enrolment.
