Define a retirement goal

Retirement planning starts with a target. Your goal may depend on expected spending, retirement age, lifestyle, healthcare needs, inflation, and other income sources.

Because the future is uncertain, it is useful to test multiple savings targets instead of relying on one fixed number.

Estimate years left to save

The time between your current age and retirement age is one of the biggest drivers of the projection. More years can give contributions and investment growth more time to compound.

Compare contributions and growth

A retirement calculator can separate total contributions from potential investment growth. That breakdown helps you understand whether increasing contributions, extending the timeline, or changing assumptions may close a shortfall.
