The short answer

A retirement plan needs more than a balance target: estimate future spending, inventory guaranteed income, model savings under several return assumptions, and plan how taxes, healthcare and withdrawals interact. Revisit the inputs as life changes.

Quick answers

Common questions, answered directly

How much do I need to retire?

There is no single number. Estimate retirement spending, subtract reliable income such as Social Security or a pension, then test the remaining portfolio need across different lifespans, returns, inflation and withdrawal paths.

Should I use a 401(k) or an IRA?

They can complement each other. Compare any employer match, eligibility, tax treatment, investment menu, fees, contribution limits and withdrawal rules before deciding the order of contributions.

Does a retirement calculator predict my future balance?

No. It models assumptions. Returns, inflation, fees, taxes, contributions and retirement timing can differ materially, so use multiple scenarios and update the plan regularly.
