Calculator FAQs

Are these retirement calculators really free?
Yes. Every calculator on RetirementCalculator.net is completely free to use with no registration required. The site is supported by advertising, which is always separated from calculator results and editorial content.
How accurate are online retirement calculators?
Online calculators are planning tools, not predictions. They project outcomes based on the assumptions you provide (rate of return, inflation, savings rate). Our calculators use established financial formulas and publicly documented assumptions. The value is in comparing scenarios and understanding which variables matter most, not in treating any single number as a guarantee.
Which calculator should I start with?
Start with the Retirement Calculator on our homepage. It gives you the broadest picture: projected savings, income gap, readiness score, and trajectory chart. From there, explore account-specific calculators (401k, Roth IRA) to optimize individual accounts.
What data sources do you use?
All calculators are built on publicly available data from the IRS, Social Security Administration, and major financial research institutions like Vanguard and Fidelity. Every default assumption is documented on our methodology page.
Do I need to create an account?
No. All calculators work instantly in your browser with no account, no email, and no personal data collection. Your inputs stay on your device. If you want to save results, you can bookmark the URL (inputs are saved in the page address) or use the email export feature.
How often are contribution limits updated?
The IRS announces new contribution limits in October or November each year for the following calendar year. We update all calculators within 24 hours of the official IRS announcement. Every page shows a "Last Updated" date so you can verify currency.
