FIRE Retirement Calculator: frequently asked questions

What is the 4% rule?

It is a common guideline that a portfolio may support withdrawing about 4% per year. The calculator uses it as a starting point, and you can change the rate.

Can I plan for a partner too?

Yes. Combine both incomes and savings, or keep separate copies to compare.

Is the projection guaranteed?

No. Returns are estimates. Use it for planning and talk to a qualified advisor before major decisions.

How do I get my files?

Right after payment you receive a download link at the email you entered at checkout. Save the files to your device and use them as often as you like.

Is anything shipped to me?

No. This is a digital product, so nothing physical is mailed.

Is this professional advice?

No. This product is for education and personal organization. For medical, tax, legal or financial decisions, please talk to a qualified professional.
