Frequently Asked Questions: Return on Investment (ROI) Calculator

Answers to common questions regarding inputs, calculations, and mathematical methodology.

Why is annualized ROI more useful than simple ROI?

A 50% return over 1 year is extraordinary, whereas a 50% return over 10 years represents a modest ~4.1% annual return.

Does this account for ongoing maintenance expenses?

You can factor recurring expenses into the total initial cost or subtract them from final return value.
