Open Mercato TCO Calculator

Transparent TCO model

Values are entered by the user from their own quotes and estimates. The model does not provide a price list, quote, or financial advice. It excludes taxes, inflation, discounting, and exchange rates.

A blank field means the estimate is unknown. Enter 0 for a confirmed zero cost or an item that does not apply. The full result appears once every item has an estimate.

Choose a scenario scope

A scenario only sets the horizon and displays explicit scope assumptions. It leaves cost fields unchanged.
