What this calculator estimates

Compare purchase and estimated operating cost over an ownership period. It combines the inputs below to produce Total ownership cost. Every assumption remains editable so the estimate can reflect the property, financing and location being evaluated.

Worked example

Using the displayed sample assumptions, the calculator produces $9,300. This is an illustration, not a market quote. Change one input at a time to understand what drives the result.

• Annual energy cost — sample input: 550 currency units
• Annual maintenance — optional — sample input: 100 currency units
• Ownership period — sample input: 10 years

How to interpret the result

Replace sample unit prices with current local quotes. Compare a conservative case with an expected case and keep a record of the assumptions used.
