Input defaults that are not sourced measurements are illustrative planning assumptions. Exact unit definitions, the 52-week convention and algorithm details are in the shared methodology.
Worked example
An example you can inspect.
A $4,577 equipment quote plus your entered $1,500 assembly allowance totals $6,077 before all unquoted items. The assembly figure here is an arithmetic input, not a sourced labor estimate.
Build scenarios from comparable scope.
The product observations are named, dated examples of advertised prices. They are not a distribution of installed project costs. Start by selecting a product only if it is relevant to your project, then obtain quotes for the remaining lines. For each line, enter low, likely and high values that describe the same scope. A lower quote excluding delivery is not directly comparable with a higher quote including delivery. Record the exclusions before using either number in a scenario.
Understand a partial total.
An untouched line remains unquoted and excluded, rather than being silently priced at zero. Enter all three scenario values for a line or clear it completely. If only one or two values are present, the tool asks for completion so a partly entered line cannot disappear into the total. A low-to-high interval is your scenario range, not a statistical confidence interval. The likely column is also your assumption; the calculator does not assign it a probability.
Revisit the budget when the design changes.
Indoor or outdoor setting, finish tier and planned users are quote context. They do not trigger undocumented price multipliers. If those choices change the work, replace the affected quote values and check the scope again. Permits, site preparation, electrical work, installation and delivery can involve different suppliers and exclusions. The completed worksheet is useful for comparing a defined set of assumptions, but even every filled line cannot establish that the list covers every cost of your particular project.
Questions, considered
Questions about this tool
How should I interpret the total cost estimator result?
Standard, premium and bespoke organize your quotes; they do not apply invented finish multipliers. Size/location/type describe scope and do not scale a kit price automatically. Build low, likely and high project budgets from dated equipment examples and your own itemized quotes, with exclusions shown clearly.
Which assumptions matter in the total cost estimator?
Sum each entered low/likely/high column across the equipment and project-scope line items. Low ≤ likely ≤ high is required for every line. Product observations apply to their named configuration and date. They are not a price-per-area formula, market percentile or installed quote. Unquoted electrical work, permits, delivery, site preparation, finishes and tax leave the result marked partial. Enter tax as an actual quoted dollar line.
