Not a professional estimate
Examples and calculators do not inspect your scope, contracts, drawings, market conditions, labour agreements, technical requirements, accounting policies or risk register. They cannot determine the appropriate budget for a real project.
No accounting, tax, legal or engineering advice
Terms such as capital cost, expense, reserve and allocation are explained in a project-planning context. Their formal treatment depends on applicable standards, laws, contracts and facts. Obtain qualified advice where consequences are material.
No current-price guarantee
The site deliberately avoids universal price claims. Costs vary by date, location, scale, procurement, currency, quality, schedule and market conditions.
Formula limitations
Simple formulas are useful for learning and first-pass scenarios. Earned-value, PERT, lifecycle-cost and allocation calculations may require more sophisticated methods, correlation, tax treatment, probability analysis or organizational rules.
