Why use the Professional Fees and Preliminaries Calculator?

Build percentage and fixed allowances for professional fees, contractor preliminaries, overhead, permits and other soft costs. It organizes the entered operating or development records on a consistent basis before a team reviews budgets, funding, performance, or feasibility.

The calculation

Each percentage allowance applies to the entered base named by the visitor; total soft cost adds fixed allowances.

Worked development scenario

5% professional fees and 8% preliminaries on 5,000,000 hard cost add 650,000 before fixed allowances.

What the result does not decide

Percentage bases differ by contract and estimate; this calculator uses the visible hard-cost basis only. The result does not verify market demand, valuation, construction scope, funding availability, accounting treatment, planning approval, or investment suitability.

Quick guide

How to use this calculator

  1. Enter amounts from the same property scenario and use consistent periods and units.
  2. Use visitor-entered rates and allowances from your own documents rather than assuming a local rule.
  3. Review the component results and the calculator-specific decision boundary before acting.

Calculation method

Calculation method

Each percentage allowance applies to the entered base named by the visitor; total soft cost adds fixed allowances.

Entered fixed decimals remain exact through rational arithmetic. Planar distance outputs that require square roots use bounded numerical evaluation. Values round only for display, and unsupported or undefined states return an explicit message.

Precision and limits

International scope

No currency, market price, interest rate, tax, tenancy rule, planning code, lender policy, or measurement definition is supplied automatically.

Scenario, not a decision

Results are arithmetic scenarios from visitor-entered values—not an appraisal, loan approval, legal interpretation, planning determination, forecast, or professional recommendation.

Precision and privacy

Inputs accept bounded plain decimals and remain in this browser. The engine prevents invalid denominators and misleading non-finite results.

Calculator-specific boundary

Percentage bases differ by contract and estimate; this calculator uses the visible hard-cost basis only.
