Quick guide
How to use this calculator
- Enter amounts from the same property scenario and use consistent periods and units.
- Use visitor-entered rates and allowances from your own documents rather than assuming a local rule.
- Review the component results and the calculator-specific decision boundary before acting.
Calculation method
Calculation method
DIY cost adds vehicle, fuel, supplies, helpers, insurance, and entered time value; professional cost adds the quote, extras, packing, tips, and separately incurred time value.
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.
Worked example
Worked example
Compare a rental truck and two days of personal time against a mover quote and half a day of personal time.
DIY cost adds vehicle, fuel, supplies, helpers, insurance, and entered time value; professional cost adds the quote, extras, packing, tips, and separately incurred time value.
Supported inputs
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
Insurance scope, access conditions, inventory, delays, injury risk, and final charges require direct confirmation.
