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
Gross earned schedule = deposit + milestones + final earned amount; currently payable = gross earned schedule − retainage withheld; eventual project payments restore the later retainage release.
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
A 15,000 deposit, 70,000 milestones, 10,000 final earned amount and 5,000 retainage create 90,000 currently payable and 5,000 payable later, reconciling to 95,000.
Gross earned schedule = deposit + milestones + final earned amount; currently payable = gross earned schedule − retainage withheld; eventual project payments restore the later retainage release.
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
Retainage is subtracted from current payable cash and shown as a later release. Certification, withholding limits and release conditions depend on the contract and jurisdiction.
