Free Government Tools & Calculators

How to use these government calculators

These tools cover the most common calculation tasks across federal, state, and local government work. Whether you are a contracting officer building a bid cost estimate, a federal employee checking your FERS retirement date, or a local finance director projecting next year's property tax revenue, each calculator uses the underlying formulas and published standards that govern public sector finance.

Federal employment and pay

The GS Pay Scale Calculator applies current locality pay tables to your grade and step. You get total annual pay, the applicable locality area, and a breakdown between base and locality components. It updates annually following OPM's January release.

Property tax and local government revenue

Property tax is set at the local level and varies widely by jurisdiction. The property tax calculator converts mill rates and assessed values into annual tax bills, with optional inputs for homestead, senior, and disability exemptions. Use the mill rate tool to convert between mill rates and effective percentages.

Federal procurement and contracting

Federal procurement follows FAR cost accounting rules. The procurement tools here calculate indirect cost rates, total cost of ownership for bids, and overhead absorption under DCAA-accepted costing methods. These are the same formulas used in incurred cost submissions and pricing proposals.
