How to use this category

Accounting calculations without heavy software

FreeToolLabs accounting tools are designed for focused calculations when you do not need a full bookkeeping platform.

Profit and cost accounting tools

Start with the COGS Calculator to estimate cost of goods sold from inventory activity, then use the Profit Calculator and Margin Calculator to connect costs with revenue and pricing. The Break-Even Calculator adds contribution margin and the sales volume required to cover fixed costs.

These tools are useful for product pricing, ecommerce, retail, service packages, project economics, and basic management reporting. Each tool has one canonical page even when it is relevant to more than one category.

Tax and payroll tools for US and Canadian planning

Use the Sales Tax and Income Tax calculators for estimates, the GST/HST Calculator to add or extract a user-entered Canadian transaction-tax rate, and the Payroll Cost Calculator to estimate employer costs beyond gross wages. Salary and Paycheck tools remain available for compensation planning.

Tax and payroll rules vary by jurisdiction and can change, so these pages keep rates transparent and editable instead of pretending one default applies everywhere. Verify final compliance amounts against current official rules and records.

Cash flow and liquidity analysis

The Cash Flow Calculator summarizes operating, investing, and financing cash movement. Working Capital, Current Ratio, and Quick Ratio calculators turn balance-sheet values into liquidity measures that can be tracked over time. Budget and Net Worth tools provide additional planning views.

These tools are most useful when the inputs come from the same reporting period. Use them together to see whether profit, cash, and short-term obligations are telling the same story.

Bookkeeping, operations, and billing

Use the Accounts Receivable Calculator for turnover and DSO, the Accounts Payable Calculator for turnover and DPO, and the Inventory Turnover Calculator for stock efficiency. The Depreciation Calculator supports fixed-asset estimates.

For everyday workflow, the Invoice Generator creates print/PDF-ready invoices and the Expense Tracker totals and exports expenses for the current session. These lightweight utilities complement accounting software rather than trying to replace a full bookkeeping system.
