Use CalculatorAccountants, bookkeepers, and financial controllers manage the financial records that drive business decisions.

Why Use Our Accounting & Bookkeeping Calculators
Accounting calculations follow specific standards (GAAP, IFRS, tax codes) that general business calculators cannot address. Depreciation methods affect net income and tax liability differently. AR aging determines bad debt allowances. AP days impact cash flow and vendor relationships. Payroll reconciliation ensures compliance with tax withholding and reporting. Our calculators apply professional accounting standards.

Frequently Asked Questions
What is the difference between book and tax depreciation?
Book depreciation (financial statements) often uses straight-line over useful life. Tax depreciation (IRS) uses MACRS with accelerated methods and specific class lives. Our calculator provides both methods and shows the deferred tax implications of differences.
How do you calculate allowance for doubtful accounts?
Methods include: percentage of sales (historical bad debt %), percentage of receivables (aging method with different rates per bucket), and specific identification. Our AR Aging Calculator applies the aging method with customizable rates per period.
