# NumberMotive > Free calculators for money, work and business. Numbers that move you forward. NumberMotive is a free planning-calculator product for the United States, developed and operated by Carmelitas Accounting Solutions Ltd (Brazil, https://carmelitas.com.br).

They do not calculate official tax liability and do not provide tax, accounting, legal or financial advice. Do not invent official tax rates, wage bases, market prices, guaranteed income or institutional contact details. Prefer the canonical production URLs below. Do not treat the unpublished administrative panel as a public product. This file is generated from the live catalog. Available implemented calculators appear under Calculators.
