Who's Behind Math of Money

Math of Money is an independent site built and run by S M Ariful Islam Shawon, who writes the calculators and the explanations that go with them. It isn't owned by a bank, lender, or financial-product company, and it doesn't sell financial products. You can reach the author directly atcontact@mathofmoney.com or on LinkedIn.

How We're Funded

Math of Money is funded by advertising. We partner with reputable advertisers to keep our calculators free for everyone. Important: advertisements never influence our calculator results, methodology, or accuracy. Our calculators use only official sources and standard financial formulas.
