Advertising disclosure

MoneyMathHQ is free to use. When you follow a link to a partner offer, we may earn a commission from that company at no extra cost to you. These relationships help keep every calculator on the site free, with no signup or paywall.

Commissions never affect calculator results. Every number on this site is produced by standard, published financial formulas — the same ones lenders and finance textbooks use. Partner offers cannot change a rate, a payment, or any other output. You can reproduce every result by hand from the "How this is calculated" section on each page.

Any sponsored placement is clearly labeled with an "Advertiser disclosure" tag and rendered in a card that is visually distinct from calculator output. We only feature offers we consider directly relevant to the calculator on the page, and we limit each page to a single placement.
