Advertising & Affiliate Disclosure

SFRCalc's calculators are free to use and always will be. This page explains how the site is funded, so it's clear where that money comes from and how it does or doesn't shape what you read here.

Advertising

Some pages on this site may display advertising served by third-party ad networks (such as Google AdSense). These networks may use cookies or similar technology to show relevant ads. We don't control which specific ads appear, and displaying an ad isn't an endorsement of the advertiser.

Affiliate links

Some links on this site — for example, to lenders, insurance providers, or software tools mentioned in an article or calculator — may be affiliate links. If you click one and sign up for or purchase something, we may earn a commission or referral fee. This comes at no additional cost to you.

What this doesn't change: Affiliate relationships don't affect our editorial judgment, our calculator math, or the guidance in our articles. We don't accept payment to recommend a specific product, and we don't adjust a calculator's formulas to favor any partner. If we wouldn't recommend something to a friend, we don't link to it here for a fee.

What we won't do

If you have questions about a specific link or ad on this site, or think something here is misleading, we want to hear about it.
