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 we won't do
- We won't recommend a product or service purely because it pays a higher commission.
- We won't use screening rules (like the "1% rule") that we think set unrealistic expectations, regardless of whether a rule like that would drive more clicks.
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.
