Most personal finance websites make money when you click a lender, apply for a card, or sign up for a service. That's not a conflict of interest they disclose, it's the business model. The content, the rankings, and the "best of" lists are shaped by it.
Wallet Sprouts doesn't have affiliate deals, sponsored placements, or referral fees. The calculators produce a number based on what you enter. That's the only output. There's no nudge at the end pointing you toward a partner lender, because there aren't any partner lenders.
This site is small by design. Small means no investors to answer to, no ad targets to hit, and no pressure to monetize your attention. It also means the tools can stay focused on doing one thing well: giving you an accurate, honest answer.
