Savings Interest Calculator was created by Cedrick Reese, a retired veteran and web developer who enjoys building free, user-friendly online tools that simplify everyday tasks. His journey began in the early 2000s with affiliate marketing and niche site development, which grew into a passion for creating practical digital utilities and calculators. After retiring, he earned a Computer Systems Technician certificate from UEI College, completed Electro-Mechanical Technologies at Tulsa Welding School, and finished the Carpentry program at Florida State College at Jacksonville.

How These Calculators Are Built
Every formula on this site is checked against multiple independent sources before it goes live, then cross-verified against real calculations, not just written once and trusted. Every calculator runs entirely in your browser -- nothing you type is sent to a server. This site uses privacy-respecting analytics (Umami) to see how many people visit and which pages are useful; it doesn't use cookies, doesn't collect personal data, and doesn't run ads or affiliate tracking of any kind.
