The Mortgage Calculator gives the monthly payment, total interest and a year-by-year amortization schedule, with property tax and insurance if you add them. Try a $400,000 loan at 5%. Over 25 years it comes to $2,338 a month and $301,508 in interest. Stretch it to 30 years and the payment drops to $2,147, but the interest climbs to $373,023. That trade-off is easy to miss when you only compare monthly payments.

The Compound Interest Calculator projects savings with regular monthly contributions and your choice of compounding frequency, and shows the balance year by year next to what you actually paid in. The gap between those two columns is the interest doing the work.

The Salary Calculator converts between hourly and annual pay and breaks it into daily, weekly, bi-weekly and monthly amounts, which helps when one offer is quoted per hour and the other per year.

Nothing you type is sent anywhere, and there’s no email gate. These are planning estimates, not financial advice: lenders compound and charge fees differently, so confirm final numbers with yours. For the concepts, start with how mortgage payments work.
