Frequently asked questions
Are these calculators really free?
Yes. Every tool is free and requires no account, email address or payment. The site is supported by unobtrusive advertising and affiliate partnerships.
How accurate is the monthly payment figure?
The maths uses the standard amortisation formula, which is what lenders use to build repayment schedules. The figure is accurate for the numbers you enter. Your lender may add insurance, arrangement or late fees that change the real amount.
Do you give financial advice?
No. These are calculation and education tools. They show you the arithmetic and explain how financial products work so you can make informed decisions. They do not recommend products and are not a substitute for advice from a qualified professional.
Do you save or share what I type in?
No. All calculations run locally in your browser. Your figures are never transmitted to our servers or shared with anyone.
