The calculators and articles on Vault Calculator are provided for general information and educational purposes only.
Not financial advice
Nothing on this website is financial, investment, tax, legal or accounting advice. We are not a bank, lender, financial adviser or licensed professional, and using our website does not create any professional relationship between you and us. Before you make a decision about a loan, mortgage, investment, debt or retirement plan, talk to a qualified professional who knows your situation.
Results are estimates
Our calculators use standard formulas and the numbers you enter. The results are estimates, not offers, quotes or guarantees. The real figures from your lender, bank or provider may be different because of factors our calculators do not include, such as fees, taxes, insurance, changing interest rates, rounding, or the exact way a lender calculates interest.
Assumptions and examples
Many calculators assume fixed interest rates, regular monthly payments and payments made at the end of each month. Investment and retirement calculators use the rate of return that you enter. Real returns change over time and are never guaranteed. The examples in our articles are for illustration only and do not predict what will happen to you.
Accuracy
We do our best to keep the calculators and content accurate and up to date, but we cannot promise that everything is free of errors or omissions. If you notice a mistake, please tell us through our Contact page.
Advertising
Our website shows advertising, including ads served by Google AdSense, which helps us keep the calculators free. We may earn money when ads are viewed or clicked. Advertisements are not recommendations from us, and we do not guarantee any product or service that appears in an ad.
Affiliate links
Some links on this website are affiliate links. If you click one and buy a product or service, we may earn a commission at no extra cost to you. We only link to services we think may be useful, and affiliate relationships do not change the results of our calculators or tools.
Use at your own risk
You are responsible for your own financial decisions. We are not responsible for any loss or damage that results from using or relying on the information on this website. For more details, see our Terms of Use.
