Use of the calculators

CalcPrime calculators are provided free of charge for general information and educational purposes. You may use them for personal and business purposes.

No professional advice

Results are estimates based on the inputs you provide and standard formulas. They are not financial, tax, legal, medical or engineering advice. Tax rules, interest rates and health guidance change and depend on your circumstances — always confirm important decisions with a qualified professional.

Accuracy

We work hard to keep formulas and tax tables accurate, but we do not guarantee that results are free from errors and accept no liability for decisions made using them.
