Frequently asked questions

Are these financial calculators free to use?+

Yes. Every calculator on the Netquity tools hub is free to use and does not require an account to start modeling scenarios.

Which free calculator should I use first?+

If you are focused on wealth growth, start with the compound interest or investment growth calculator. If you are trying to improve cash flow, the loan payoff, debt-to-income, and emergency fund calculators are usually the most useful first steps.

Can I use these calculators for real financial decisions?+
