Frequently Asked Questions

Is Smart Solver Online completely free?

Yes — all 16 calculators are free to use with no subscription, registration, or hidden fees. The site is supported by advertising. Please consider disabling your ad blocker on our site to help us keep it free.

Do you store my calculation inputs?

No. All calculations run entirely within your web browser. The values you type into any calculator are never sent to our servers. The only data we store locally is your theme preference (in your browser's localStorage).

Can I embed Smart Solver calculators on my website?

Currently we do not offer an embed API. If you're interested in a partnership or licensing arrangement, please contact us at info@smartsolver.online.

The result from your calculator doesn't match my bank / lender / employer. Why?

Our calculators use standard mathematical formulas and are designed for estimation purposes. Real-world results vary based on factors such as your credit score, specific lender terms, local tax laws, insurance, and fees that our calculators do not model. Always verify important figures with the relevant institution. See our Disclaimer for more information.
