About the calculator library
How many calculators are there?
78 calculators in 5 topics: Taxes, Retirement, Investments & markets, Business and Household planning. Each has its own page explaining what it does, who asks, and what your firm receives.
Which plan includes which calculators?
Every plan includes the tax, retirement, investment, business and household calculators. Practitioner (free) runs up to 5 at once, Firm up to 50 and Network has no cap. The three HSA calculators are Network only. See pricing.
Can I try them before embedding?
Yes. Every calculator page runs the live calculator, and the free Practitioner plan lets you put five of them on your own site before paying for anything.
Do all calculators use 2026 figures?
Yes. Statutory figures come from one sourced table, listed on the 2026 figures page.
Can I change labels, defaults and colors?
Yes, per calculator: titles, field labels, defaults, help text, button text, colors, fonts and themes.
Do the calculators work in other languages?
Every calculator can show in English, Spanish, Simplified Chinese, Korean, Vietnamese or Arabic, and visitors can switch.
Can I put several calculators in one widget?
Yes. Widgets bundle calculators into a floating launcher, tabs, a button set or a card grid. See widgets.
Are calculator results advice?
No. They are estimates from the client's inputs. Each calculator states its limits and carries a disclaimer you can adapt.
No question matches that filter. Clear it to see them all, search the whole site, or ask us directly; we reply within one business day.
