Nuvoro Studio is a small independent studio that makes free everyday tools and printables: financial calculators (mortgage, loans, debt payoff, savings, salary), printable word searches, sudoku and mazes, all with answer keys.
How we build them
Calculators use standard, published formulas and explain them on the page so you can check the math. Puzzles are generated with full answer keys and checked before they go live. Read more about how the calculators are built.
Your data
Numbers you type are calculated in your browser and never sent to us. No sign-up is needed. See our privacy policy.
How the site is funded
Everything here is free. The site is supported by printable products and spreadsheets in our shop and, in the future, by ads.
Not advice
Our tools are for education and planning, not financial, tax or legal advice.
