Nuvoro Studio is a small independent studio that builds free, simple tools and printables. Our calculators answer everyday money questions (how much a mortgage really costs, how long a credit card takes to pay off, how much an hourly wage is per year) without sign-ups, pop-ups or selling your data.
How we build the calculators
Every calculator uses standard, published formulas: the amortization formula used by lenders, compound interest with the compounding frequency you choose, and the snowball and avalanche methods for debt. Each page explains the formula and its assumptions in plain English so you can check the math yourself.
We test the math against known results before publishing and avoid figures that change every year, such as tax brackets, unless the page says where to find the current number.
Your data
Numbers you type are calculated in your browser and never sent to us. See the privacy policy.
Not financial advice
Our tools are for education and planning. For decisions with big consequences, check the numbers with official disclosures or a qualified professional.
