About Everyday

Who operates this website?

Everyday is operated by GEOINNOVATION CO., LTD. It is an independent, English-language calculator website for people planning everyday decisions in the United States. We default to US dollars and US customary measurements. This product is separate from the Korean website onpeople.kr.

What we aim to make useful

A monthly payment alone rarely tells the whole story. Our tools let you adjust rates, timing, fees, household costs and other assumptions, then inspect the result and its calculation method. Categories cover taxes, pay, saving, borrowing, retirement, housing, health, transport and practical household questions.

The library includes baseline calculations, target-value solvers, sensitivity tables and scenario comparisons. Related tools may share an underlying formula. We do not claim that 500 tools represent 500 unrelated mathematical methods.

Limits you should know

We are not a government agency, lender, tax preparer, medical provider or investment adviser. Default inputs are examples, not live market data or personalized recommendations. Tax models cover only the years, filing situations and states identified on each page. Verify decisions with the relevant agency or qualified professional.

Accountability

Each calculator explains its assumptions, and major topics include worked examples and frequently asked questions. Read our methodology and corrections policy. For an error or question, write to hoons9096@gmail.com.
