The «Financial Calculator» site has been operating since 2008. Initially, it featured only loan, deposit, and lease calculators, but over time much more has been added — today it offers over 75 online tools: geometric shapes, unit converters, percentages, VAT, trigonometry, and dates. All calculations are free, require no registration, and include formulas and explanations on each calculator's page.
The loan and deposit calculators may have a slight margin of error due to the varying number of days in months — for the convenience of calculation, the average number of calendar days is used.
