Everyday Calculators
These are the simple, general-purpose money calculations that come up day to day. You get percentage calculations covering four patterns — discounts, increases and decreases, and ratios — a budget calculator that compares your income and expenses against the 50/30/20 rule with a pie chart, bill splitting that handles the remainder, a marketplace fee comparison across Mercari, Rakuma, Yahoo! Flea Market and Yahoo! Auctions, a resale profit tracker for tallying cost, revenue and profit across many items you are reselling, VAT conversion between gross and net with a table of rates by country, and offline validation of a VAT number’s format and check digit.
