BLTHZRD

Balthazard's formula, worked out for you. Several impairments do not add up. Each one applies to what the ones before it left whole, so two rates of 25.5% and 12% combine to 34.44%, not 37.5%. The total climbs toward 100% and never passes it. Add as many rates as you need. Set each one on a wheel — no keyboard, no decimal separator to get wrong, nothing outside 0 to 100 to type by mistake. The combined rate updates as you go, and you can open the working to see the running total after each rate. Free, with no accounts, no adverts and no data collection. It does one calculation and does it properly. Available in English, Turkish, German, French, Spanish and Italian.
