Why these three
The numbers Wavro already works out
Each calculator uses the same rules Wavro runs on every shift: holiday builds up from approved timesheets, labour cost is checked against published bands for your trade, and bank holiday rates apply on the right dates. Read more on the blog, or see it running on a sample week.
