About this allocation tool
This calculator splits a single total by percentages. It is ideal for budgets, savings plans, team time splits, or any case where you want to allocate a pot across categories. Add rows, name each slice, set the percentages and the amounts update straight away. A running check shows the combined percentage so you can aim for 100 and avoid gaps or overlaps. The layout is kept simple so you can move quickly and focus on the plan.
A good pattern is to start with the non-negotiables, set their percentages, then fill the rest to 100. You can copy the amounts into a sheet or notes once you are happy. If your total is not money, it still works fine. Use hours, units or any other quantity. The calculator does not round the percentages for you, so feel free to use decimals when you need more control. Stable Numbers keeps tools like this stripped back and fast so you can make changes on the fly without losing your place.
