Percentages describe your plan; they are not grades. The useful question is whether the margin is deliberate and durable.

Method, assumptions, practical next steps, and limits.
Build a plan around the money you actually receive
A useful spending plan starts with take-home pay, not salary. Add the four broad groups below and the builder shows whether the plan has margin or asks more of the month than the month can provide.
How the result is calculated
Monthly margin = take-home income − essentials − goals − debt − flexible spending
The category percentages use take-home income as the denominator. They are diagnostic, not rules. Housing costs, care obligations and income volatility make one universal ratio unrealistic.
What to do next
If the result is negative, start with flexible spending, then inspect large fixed costs and the timing of debt or savings goals. If it is positive, assign the margin deliberately instead of letting it disappear.
