Pay yourself a steady wage when your income goes up and down

Help me pay myself a steady amount each month.

My last 12 months: [takings and business costs per month]
What I need at home each month: [amount]
What the business must keep: [tax pot, a buffer for bills]
Current savings or buffer: [amount]

First ask me up to 4 short questions. Wait for my answers.

Then:
1. A steady monthly pay figure based on my figures, with the sum shown.
2. A buffer target, and how many months it would take to build.
3. A monthly routine: takings in, tax pot, buffer, pay, in that order.
4. Rules for a great month and a terrible month.
5. A Google Sheets layout to track the buffer.

Planning help only, not financial advice. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or figures. UK English.
