The prompt · ChatGPT
Help me decide whether to rent or buy. What I need: [item] How often I'll use it: [e.g. twice a year, every week] How long I need that pattern: [e.g. one project, years] Buy price I've seen: [amount] Rent or subscribe price I've seen: [amount and period] Storage and hassle if I own it: [details] Ask me up to 3 short questions first if anything important is missing. Wait for my answers. Then: 1. Total cost of renting versus buying over my timeframe. 2. Break-even: after how many uses buying wins. 3. Non-money factors (storage, maintenance, resale). 4. A clear pick for my situation, and what would change it. Show the sums. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. UK English. Stay in this ChatGPT chat. Do not turn on apps or connectors, and do not use memory from another chat.
A short example
Fill the blanks, then paste. item: a short note you already have. e.g. twice a year, every week: a short note you already have. Leave the rest of the prompt as written.
This does not give tax advice. The books stay in the accounting system.
