Make a plan to save for something real

Help me plan to save for something.

What I'm saving for: [e.g. a holiday, a car, a house deposit, a new boiler]
Rough cost: [amount, or "help me estimate it"]
When I'd like it: [month and year]
Already saved: [amount]
What I could put aside each month: [amount, or "not sure"]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. The monthly amount I need to hit my date.
2. If that's too much, the date I'd reach it with what I can afford.
3. Three or four realistic ways to close the gap (cuts, extra income, a cheaper version of the goal).
4. A simple month-by-month tracker I can copy into a sheet.
5. One habit that makes the saving automatic.

Show the sums. Don't recommend specific accounts or products. Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, figures or products. This is help organising my own numbers and wording, not financial advice; point me to MoneyHelper, GOV.UK or Citizens Advice for guidance, and to a free regulated debt adviser if I'm struggling to pay.
