Goal budgeting: from target to monthly plan
Translate a long-term goal into a number you can hit this month — and a system that tells you whether you're still on track.

Define the goal in one sentence
"A 20% downpayment on a 1.4M property in 36 months" is a goal. "Buy a house someday" isn't. The math only works once the amount, the timeline, and the milestone are all in writing. Vague goals produce vague budgets.
Divide, then add expected return
Goal amount divided by months gives the naive contribution. If the money will sit in an investment or savings vehicle that earns a return, fold that in — it usually shaves ten to fifteen percent off the monthly number on a multi-year goal. Don't be optimistic about the rate.
Make it a line on the budget, not a wish
The monthly contribution goes on the budget like rent. Same priority, same automation. If the budget can't carry it, the goal is too aggressive, the timeline is too short, or the lifestyle needs a trim. Better to find out in month one than month twenty.
Check progress against schedule, not vibes
Every quarter, compare what you've actually contributed to what the plan said you'd contribute by now. If you're behind, decide once: extend the timeline, increase the rate, or shrink the goal. Quietly drifting is the only failure mode that matters.
