How to Write Your First Investment Plan on Paper
Key takeaways
- An investment plan is a simple document you follow instead of your emotions.
- It should include your goal, horizon, monthly amount, portfolio allocation, and firm rules.
- Pre-written behaviour for downturns protects you from panic selling.
- Write the plan simply — it fits on one page, and above all stick to it.
- Revisit it once a year, not every time the market moves.
Most bad investment decisions do not stem from ignorance but from emotions at the wrong moment. The remedy is boring and powerful: an investment plan on paper, written in calm, that you then follow when markets get hot. It fits on one page.
Why write a plan
When the market drops 30% and every headline screams "crash", your brain will shout "sell!". A pre-written plan is the voice of reason you trusted more in a calm moment than you will trust future panic. It is a contract with yourself — and keeping it is what makes an investor a winner.
Six points every plan needs
- Goal — why you are investing (income in retirement, a home, financial freedom) and how much you want.
- Horizon — how long until you need the money. The further out, the more equities you can handle.
- Amount — how much you will send each month and when (ideally automatically after your paycheck).
- Allocation — what you invest in and in what proportion (e.g. one broad ETF as the core).
- Rules — when you rebalance, whether you buy more during dips, what you will not touch.
- Behaviour in a crisis — pre-written: "when the market falls, I DO NOT SELL and I continue contributions".
An example of one plan sentence
"I invest 5,000 CZK per month by standing order into a broad equity ETF with a 20+ year horizon for retirement income. Once a year in January I review and rebalance if needed. During declines I do not sell and continue contributions. I will not touch the money for at least 10 years." That is enough — specific, clear, unambiguous.
Revise, but with restraint
The plan is not set in stone, but do not change it based on market mood. One annual review is enough — check whether goals, income, and allocation still fit, then carry on. Changing due to a life event (marriage, child, new income) is fine; changing because of a newspaper headline is not. How your plan would grow can be tested in the growth projection.
FAQ
What should an investment plan contain?
A goal, a time horizon, a monthly amount, portfolio allocation, rules (rebalancing, buying dips), and above all pre-written behaviour for a market downturn. It fits on one page and serves as a contract with yourself.
Why is a written plan so important?
Because it protects you from emotions at the wrong moment. When the market falls and every headline screams crash, a pre-written rule "I do not sell and I continue" is the voice of reason you trusted when calm — and keeping it decides the outcome.
How often should I change the plan?
Revise it roughly once a year or after a major life change (child, new income). Do not change it based on market mood or news headlines — the stability of the plan is its main value.
Does the plan have to be complex?
On the contrary, the simpler the better. One sentence with an amount, a fund, a horizon, and a rule for downturns is fine. What matters is not having a perfect plan but having a clear plan and actually sticking to it.
