Savings and investments checklist

15 questions on saving for 5–10 years and beyond. The framework favours broad index funds, low costs and infrequent trading.

Base: cash flow

00 / 05
Do you know your monthly fixed costs?Rent, insurance, phone, subscriptions.
Do you have an emergency reserve, quick to reach and kept apart from other savings?
How much of your take-home pay do you set aside each month (saving + investing)?
Consumer debt: buy now pay later, overdraft, a credit card balance?Mortgages and low-rate loans don’t count here.
Is money you’ll need within 3 years sitting in stocks?A down payment, a car, tuition.

Structure: the portfolio

00 / 06
Money beyond the reserve and the next 3 years’ needs is…
What does your brokerage portfolio cost a year: fund costs (TER) plus account fees?Weighted by amount; account fees as a % of the whole portfolio.
What share sits in broad core index funds?A core fund holds hundreds or thousands of companies across many countries, or a whole market.
How many different indices do you hold?Count indices, not funds.
What share is in individual stocks, including employer shares and RSUs?
Leveraged products: CFDs, options, knock-outs, leveraged ETFs?

Behaviour: habits

00 / 04
How often do you check your portfolio?
In the last 6 months, how many positions did you sell within 3 months of buying?Rebalancing sales don’t count.
In the last 12 months, did you buy something because of a social media post: a video, a tip, a tweet?
If your portfolio fell 30% next month, you would…

Approach and scoring criteria

The checklist reviews your budget, portfolio and habits against the principles of long-term index investing. Green means your answers meet these criteria. It does not guarantee returns or show whether your savings will cover your goals.

Why this approach?

The check follows the Bogleheads philosophy: invest regularly, diversify broadly, keep costs low and follow a plan. This reduces dependence on individual companies, fees and the temptation to predict market moves. Index funds can fall too; the appropriate stock allocation depends on your horizon, goal and tolerance for losses.

Three blocks

Base covers expenses, the reserve, regular saving and debt. Structure covers costs and the allocation of investments. Behaviour covers trades and reactions to market drops. The reserve and money for near-term goals are considered separately from long-term investments.

How the result is scored

  • Answers appear shuffled and without colour. Colours appear once every active question is answered. Colours already shown stay visible when answers change.
  • For costs and the core share, “don’t know” counts as a red answer.
  • A block is red if any line is red; green if none is red and at least 60% are green (3 of 5, 4 of 6, 3 of 4); otherwise yellow.
  • The result is red at 2 or more red answers; green if all rated blocks are green; otherwise yellow. If only Base is rated, its colour determines the result.
  • In question 6, “all in savings accounts and deposits” and “nothing beyond the reserve yet” switch questions 7–15 off. The first answer is red; the second is not rated.

Where the thresholds come from

Geldchen chose the thresholds of 10%, 0.25%, 60%, 3 years and 30% for this check. The sources explain the principles but do not validate each threshold. For example, the 50/30/20 rule allocates 20% of take-home pay to saving and debt repayment. Here, saving 10% regularly is enough for a green answer.

What each question explains

  1. Fixed costs. Knowing your regular expenses helps size the reserve and see how much you can save. More
  2. Reserve. A reserve helps cover unexpected expenses without borrowing or selling investments during a downturn. More
  3. Savings rate. An automatic transfer after payday makes saving regular and reduces reliance on what is left at month-end. More
  4. Consumer debt. Debt interest is a contractual cost. Investment returns are uncertain; repaying debt reduces future interest payments. More
  5. 3-year money. Stocks can take years to recover from a drop. A near-term goal may force a sale at a loss. More
  6. Money beyond the reserve. If interest after tax is below inflation, savings lose purchasing power. That matters more over a long horizon. More
  7. Running costs. Fees reduce returns every year. Over a long horizon, they also reduce the amount left to compound. More
  8. Core share. Broad index funds reduce dependence on individual companies. They still carry the risk of the market falling. More
  9. Number of indices. Different indices can hold the same companies. Their number alone says little about diversification; this check favours simplicity. More
  10. Single stocks. A large single-stock share makes the result depend on fewer companies. With employer shares, your income depends on the same company too. More
  11. Leverage. Leverage magnifies gains and losses. ESMA found that 74–89% of retail CFD accounts lost money (2018). More
  12. Checking. Frequent checking makes short-term losses more noticeable and can distract from a long-term plan (Benartzi & Thaler, 1995). More
  13. Short holds. In a US study covering 1991–1996, the most active traders earned 11.4% a year versus the market’s 17.9% (Barber & Odean, 2000). More
  14. Tips. A popular post is no substitute for checking the risks. ESMA warns about unreliable investment information on social media (2021). More
  15. In a drop. In the US, fund investors earned 1.2 percentage points a year less than their funds over 2016–2025. The gap reflects cash-flow timing (Morningstar, 2026). More
Examples of a green result

Regular saving

A family knows its fixed costs and keeps 4 months of spending in a separate account. It saves 12% automatically after payday. The core holds 1–2 broad index funds costing about 0.2% a year. Individual stocks account for under 15%; there is no leverage. The family checks the portfolio quarterly and follows its plan.

Starting again after a move

A family spends the first year after moving building its reserve, then starts investing 10% regularly in a broad index fund. Small amounts alone do not prevent a green result: the check rates how savings are organised and the habits around them.

These are illustrative examples. All else equal, saving 10% and 40% regularly gets the same colour. The check does not assess whether savings are enough for early retirement (FIRE).

Questions and answers

This is not legal or financial advice.

Is this checklist investment advice?

No. This is an educational check using selected criteria. It does not choose products or account for your full situation. A personal plan may need calculations for specific goals or independent advice.

Why does “don’t know” count as red?

Without these numbers, it is hard to assess costs and allocation. Find TER in the fund documents and account fees in the broker’s price list. You can calculate the broad index fund share from the amounts invested.

Why is money in a savings account a red line?

The check favours long-term investing, so it marks the absence of market investments red. If interest after tax is below inflation, savings lose purchasing power. For the reserve and near-term goals, access and preserving the amount matter. Red here is a reason to review the horizon and goal.

Does saving more give a better result?

No. Saving 10% and 45% regularly right after payday gives the same green answer. Whether that amount covers your goal needs a separate calculation of time and contributions.

Why do two red lines make the whole result red?

That is the scoring rule: two red answers give a red result, and each question has equal weight. It flags several departures from the criteria, rather than calculating the probability of loss. If only Base is rated, one red answer is enough.

Do you store my answers?

No. The calculation runs in your browser; answers are written after the # in the address. That part is not sent to the server. The result link contains your answers: anyone you send it to can see them.
