How to write a financial plan in an afternoon: a step-by-step guide

Short answer: a financial plan is a short written document that says where you are, where you want to be, and what you will do each month to get there. You can write a solid first version in an afternoon by following eight steps: calculate your net worth, track your cash flow, set specific goals, build an emergency fund, handle debt, get the right insurance, invest for the long term, and schedule a yearly review. It does not need to be perfect, only written down and revisited.

Step 1: Find out where you stand

List what you own and what you owe, and subtract. That is your net worth. Then look at three months of bank and card statements to see what actually comes in and goes out each month. Most people are surprised, either by how much they spend on small things or by how much is left over.

Step 2: Set specific goals with numbers and dates

"Save more" is a wish. "Save $30,000 for a house deposit in four years" is a goal. For each goal, write the amount, the date and the monthly amount needed. Divide your goals into short term (under three years), medium (three to ten) and long term (retirement and beyond), because each should be invested differently. If you have a partner, set shared goals together; see how couples should manage money.

Step 3: Build a safety net

Start with a small starter fund, such as one month of essential spending, then work toward three to six months, or more if your income is uneven. Keep it in a safe, accessible account. The size is covered in how many months of emergency fund you need. Set aside separate money for predictable irregular costs with sinking funds.

Step 4: Deal with debt

List every debt with its balance, interest rate and minimum payment. Pay the minimum on all of them, then send extra money to the highest-rate debt first. Debt above roughly 7 to 8% is usually worth paying down before investing beyond an employer match, though it depends on your situation. See avalanche vs snowball, and for student loans, pay off early or invest.

Step 5: Get the right insurance

Insurance protects the plan from one bad event. Check health, disability, renters or home, auto, and, if anyone depends on your income, term life cover. Do not buy more than you need or less than you could not afford to lose. See term vs whole life and over or under insured.

Step 6: Invest for the long term

  1. Capture any employer match. It is part of your pay.
  2. Use tax-advantaged accounts such as a 401(k), IRA and, if eligible, an HSA. The order matters; see the tax-advantaged account order report and Roth vs traditional IRAs.
  3. Choose a simple mix. Decide your asset allocation and use low-cost funds; check expense ratios.
  4. Automate contributions so saving happens before spending.

Step 7: Check you are on track for retirement

Estimate how much you will need, then compare it with where your savings are heading. Our guides on how much you should have saved by age and your real retirement number help you set a target, and the retirement and FIRE readiness report tests it against bad market timing.

Step 8: Put it on one page and schedule a review

Write down: your net worth today, your goals with amounts and dates, your monthly savings by goal, your debt payoff order, your insurance, and your investment mix. Then book a yearly review in your calendar, plus a check whenever life changes: a new job, a move, a child, a marriage or a divorce. A plan you revisit once a year will outperform a perfect plan you never open.

A simple order of priorities

PriorityWhy it comes here
1. Starter emergency fundStops a surprise bill from becoming debt
2. Employer matchAn immediate, guaranteed return
3. High-interest debtPaying it off is a guaranteed return equal to the rate
4. Full emergency fundProtects everything else
5. Tax-advantaged investingLets growth compound with a tax benefit
6. Other goalsHome, education and so on, invested to match the timeline

If you would rather see all of this scored and ranked for your own numbers, the Annual Money Checkup rates your cash, debt, savings, retirement, protection and net worth, and the financial plan report builds the full plan for you.

General education, not financial advice. A plan should reflect your own goals, taxes and circumstances, and may be worth reviewing with a qualified professional.

Frequently asked questions

What should a financial plan include?

Your current net worth and cash flow, specific goals with amounts and dates, an emergency fund, a debt payoff plan, insurance, an investment approach, a retirement estimate, and a schedule to review it.

How do I start a financial plan?

Calculate your net worth and track three months of spending. Those two numbers show where you stand and what you have available to put toward goals.

In what order should I do things like saving, paying debt and investing?

A common order is a starter emergency fund, then your employer match, then high-interest debt, then a full emergency fund, then tax-advantaged investing and other goals. Your situation may call for changes.

How often should I update my financial plan?

Review it at least once a year, and whenever something big changes, such as a new job, a move, a marriage, a child or a major purchase.

Do I need a financial adviser to write a plan?

No. Many people write a sound first plan themselves. An adviser can help with complex situations such as business ownership, large estates or tax planning.
