How to start financial planning: the ultimate step-by-step guide
You've been meaning to sort out your finances for months, maybe years. You know it matters. But every time you sit down to start, you're not sure what 'starting' actually looks like. This guide fixes that.

The reason most people never create a financial plan isn't laziness; it's that nobody showed them the steps. You wouldn't build a house without blueprints, but somehow we're all expected to figure out decades of financial decisions by intuition alone. Below is a practical, step-by-step method for building your first financial plan.
It works whether you use Meet Warren, a spreadsheet, or pen and paper. We'll show you what each step looks like inside our platform, but the approach itself is universal.
(Disclaimer: Yes, we're a platform that helps you do this, but we believe that even if you don't use Meet Warren, everyone still deserves to know how to go about this.)
How our method differs from others
We start with the future, not the present. We start with long-term and work backwards. Broad first, detail second.
Our philosophy
Start general, get specific later. Get an initial plan done quickly then work from there. It's easier to edit a basic plan than try to make a super complicated one from scratch.
Step-by-step guide
Set up a questions box
30 secBefore you begin, grab a notepad or open a note on your device and label it "Financial Questions". As you work through the steps below, you'll have questions ("what ISA should I use?", "how much stamp duty would I pay?"). Park them here and move on. This stops you from disappearing down research rabbit holes before you've got the big picture down!
Start with your Goals
Define your long-term goals
4 minLong-term goals are the big-picture outcomes that will take 5+ years to achieve (e.g. buying a home, retiring comfortably, becoming debt-free). Don't overthink this. Just ask yourself: where do I want to be in 5, 10, 15 years? What life events am I planning for?
- List the big life events you see ahead (property, family, retirement)
- Identify your dream goal and your most pressing priority, which may not be the same thing
- Make each goal specific: use the SMART framework (Specific, Measurable, Achievable, Realistic, Time-bound)
- Think about opportunity cost: wanting to buy a property AND retire early likely means sacrificing one for the other
Add your short-term goals
5 minShort-term goals either feed into the long-term ones or run alongside them. Work backwards from your main goal: to get there, what needs to happen in the next 6–12 months?
Examples:
If long-term goal = buy house
Related short-term goal = improve credit score
Unrelated short-term goal = save for dream holiday next summer
- Build an emergency fund (3–6 months expenses)
- Pay off credit card debt
- Save for a house deposit
- Maximise ISA contributions
- Increase pension contributions
- Save for a wedding
- Build a career change fund
- Plan for parental leave
- Save for children's education
- Reach financial independence / early retirement
Gather your information
Now that you know where you're heading, you need to understand where you're starting from. This doesn't have to be exact; rough estimates are fine at this stage. Don't let perfection stop you from starting.
Gather your core financial information
5–10 minThese are the basic numbers that define your current financial position. You probably know most of them already; it's just a matter of writing them down in one place.
01 · Income
02 · Cashflow
03 · Assets & Savings
04 · Debts & Liabilities
Add goal-specific context
5–8 minBeyond the basics, your goals will need specific context. This falls into two categories:
Set your budget baseline
3 minBefore you start allocating towards goals, you need a realistic picture of your monthly cashflow. A simple starting framework:
The 50/30/20 rule:
- 50% of income → needs (rent, bills, food)
- 30% of income → wants (dining, hobbies, subscriptions)
- 20% of income → savings and debt repayment
This isn't a strict rule; it's just a starting point. Your actual split will depend on your goals and circumstances. The point is knowing roughly how much you have to work with each month.

Connect your goals to your numbers
Goal-based deep dive
With Warren: 0 min (go make a cup of tea) · Without Warren: 15 min per goalFor each goal, research the specific avenues available to you. If your goal is buying a house, that means understanding deposit requirements, mortgage rates, stamp duty thresholds, and LISA/Help to Buy schemes. If it's retirement, it means pension contribution limits, employer matching, and drawdown rules.
Just get enough clarity to put rough numbers against each goal.

Refine, compare, prioritise
You've got a rough plan. Now it's time to stress test it, answer your open questions, and turn it into something actionable.
Consult your question box
5–15 minGo back to the questions you parked earlier. Sort them into "need to answer before moving on" and "can wait." Tackle the urgent ones now. They might change your assumptions or goals. The rest become your ongoing learning list.
Think about the biggest 'what if' scenarios
5–10 minWhat are the biggest things that could change your plan? A job change (income up or down), interest rate movements, a relationship change, an unexpected expense. You don't need to model every possibility, just the 2 or 3 most likely or impactful scenarios.
Compare scenarios
10 minIf you can, model these scenarios side by side. What does your timeline look like if you save aggressively vs moderately? What happens if you buy a £400k property vs a £500k one? Seeing the comparison turns abstract worry into concrete trade-offs.

Break down your actions
Break each big action into 2–3 manageable sub-tasks: "save for a house deposit" becomes "open a Cash ISA, set up a £2,200 standing order, move existing savings across." Remember: concrete beats vague.

On Track
The model has a clear route because the existing deposit and LISA funding assumptions work together.

Now the real work begins: sticking to your plan
Now that you've got the plan building out of the way, the biggest pitfall is making sure you actually stick to it. Maintaining a plan is crucial: keeping it alive as your life, income, and the economy change around you. Here's the minimum to stay on track:
Commit 20 minutes a week
ongoingThat's all it takes. Occasionally you'll want to reserve a bit more time, of course.
Some weeks you'll spend that time on actions: setting up an account, moving savings, adjusting a standing order, or updating your plan so it stays current.
Other weeks it's education: working through the question box you've been building or reading up on a topic that affects your plan.
Stay on top of financial news that affects you
With Warren: 5 min · Without Warren: 20 minCheck to see if any financial news impacts your plan this week.
Create a short list of keywords based on your goals and tips. For example, "ISA allowance", "State Pension", "CGT" and "S&P 500". Then type these terms into your chosen news platform and limit your search criteria to "this week" in order to make your weekly news dives more efficient. Many platforms also let you set up automatic alerts for certain topics.
Warren actively monitors UK news coverage of events that impact your plan. It then sends you weekly briefings with article links, summaries, and a personal impact statement.
Do a monthly check-in
monthlyOnce a month, compare where you are against where your plan said you'd be. Are you ahead, behind, or on track? If something has changed (e.g. a pay rise, an unexpected expense, a shift in priorities), update the plan.
Remember: A plan that doesn't evolve with you becomes decoration.
