But It Will Replace the Old Planning Model
At a recent Academy of Life Planning Practice Management Circle, we explored a question that is increasingly appearing across the profession:
What happens to cashflow planning when artificial intelligence can model financial scenarios instantly?
As you might expect, the discussion sparked strong opinions — thoughtful, constructive, and rooted in decades of professional experience.
Several planners raised important challenges about the role of AI in financial planning.
Those concerns deserve serious consideration.
Rather than dismissing them, this article shares the three key challenges raised during the discussion — and how we are thinking about them as a profession.
Because something important is happening.
The Three Key Challenges Raised
During the Practice Management Circle discussion, three important concerns were raised about AI in financial planning:
1️⃣ Risk of incorrect assumptions
Financial modelling relies on accurate inputs. If individuals use AI tools without understanding assumptions such as inflation, tax rules, or retirement timing, projections could easily become misleading.
2️⃣ Robustness of professional software
Traditional planning tools have structured assumptions, version control, and tested modelling frameworks. AI systems are more conversational and flexible, which raises questions about consistency and reliability.
3️⃣ Behavioural reality — most people won’t do the work
Even when clients pay for advice, many struggle to gather financial data, estimate spending, or define goals. Expecting individuals to build their own financial models may be unrealistic for most households.
These challenges do not invalidate the role of AI in planning — but they highlight an important transition:
AI may make financial modelling more accessible, but professional judgement remains essential.
Challenge 1
“AI could lead clients into dangerous assumptions”
Experienced planners know that assumptions drive outcomes.
A small error in inflation, tax treatment, or retirement timing can dramatically change a long-term projection.
One participant raised an important point:
If individuals begin modelling their own finances using AI tools, they could easily follow incorrect assumptions or misunderstand projections.
This concern is legitimate.
Financial modelling has always required careful judgement.
Our response
Mistakes are not unique to AI.
Traditional financial planning models are also dependent on assumptions — and those assumptions are often wrong.
What AI introduces is something new:
iteration.
Instead of receiving a single projection produced once a year, individuals can explore multiple scenarios interactively.
More importantly, AI does not remove the need for professional judgement.
It changes the nature of the professional role.
Several of my own clients now describe the planner’s role as a “second brain” — someone who helps sense-check assumptions, interpret scenarios, and identify blind spots.
The modelling may become more accessible.
But the wisdom required to interpret it remains deeply human.
Challenge 2
“Professional planning software is more robust”
Another challenge raised was technical.
Traditional financial planning tools such as Voyant, Truth, and CashCalc have been engineered over many years with:
• structured assumptions
• version control
• regulatory frameworks
• tested modelling logic
By contrast, AI tools are fluid and conversational.
They generate responses dynamically.
That understandably raises questions about consistency and reliability.
Our response
This is an important observation.
AI alone is not a finished planning system.
But AI can become extremely powerful when used inside structured frameworks that guide assumptions and capture model logic.
In other words, the future may not be:
AI replacing financial planning software.
Instead it may be:
AI becoming the modelling engine within new planning environments.
That is precisely the direction we are exploring with the Total Wealth Plan framework.
The objective is not to eliminate structure.
It is to combine structure with the flexibility and accessibility AI provides.
Challenge 3
“Most clients will not do the work themselves”
Another point raised during the discussion was behavioural.
Even when people seek professional advice, they often struggle to:
• gather pension statements
• calculate spending
• estimate retirement costs
• define lifestyle goals
If clients already find these tasks difficult, how realistic is it to expect them to build their own financial models using AI?
Our response
In many cases, it is unrealistic.
Most people will not conduct detailed financial modelling themselves.
But something important is already happening.
Research shows that millions of people are now using AI tools for financial questions — particularly for budgeting, saving, and understanding pensions.
At the same time, surveys highlight a significant trust gap: people are willing to experiment with AI but still want validation from trusted professionals.
This is the key insight.
AI is becoming the first place people explore financial questions, but not the final authority.
That creates a new opportunity for planners.
Recent research from the Lloyds Banking Group Consumer Digital Index found that 56% of UK adults — around 28 million people — have used AI to help manage their money in the past year, making personal finance the most common use of AI in the UK. The most common activities include budgeting, savings planning, and financial education. At the same time, studies highlight a significant trust gap, with many users concerned about accuracy and data privacy when relying on AI tools for financial guidance.
The Real Shift
From dependency to agency
Historically, most financial planning tools were designed for advisers.
The planner controlled the model.
The client received the answer.
AI changes this dynamic.
Individuals can increasingly participate in exploring their own financial futures.
This does not eliminate the role of the professional.
But it does change the relationship.
Instead of acting primarily as the gatekeeper of information, planners increasingly become:
• guides
• interpreters
• capability builders
• trusted thinking partners
In other words:
AI may democratise financial modelling.
But wisdom still requires human judgement.
Why This Matters
Financial planning has never been just about spreadsheets.
It is about helping people navigate the most important decisions in their lives:
• retirement
• family priorities
• career transitions
• legacy intentions
• wellbeing and purpose
AI can assist with modelling numbers.
But it cannot replace empathy, experience, and wisdom.
The opportunity for planners is not to compete with AI.
It is to focus on the areas where human insight matters most.
A Constructive Debate
What I appreciated most about our Practice Management Circle discussion was the spirit in which the debate took place.
Experienced professionals raised important concerns.
We explored both risks and opportunities.
And we acknowledged that this technology is evolving rapidly.
This is exactly the kind of dialogue our profession needs.
The future of financial planning will not be determined solely by software vendors or technology companies.
It will be shaped by planners who are willing to question assumptions, experiment with new tools, and rethink how they create value for clients.
The Invitation
At the Academy of Life Planning, we believe the profession is entering a new phase.
One where planning becomes less about controlling information…
…and more about empowering people.
AI will undoubtedly reshape how financial modelling works.
But the real future of planning will still depend on something far older than technology:
human wisdom, trust, and judgement.
And those are qualities no algorithm can replace.
Join the Conversation
The future of financial planning will not be shaped by technology alone.
It will be shaped by planners who are willing to explore new ideas, challenge assumptions, and rethink how value is created for clients.
That is exactly what the Academy of Life Planning’s Practice Management Circle is designed to do.
Each week, experienced planners come together to discuss real challenges facing the profession — from AI and technology to client psychology, practice design, and the future role of the planner.
It is a space for open, thoughtful dialogue among professionals who care deeply about the evolution of financial planning.
If these questions interest you, we invite you to join us.
