What Makes a Good DIY Financial Planning Tool
Before we dive into the specific tools, let me share what I look for in a DIY financial planning tool:
- Clarity of information: Can you actually understand your financial position at a glance?
- Actionable insights: Does it tell you what to do next, not just where you are?
- UK-specific features: ISA allowances, pension rules, and UK tax implications matter.
- Goal tracking: Can you set financial goals and monitor progress?
- Integration with UK accounts: Does it connect to UK banks and investment platforms?
- Education without jargon: Does it help you learn without overwhelming you?
Delphina
“Know where you are. Change where you’re going.”
Best for: Comprehensive Financial Clarity and Action Planning
Delphina stands apart because it does not just show you numbers. It helps you understand what those numbers mean for your future and, crucially, what actions you should take next. The platform connects with your UK accounts and investments to give you a complete picture of your financial position. But it goes further than most tools by helping you model different scenarios and understand the impact of different financial decisions on your future self. The tagline says it all: “Know where you are. Change where you’re going.” For UK investors who want more than retrospective data and genuine forward-looking guidance, Delphina is the tool I recommend first.
YNAB
Best for: Zero-Based Budgeting Enthusiasts
YNAB (You Need A Budget) has built a devoted following with its zero-based budgeting approach. Every pound has a job, and you assign your income to specific categories until you have accounted for everything. It is particularly effective for those who want to get intentional about their spending and build savings habits. YNAB connects with UK banks and helps you plan for irregular income, which many UK workers appreciate. The learning curve is steeper than some other tools, but users who commit to the method often describe it as life-changing.
Nutmeg
Best for: Hands-Off Robo-Advisory with Human Support
Nutmeg is one of the UK’s leading robo-advisors, offering managed investment portfolios with varying risk levels. If you want someone to manage your investments but at a fraction of the cost of traditional financial advisors, Nutmeg bridges that gap well. You answer some questions about your goals and risk tolerance, and Nutmeg builds and manages a diversified portfolio for you. They also offer fully managed ISA and pension accounts, handling the UK tax wrappers for you. It is a solid choice for investors who prefer a more hands-off approach while still wanting control over their general investment strategy.
Moneybox
Best for: Beginner Investors Saving Regularly
Moneybox has made a name for itself by making investing feel accessible and even fun. With features like round-ups that turn your everyday purchases into investments, it lowers the barrier to entry for those new to investing. The app connects with your bank account and rounds up spare change from purchases to invest automatically. Moneybox also offers Lifetime ISAs, Stocks and Shares ISAs, and pension products, all designed with UK savers in mind. It is particularly good for younger investors or those who want to start small and build up a habit of regular investing without feeling the pinch.
Emma
Best for: Financial Aggregation and Spending Insights
Emma takes a different approach by focusing on bringing all your financial accounts into one place. It connects with over 60 UK banks and financial institutions to give you a unified view of your finances. The app analyses your spending patterns, identifies subscriptions you might have forgotten about, and highlights areas where you could save. Emma is particularly useful for those who want to understand their cash flow without changing how they budget. It surfaces insights that might otherwise require manual work to discover, making it a valuable complementary tool to more active planning approaches.
Prospective vs Retrospective: Which Approach Suits You?
Most financial tools fall into one of two categories. Retrospective tools show you what has happened with your money. They aggregate your transactions, categorise your spending, and tell you where your money went. These tools are valuable for understanding habits and identifying areas for improvement.
Prospective tools, on the other hand, help you understand what might happen if you continue on your current path or if you make different choices. They model the future based on your current behaviour and potential changes.
Delphina is a prospective tool. It empowers you with clarity about where you stand today and helps you see how different financial decisions might affect your future. More than that, it gives you specific actions to consider. Most other tools on this list help you understand your past. Delphina helps you shape your future.
Understanding Delphina’s Limitations
No tool is complete, and it is important to be clear about what Delphina does and does not do. Delphina provides guidance, not execution. It helps you understand your financial position, model different scenarios, and identify actions you might want to take. But it does not execute trades, automatically rebalance your portfolio, or make investment decisions on your behalf. Think of it as a sophisticated compass that shows you where you are and which direction to travel, but you still have to take the steps yourself. For execution of investment decisions, you will still need a brokerage account or platform. Delphina helps you know what to do; you still need to do it.
