Everything you need to accelerate your financial journey - from free downloadable resources to carefully selected tools and courses that can transform your wealth-building approach.
Planning your financial future doesn't require expensive software or complicated spreadsheets. I've tested dozens of online calculators, and these are the three tools I actually use in my own financial planning. They're free, straightforward, and genuinely helpful for UK savers and investors.
Best for: Understanding compound interest and tracking savings goals
This is the calculator I wish I'd found years ago when I first started saving. It's simple but powerful - you can see exactly how your money grows over time with different interest rates and monthly contributions.
What makes it useful:
Shows you the real impact of compound interest
Lets you experiment with different monthly savings amounts
Visualises how small changes in interest rates affect your long-term returns
Perfect for planning specific savings goals (like that car down payment or emergency fund)
How I use it: Before opening any savings account, I plug in the interest rate to see what my £200 monthly contributions would actually grow to over 24 months. The difference between a 2% and 4% AER is more significant than you'd think - this calculator makes it crystal clear.
Best for: Long-term investment planning and retirement projections
This one's more comprehensive and perfect for when you're ready to think beyond short-term savings. Financial Mentor offers multiple calculators on their site, but their retirement and investment tools are particularly solid.
What makes it useful:
Projects long-term investment growth with realistic return assumptions
Accounts for inflation (which most basic calculators ignore)
Helps you understand how much you need to invest monthly to reach big goals
Great for testing different investment scenarios
How I use it: I run my investment strategy through this calculator every quarter to check if I'm on track. It's especially helpful for understanding whether my current £250/month investments across multiple platforms will actually get me where I want to be in 10, 20, or 30 years.
Pro tip: Be realistic with your return assumptions. I use 6-7% for long-term stock market projections rather than overly optimistic 10%+ figures you sometimes see online.
Best for: Creating your own structured 24-month savings strategy
I documented my entire approach to saving £4,800 over 24 months for my car finance situation. This isn't just theory - it's the actual plan I'm following, complete with:
Monthly breakdown: How I calculated my £200 target
Expense reduction strategies: The specific areas where I found savings in my budget
UK-focused tips: Council tax, energy bills, transport costs - all tailored to British household expenses
Account selection criteria: How I chose the correct high-interest savings account
Tracking methods: The exact tools I use to monitor progress
Motivation techniques: How I stay on track when it gets tough
Download the Complete UK Savings Plan Guide
This is the comprehensive guide I created after making that £17,000 car finance mistake. It includes research on average UK household spending, comparison tables for expense categories, and the real-world adjustments I made to my own budget.
What you'll find inside:
Monthly savings target calculator
Household expense reduction checklist (UK-specific)
Comparison of UK savings account types (Easy Access, Fixed Rate, Notice Accounts)
Tips for staying motivated over 24 months
Emergency fund building strategies
Real examples with actual numbers (not just vague advice)
📊 Portfolio Analysis Tools
Once you’ve got your savings plan sorted, these free tools help you understand how a mix of investments might behave over time.
4. Portfolio Visualizer
Best for: Seeing how different investment mixes have performed in the past, and what the future range of outcomes could look like
This is a free, professional-grade tool used by investors around the world. You don’t even need to sign up: just open it and start testing ideas.
What makes it useful:
Backtest Asset Class Allocation: test a simple mix, such as 80% global shares and 20% bonds, and see how it would have done through past crashes and recoveries
Monte Carlo Simulation: see the best, worst and typical outcomes for a long-term plan, not just one optimistic number
Free for personal use: up to 15 assets, no account needed
Things to know before you start:
The site is US-based, so results are often shown in dollars, and many funds are American. For UK investors, the asset-class tools work best (for example, “Global Stocks” rather than a specific UK ETF).
Everything is based on past performance, which doesn’t guarantee future results. Treat it as a learning tool, not a crystal ball.
5. Finominal Portfolio Analyser
Best for: UK investors who want to analyse their own ETF portfolio in pounds
Where Portfolio Visualizer is US-focused, Finominal is a London-based tool that understands UK-listed ETFs and shows results in pounds. Add your funds and their weights, and it compares your portfolio with a global benchmark.
What makes it useful:
Works with London Stock Exchange ETFs (choose the . LSE version of each ticker)
Shows growth, worst falls, fees and dividend yield against a benchmark
Free plan includes almost all tools, and one saved portfolio
Things to know before you start:
You’ll need a free account to use it
It’s built for professionals, so start with the Overview tab and ignore the advanced tabs at first
Results are based on past performance and don’t predict the future
Here's my recommended approach:
Start with the Savings Plan Guide - Understand the full framework and calculate your own monthly savings target based on your goal
Use the Vertex42 Calculator - Input your monthly savings amount and different interest rates to see which savings account will get you to your goal fastest
Check Financial Mentor for long-term planning - Once you've conquered your first savings goal, use this to plan your next steps (investments, retirement, etc.)
The Vertex42, Financial Mentor and Portfolio Visualizer tools are free, and I’m not affiliated with any of them.
The biggest mistake I made in my early twenties was not having a clear plan or understanding how my money could grow. These calculators won't magically create wealth, but they'll show you exactly what's possible with consistent saving and realistic planning.
