MFA Investment Growth Calculator — Lifelong Access
£25 · One-time payment · No subscription · No expiry
What is it?
The MFA Investment Growth Calculator is an interactive, browser-based financial planning tool built specifically for NHS professionals who want to understand how their investments will grow — and how much fees and inflation are silently costing them along the way.
No spreadsheets. No jargon. Just clear, visual answers to the questions that matter most to your financial future.
What can you adjust?
Every variable that affects your real-world returns is fully adjustable:
Input | What it controls |
|---|---|
Initial Investment (£) | Your starting lump sum — whether that is £500 or £50,000 |
Monthly Contribution (£) | How much you add each month going forward |
Annual Growth Rate (%) | The compound annual growth rate quoted by your fund |
Investment Period (Years) | How many years you plan to stay invested |
Low Fee Rate (%) | The ongoing charge figure (OCF) for a low-cost tracker fund |
High Fee Rate (%) | The annual management charge (AMC) for an actively managed fund |
Inflation Rate (%) | Toggle on to see the real purchasing power of your future pot |
What does it show you?
Once you press Calculate, the tool produces:
Visual charts — a year-on-year line graph showing your investment growing across three scenarios: no fees, low fees, and high fees. Toggle inflation on to see all three in today's money.
Deposits vs. Interest breakdown — a bar chart showing exactly how much of your final pot came from your own contributions versus compound growth, so you can see the snowball effect in action.
Full yearly breakdown table — a detailed year-by-year table showing your portfolio value, total deposits, and total interest earned for the selected scenario, from year 0 to your chosen end year.
Impact of fees summary — a clear side-by-side comparison showing exactly how much the high-fee scenario costs you in pounds over the full investment period.

Goal-Based Planning Mode
Not sure how much you need to save each month to hit a target? Switch to Goal-Based Planning mode and work backwards.
Enter your target pot size, your expected growth rate, your fee rate, and your time horizon — and the calculator tells you the exact monthly contribution you need to reach your goal. It accounts for your existing lump sum, fund costs, and inflation, giving you a realistic, inflation-adjusted monthly savings target rather than an optimistic headline figure.
This is particularly useful for:
- Plotting the growth rate figures quoted by active or passive funds you are researching
- Comparing the real cost of a 0.1% tracker versus a 1% actively managed fund over 20–30 years
- Working out how much more you need to save each month if you start five years later
- Understanding what your current ISA or SIPP contributions will realistically be worth at retirement
