Our Mission
We built CompareStockISA to make it easier to see what different Stocks & Shares ISA platforms really cost - all in one place. We're impartial and focused only on showing platform fees clearly, never on telling you where to invest.
The Problem We Solve
Charges for Stocks & Shares ISAs can be confusing. Some platforms charge flat fees, others use percentages or tiered bands, and many add dealing charges and foreign exchange fees on top.
This makes it incredibly difficult to compare platforms fairly and understand the true cost of your investments over time.
Complex Fee Structures
- Flat fees vs percentage fees
- Tiered pricing bands
- Hard to understand dealing charges
- Foreign exchange fees
Our Solution
- Consistent estimated fee modeling
- Side-by-side comparisons
- Transparent assumptions
- Easy-to-understand results
How We Help
Our mission is simple: to take those published numbers, apply the same assumptions to each platform, and show you the results in one consistent format that makes comparison easier.
We collect fee data disclosed by Stocks & Shares ISA platforms and model estimated costs based on the information you enter, presenting everything in a clear, comparable format.
Our Values
These core principles guide everything we do
Transparency
We believe in complete transparency about how our calculator works, what assumptions we make, and where our data comes from.
Independence
We maintain complete independence from all ISA platforms. We do not receive commissions, fees, or any form of compensation that could influence our data or comparisons.
User Focus
We design our tool with users in mind, making complex fee structures easy to understand and providing clear, actionable information to help you make informed decisions.

We apply the same assumptions and methodology across all platforms, ensuring that estimated cost comparisons are fair and meaningful.
