InvestBeacon, a European investor education and broker comparison platform.
Help visitors explore what regular saving, portfolio costs and inflation can mean over time. Add one calculator or a switcher with all three views.
- Compound growth: estimated final value, total contributed, and gain or loss.
- Ongoing fees: compare the same scenario with and without a percentage-based ongoing fee. See direct charges separately from the total effect on compounding.
- Purchasing power: compare nominal value with an inflation-adjusted estimate in today's money.
- Change initial investment, monthly contribution, duration, annual gross return, ongoing fee, inflation and contribution timing.
- View a chart, an accessible annual table, and download annual figures as CSV.
- Choose from 11 display currencies. This changes the unit shown, with no exchange-rate conversion.
- Use multiple independent calculators on the same page.
- No account, API key or paid service is required.
Add the Investment Calculator block in the editor, or use:
[investbeacon_calculator]
[investbeacon_compound_interest]
[investbeacon_fee_impact]
[investbeacon_inflation]
Example with custom defaults:
[investbeacon_calculator initial="10000" monthly="300" years="25" rate="6" fee="0.2" inflation="2" currency="EUR" timing="end"]
The editor block displays an explanatory placeholder and controls for default assumptions. Open Preview or the published page for the interactive calculator.
Privacy
Calculations happen in the visitor's browser. The plugin does not send calculation inputs to a server, store visitor inputs, set cookies, use browser storage, include analytics, call an external API or load remote scripts, fonts or calculation data. All plugin assets are served by your WordPress site.
Default assumptions chosen by a site editor are stored in the normal WordPress page/post content. They are not visitor submissions. CSV exports are generated locally and saved only when a visitor requests a download. WordPress, your hosting provider and other plugins can have separate data practices.
The optional front-end credit link is off by default. Enable the block's credit toggle or add credit="true" if you want it. Clicking that link opens
InvestBeacon as an ordinary website visit; calculator values are not attached to the link. There are also ordinary website/support links on the administrator help page. The calculator does not contact InvestBeacon in the background.
Model and limitations
Returns, ongoing fees and inflation are constant annual assumptions, converted into equivalent monthly factors. Contributions arrive at the beginning or end of each month, as selected. Values are calculated without intermediate rounding. Today’s-money values discount the future balance for accumulated inflation; contributions remain fixed in nominal terms.
This model excludes tax, dealing commissions, FX charges, cash withdrawals, contribution increases and variable returns. The ongoing fee is a percentage of the portfolio, not a flat dealing fee. Currency selection does not convert amounts.
These are illustrative estimates, not forecasts or investment advice. Actual returns vary and losses are possible. InvestBeacon and Athanasios Karantonis do not recommend any investment through this plugin.
