Three calculators in one plugin
Each one comes with a chart and an accessible annual table.
Compound growth. Estimated final value, total contributed, and gain or loss from a starting amount and monthly contributions.
Ongoing fee impact. The same scenario with and without a percentage-based ongoing fee, showing direct charges separately from the total effect on compounding.
Purchasing power. Nominal value next to an inflation-adjusted estimate in today's money.
Chart, table and CSV. A chart, an accessible annual table, and a CSV download of the annual figures generated in the browser.
11 display currencies. EUR, GBP, USD, CHF, PLN, SEK, DKK, NOK, CZK, HUF and RON. Selection changes the unit shown; amounts are not converted.
No external services. No account, API key or paid service. The plugin sets no cookies, includes no analytics and loads no remote scripts or fonts.

What to tell your readers
Results are illustrative estimates, not forecasts or investment advice. Actual returns vary and losses are possible. Input limits apply, for example a duration of 1–60 whole years and an annual ongoing fee of 0–10%.
