The idea is to let users test the Index "for fun". Like a demo in the web.

Starting value
a field for the amount , a drop down menu for the currency

Target country
drop down for the list of countries

Result
a field for the the amount in the new currency

- - - - - - - - - -
=> for registered users

Web based UI. One price submitted, a table (.csv) is produced and downloaded

• 2 fields for the amount and currency

• Target countries: Ideally a list of country and check boxes to indicate the target countries the user wants its price to be "converted" to.

• A download button

API ?

Upload a series of prices, table, => get teh table in return with the selected countries

We could offer to start, 3 presets to modulate the calculation and application of the index.

Full Flat:
The way the Index is showing reality. With its extremes (?) and full scope.

Full moderated
The same index but with extremes brought back to the center, keeping the same shape, but reducing the scope of the curve ?

Robin Hood
Where the price stays low for the countries under the 100 average in the full flat, but where they ae calculated with a bigger stretch above the 100

Grabbing data (via API) from

  • Numbeo
  • OECD
  • WorldBank
  • ....

- set up the "100", central value ?
- calculate the raw value for each countruy
- round up per currency ...
- round up for stores.

- pure ricing ( rounding up by currency only)

- ".99" ( rounding up by currency only + marketing adjustment )

- To store ( Apple price table as reference )
