We do not offer a calculator tool for capacitive sensors at this time.
On a related note, we suggest using the FDC1004 over the FDC2xxx devices.
Many of our customers have struggled getting to production with the FDC2xxx because of their sensitivity to EMI.
The FDC1004 has active shield drivers, which help reduce & manage EMI effects.
You can find additional information about the FDC1004, collateral and reference designs at the FDC1004 Capacitive Sensing FAQ page.
