Pralana is respected for granular retirement tax and withdrawal modeling. RetIQ is a one-time, local model built around one clear answer.
Pralana exposes a lot of detail and lets you tune assumptions closely. RetIQ keeps engine depth but presents it as an answer first — does the plan last, what changes it — with the detail underneath.
RetIQ is a one-time purchase. Pralana is licensed by subscription.
RetIQ runs in the browser and as a native iPhone app, with the plan stored on the device. Pralana's platform and storage model are described on its site.
Pricing and features change; check Pralana's site for current details. RetIQ is not affiliated with Pralana.
