CLUSTER INVESTMENT-WEB-CALCULATES · 61 ENTRIES · EARLIEST ENTRY 2026-06-20
ROI calculation web apps
The cluster consists of web apps that calculate return on investment for a wide range of contexts, from cleaning services and logistics to HR software and EV charging stations. These tools help users quantify financial gains from specific investments or business decisions, typically by entering metrics and receiving projected returns. The cluster's dated history is too thin to read a shape from, as only 2 dated entries exist before the index start, with the rest undated. Traction across members is minimal, with the highest activity signals being Painel-de-Melhorias, Q-sip-cal, and roi-calculator, all showing 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 1 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
