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.

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.
