What Types of Tools and Calculators Does Protoolio Offer?

Updated

Protoolio is a collection of 100+ free and premium business and productivity tools organized into four main groups: apps, calculators, generators, and cheatsheets. It covers finance and accounting, marketing and growth, startup and equity, and personal productivity. The site says it is used by 100,000+ professionals in 193 countries. The tools are aimed at business professionals, marketers, startups, and entrepreneurs, so it is most useful if you want a quick, single-purpose utility rather than a full accounting or marketing platform.

Finance and accounting tools

This is the largest cluster on the site. It includes:

  • Financial Statement Builder and Financial Statement Templates — a bundle for assembling company financial statements
  • Income Statement Generator — produces an income statement for your company
  • Balance Sheet Generator — produces a balance sheet for your company
  • Markup Calculator — works out markup on cost
  • Revenue Forecast — projects future revenue
  • Stock Portfolio Analyzer and Stock Split Calculator — portfolio and share-split math
  • FIRE Calculator — models a path to financial independence
  • US Economic Dashboard — a reference view of US economic data

These are generators and calculators, not a bookkeeping system. You supply the inputs and get a formatted output or a number; nothing suggests they store your books or sync with accounting software.

Marketing and growth calculators

For marketers, the site lists:

  • CAC — customer acquisition cost
  • CTOR — click-to-open rate for email
  • Google AdSense — expected AdSense revenue
  • Marketing Benchmarks — compare your performance against industry standards
  • Alt Text Generator — AI-generated, SEO-friendly image alt text

The pattern is the same: each tool answers one narrow question. Marketing Benchmarks is the one to check first if you want context for your own numbers rather than a single calculation.

Startup and equity tools

Aimed at founders and employees with equity:

  • RSU Calculator — values restricted stock units
  • Startup Equity Calculator — splits and dilution math for founder/employee equity
  • CMGR Calculator — compound monthly growth rate
  • Revenue Forecast — also relevant here for planning

If you are comparing offers or modeling a cap table scenario, the RSU and Startup Equity calculators are the entry points; CMGR is the one to use when you want a monthly growth figure rather than an annual one.

Productivity apps and integrations

Beyond calculators, Protoolio hosts small apps and integrations:

  • Analytics for Todoist — reporting on your Todoist tasks
  • Todoist Fast Task Creator — quicker task entry
  • Snapshots for Oura Ring — saved views of ring data
  • Temporary Links — create a temporary link with a message or redirect
  • Google Direct Links — generate a direct download link for Google Drive files
  • Preset Extractor — a free Lightroom preset extractor and JPG-to-XMP/LUT converter

These are the tools that connect to another service, so they depend on that service being part of your workflow already.

How to decide whether it fits

If you need… Start with Condition
A formatted income statement or balance sheet Income Statement / Balance Sheet Generator You already have the underlying figures
To know your cost to acquire a customer CAC calculator You can supply spend and new-customer counts
To value an equity offer RSU or Startup Equity Calculator You have grant size and share/valuation inputs
A monthly growth rate CMGR Calculator You have start and end values over a known number of months
Faster Todoist or Oura workflows The matching integration You already use that app
A one-off utility (temp link, alt text, file link) The featured tools No account requirement is stated on the page

Two practical notes before you invest time. First, the site describes its catalog as "free and premium," and a payment-fees tool is linked, so some tools may sit behind payment — the page does not specify which ones are premium, so check the individual tool page rather than assuming everything is free. Second, the tools are deliberately small and single-purpose ("Small tools. Big difference."), which makes them fast to use but means no tool replaces a full platform for accounting, CRM, or analytics.

A reasonable way to test the site is to pick the one calculation you need this week — say a CAC figure or a balance sheet — run it, and judge the output before exploring the rest of the catalog.
