A Minor Works utility for Chrome
Margin.
A scratch calculator and ledger for costs, comparisons, budgets and more.
Collect numbers from around the web, keep each one connected to its source, and work out what they add up to—without opening a spreadsheet.

Built for the in-between
More than a calculator.
Less than a spreadsheet.
Margin gives scattered numbers just enough structure to become useful. Make a quick comparison, plan a trip, build an estimate or keep a running tally of anything you’re figuring out.
Calculate as you browse.
Add quantities, organize items into groups and see subtotals and totals update in Chrome’s side panel.
Start with structure—or don’t.
Begin with a trip planner, project estimate or other useful template—or make a blank sheet entirely your own.
A useful place to begin
Bring the numbers together.
Margin is ready for practical jobs without deciding how you have to do them. Use a template, rename its categories, add your own—or begin from scratch.
Local by design
Your working ledger stays yours.
Margin stores your sheets locally in Chrome. It does not require an account, sell your data or send your working figures to an external service.
