Proof Gap Cost Calculator

Discover your estimated time and money spent on ESG and compliance work.

What Manual Proof Work Costs Your Team

Manual proof work quietly costs a large enterprise around 10,000 hours and six figures every year. Sustainability, compliance, and procurement teams lose that time gathering evidence, answering customer and investor questionnaires, and preparing for audits, usually rebuilding answers they have already produced.

The Proof Gap Cost Calculator turns that hidden cost into a number for your own team: enter your team size, region, and the share of time you spend on proof, and it returns your annual hours, your cost in euros or dollars, and how much you can recover by keeping proof in one reusable library instead of scattered across files and inboxes. Estimates draw on 2025 salary benchmarks and aggregated Sunhat customer data, updated for 2026.

Frequently Asked Questions

What is the Proof Gap?

The proof gap is the gap between knowledge and being able to prove it. : gathering evidence, answering questionnaires, and preparing for audits, often rebuilding the same answers every cycle. In a large enterprise it adds up to roughly 10,000 hours and six figures a year.

How does the Proof Gap Cost Calculator work?

You enter three things: how many people work on ESG, compliance, and proof, your region, and the share of their time that goes into proof work. The tool multiplies your team's productive hours by that share and a loaded hourly rate for your region, then shows your annual hours, cost, and how much you can recover.

How accurate are the numbers?

The result is a directional estimate, not an audited figure. It draws on 2025 salary benchmarks, standard full-time working hours, and aggregated Sunhat customer data, and every input is editable so you can match your own team. Use it to size the opportunity, not to close your books.

How can we reduce our Proof Gap?

Most of the lost time is rework: searching for the right file, chasing approvals, and re-sending answers you already have. Teams that keep proof in one reusable, verified library instead of scattered files report cutting that effort by 50 to 60 percent. That is what Sunhat's Collaborative Proof Platform is built to do.
