## The Tools

You shouldn't have to pay a fortune to do basic maths. We built these calculators because we got tired of seeing people do back-of-the-envelope calculations that ended up wrong. Use them. Make better decisions. They're free.

### Scrap Rate Calculator

{{< iframe src="https://app.gosmarter.ai/scrap-calculator" title="Scrap Rate Calculator" >}}

Standardise scrap calculations across your operation and get consistent scrap-rate and cost reports to support improvement work.

### Metals Emissions Calculator {#steel-emissions-calculator}

{{< iframe src="https://app.gosmarter.ai/emissions-calculator" title="Emissions Calculator" >}}

Find out exactly how much CO₂ your metal orders are generating. Covers steel, aluminium (with regional grid factors), copper, copper-nickel, and brass/bronze alloys. Enter the material, weight and process, and stop guessing when sustainability reporting comes round.

### Business Case Calculator

{{< iframe src="https://app.gosmarter.ai/business-case-calculator" title="Business Case Calculator" >}}

Build a business case that actually gets sign-off. Cost and benefit breakdown, exportable as PDF or a shareable link, so the people holding the budget can't say they didn't understand it.

### Steel Grade Converter

Quickly convert between steel grade naming conventions and equivalents to help match materials and specifications.

### Metal Weight Calculator

{{< iframe src="https://app.gosmarter.ai/metal-weight-calculator" title="Metal Weight Calculator" >}}

Calculate the mass of common metal shapes and profiles for 12 metal types, including steel, stainless, aluminium, copper, copper-nickel (Cu-Ni), and aluminium-bronze (Al-Bronze), with results in kg, lbs, and linear weight (kg/m and lb/ft). Round tube now supports NPS/Schedule, DN/Standard, and Copper Type K/L/M/DWV pipe lookup modes alongside manual OD/wall entry. For reinforcing bar, select round bar and enter the nominal diameter (H10, H12, H16, H20, H25, H32, H40) to get the weight per metre and total bar weight instantly. Useful for order estimating, bending schedule checks, and material accounting without touching a spreadsheet.

### Compliance Checklist

Compliance paperwork is dull. Missing it is expensive. Run through the checklist (certificates, traceability, documentation) and know your deliveries are actually covered.

### Material Yield Planner

{{< iframe src="https://app.gosmarter.ai/material-yield-planner" title="Material Yield Planner" >}}

Plan parts from sheets or slabs while accounting for cutting loss (kerf) to reduce scrap and estimate usable leftover material.

### Manufacturing Cost Calculator

{{< iframe src="https://app.gosmarter.ai/manufacturing-cost-calculator" title="Manufacturing Cost Calculator" >}}

Estimate manufacturing costs (material, processing, and labour) so your quotes don't leave money on the table.

## Want more than calculators?

These tools are free because we want you to see what GoSmarter can do. When you're ready for real-time inventory, automated cert reading, or AI-powered cut planning, we have paid products that go much further. For AI-powered compliance and traceability, GoSmarter starts at £150/month with 50% off your first month.

The free tools work best as a starting point. Use the scrap rate calculator to understand your current waste levels, then try Cutting Plans to see how much you could save with a better cut plan. Use the business case calculator to build the numbers for sign-off, then get started on a free trial.
