Gutter Slope Calculator
Find the correct gutter fall per metre for proper drainage.
About Gutter Slope Calculator
Dividing the total by the quantity gives the true per-unit figure for Gutter Slope, which is the only honest way to compare differently sized options. Unit figures expose value differences that headline totals hide, because larger batches are not always cheaper.
Formula
Gutter Slope
Cost per unit = total amount / quantity
- standard size
- The base amount used to normalize the per-unit figure
Worked example
With the default values below, Gutter Slope Calculator returns Cost per Unit of $20.000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
