Your numbers
Fields start empty; the worked example uses illustrative numbers, not a measured result.
Points, not percent: 0.5 means 20% → 20.5%, not 20% → 20.1%.

If you want to test a change like this, measure it against a comparable period and a control store, not against last month.
How it is calculated
Contribution = visitors × Δpp ÷ 100 × AOV × margin − extra costs.
Worked example
10,000 visitors, a 0.5 percentage-point conversion change, ₹1,200 average order, 40% contribution margin, ₹5,000 of extra costs.
50 extra orders, ₹19,000 contribution a month — a scenario you chose, not evidence that cameras caused it.

What this does not tell you
A scenario, not evidence that cameras cause sales. PGAK does not claim a retail uplift product.
Published because buyers need the number. It is not a claim that PGAK sells a product for it.
