How we make money

PlugPayback is free, has no sign-up and no ads inside the calculator. Here is how it pays for itself.

Affiliate links

When a result shows kits that fit, some links are affiliate links. If you buy through one, the shop pays us a commission, typically 5–10% of the price. Your price does not change. Affiliate links are always labelled.

What commissions never do

• They never change the order. Kits that are allowed where you live and deliver at least the power you chose are listed cheapest first. If a brand we have an affiliate deal with sells a matching kit, its cheapest one is listed too, in its place by price.
• They never change the payback number. The calculation is the same whether a kit has an affiliate programme or not, and the formulas are on the methodology page.
• They never change the verdict. If a kit is a weak investment at your home, the result says so.

What we do not do

No installer lead forms, no selling of your data, no email capture, no sponsored rankings. Shared result links contain only your inputs and a coarse location (first postcode digits or your state), never an address.
