From September 2025 to August 2026, a unique lead in Poland cost between $5 (20 PLN) and $45 (169 PLN) in our campaigns. The cheapest leads were for WIBOR loan litigation and the most expensive for foreign-currency mortgage litigation. Seven of the ten industries we ran landed between $13 and $32. We calculate every figure the same way: client ad spend divided by unique phone numbers in our lead database.
In short:
- A unique lead in Poland cost $5 (20 PLN) for WIBOR loan litigation and $45 (169 PLN) for foreign-currency mortgage litigation in our campaigns from September 2025 to August 2026.
- Residential solar cost $32 (121 PLN) per unique lead, mortgages $25 (92 PLN), and accounting firms $15 (58 PLN).
- These are costs per unique phone number, not per form submission, so they are higher than the CPL shown in Meta Ads Manager.
How much does a lead cost in Poland by industry?
It ranges from $5 to $45, and the industry decides where you land, not the country. Anyone who quotes you a single "cost per lead in Poland" is giving you an average that describes no real campaign.
Here is every industry we ran over those 12 months. The data comes from our panel: client ad spend and unique phone numbers in the lead database. We converted PLN to USD at 1 USD = 3.7404 PLN, the National Bank of Poland average for June to September 2026.
| Industry | Cost per unique lead (USD) | Cost per unique lead (PLN) | Unique leads | Ad spend (USD) |
|---|---|---|---|---|
| Foreign-currency mortgage litigation (law firms) | $45 | 169 PLN | 2,127 | $96,244 |
| Residential solar | $32 | 121 PLN | 2,831 | $91,801 |
| App development (software houses) | $32 | 118 PLN | 666 | $21,012 |
| Mortgages | $25 | 92 PLN | 1,109 | $27,346 |
| Debt restructuring | $19 | 70 PLN | 1,571 | $29,474 |
| Business loans | $18 | 67 PLN | 891 | $15,975 |
| Accounting firms | $15 | 58 PLN | 896 | $13,803 |
| Leasing | $13 | 47 PLN | 519 | $6,572 |
| Consumer bankruptcy | $8 | 28 PLN | 596 | $4,514 |
| WIBOR loan litigation (law firms) | $5 | 20 PLN | 1,219 | $6,657 |
Small samples move more. App development at 666 leads and leasing at 519 leads are less stable figures than solar at 2,831. Treat them as a starting estimate, not a quote.
We should be clear about our interest: we earn money on Meta and Google Ads campaigns and lead packages in these industries, so a table that makes Poland look affordable is good for our business. That is why we publish spend and lead counts next to every price, including the 2,831 residential solar leads behind the solar figure, so you can check the arithmetic yourself.
Is a lead in Poland cheaper than in the US?
We don't measure that in this dataset, so we won't claim it. This table covers Polish campaigns only. Putting a made-up US benchmark next to it would turn a data article into a sales pitch.
What we can say from the numbers we have:
- The dollar price moves with the zloty. Every USD figure here depends on the 3.7404 rate. If the zloty strengthens against the dollar, the same 169 PLN lead costs you more dollars, even though nothing changed in the ad auction.
- Compare per industry, never per country. Within Poland, a legal lead cost anywhere from $5 to $45. A US comparison that ignores the industry tells you nothing.
- Compare the same definition. If a US vendor quotes cost per form submission and we quote cost per unique phone number, the two numbers are not the same thing. More on that below.
If you already buy leads in the US, the honest test is simple. Take your own US cost per unique lead in the same industry and put it next to the matching row above.
Why is a unique lead more expensive than the CPL in Meta Ads Manager?
Because Meta counts form submissions and we count people. The CPL in Meta Ads Manager is the cost of a submitted form before anyone has checked it. The same person can submit twice, from two ads, a week apart. Meta counts both. We count one phone number once.
This table shows only the cost per unique lead. We are not publishing the Meta-reported CPL for these campaigns here, so we won't put a number on the gap. The direction is fixed, though: the platform figure is always lower than the unique figure, because duplicates get divided out.
Our position: a lead price that counts the same phone number twice is inflated, and buyers pay for it. When you compare offers from Polish vendors, ask one question first: is this price per form or per unique phone number? If they can't answer, assume per form.
Why are legal leads in Poland both the most expensive and the cheapest?
Because they are two different markets that happen to share the word "litigation". Some context for readers outside Poland:
- Foreign-currency mortgage litigation means lawsuits brought by Poles who took mortgages indexed to the Swiss franc or other foreign currencies and are now suing their banks. This has been one of the biggest consumer litigation waves in the country. A unique lead cost $45 (169 PLN) here, the highest in our table, across $96,244 of spend.
- WIBOR loan litigation covers lawsuits in which borrowers challenge clauses tied to WIBOR, the Polish benchmark interest rate. A unique lead cost $5 (20 PLN) across 1,219 leads.
We can measure the price gap. We can't measure the reason behind it from ad accounts alone, and we won't pretend we can. What follows for a buyer is practical: a $5 lead and a $45 lead from "Polish law firms" are not comparable products. Judge each one by what a signed case is worth to you.
Which Polish industries are cheapest to generate leads in?
In our data: WIBOR litigation at $5 (20 PLN), consumer bankruptcy at $8 (28 PLN), and leasing at $13 (47 PLN). Accounting firms followed at $15 (58 PLN) and business loans at $18 (67 PLN).
Cheap is not the same as profitable. A low cost per lead in debt-related services ($19, or 70 PLN, for debt restructuring) still has to survive your contact rate and close rate. We don't measure our clients' close rates in this dataset, so we can't tell you which row is the best business. We can tell you what reaching a person costs.
To budget, multiply the cost per unique lead in your row by the number of leads your team can actually call back in a month. Don't size the budget by what you hope to spend.
When does buying leads in Poland not make sense?
It doesn't make sense when nobody on your side can call these people back in Polish. Every lead in this table is a phone number. A lead that sits uncalled for a week is money spent on nothing, whether it cost $5 or $45.
Skip it, too, when one closed deal can't cover the cost of the leads it takes to close it. If you sell a low-margin service in an industry priced at $32 per lead, such as solar or app development, do that math before you spend anything.
In those cases, do this instead: hire or contract a Polish-speaking intake person first, or test with a small campaign in one of the cheaper rows to learn your own close rate before you commit budget to the expensive ones.
We are changing one thing about how we report this. We will keep publishing cost per unique phone number, never cost per form, and we will put spend and lead counts next to every price so anyone can check the division.
FAQ
What is the average cost per lead in Poland?
We don't publish a single average, because it would mix $5 legal leads with $45 legal leads and describe neither. Across our ten industries, the cost per unique lead ranged from $5 (20 PLN) to $45 (169 PLN). Seven of the ten landed between $13 and $32.
How much does a solar lead cost in Poland?
In our campaigns from September 2025 to August 2026, a unique residential solar lead cost $32 (121 PLN). That figure comes from 2,831 leads and $91,801 in ad spend.
Are these lead prices what Lemon Agency charges for lead packages?
No. These figures are client ad spend divided by unique phone numbers, which is the media cost of a lead. They are not our package prices.
What exchange rate did you use to convert PLN to USD?
We used 1 USD = 3.7404 PLN, the National Bank of Poland average for June to September 2026. If the rate changes, the PLN figures stay the same and the USD figures move with it.
