Finance affiliate programs with the longest cookie windows, and what they cover
By the LinkedAffiliate team ·
Someone reads your comparison of savings accounts on a Sunday evening, clicks through, closes the tab and goes to bed. Three weeks later, after talking it over and checking their own bank, they come back and open the account. Whether that sale is yours depends almost entirely on one number: how long the program remembers your click.
People take longer over money than over almost anything else they buy online, which is why the cookie window matters more in finance than in most categories. This page lists the finance programs in our directory with the longest published windows, then covers what decides whether a long window actually pays you: when the program counts the referral, how it handles app sign-ups, and who else is chasing the last click.
Finance affiliate programs ranked by cookie window
These are the 5 finance programs in the directory with published terms, longest cookie window first. Each name links to its listing, which shows every program the company runs, the terms we read and the page we read them from.
| Program | Best rate | Cookie window | Networks |
|---|---|---|---|
| XTB.com | 0.2% | 364 days | Direct (in-house) |
| BillingNow | 35% | 90 days | Direct (in-house) |
| simplywall.st | See listing | 90 days | Direct (in-house) |
| SparkReceipt | See listing | 60 days | Direct (in-house) |
| Coinpanda | See listing | 7 days | Direct (in-house) |
Here is how the category looks as a whole:
- Programs with published terms
- 5
- Median best commission
- 0.2%
- across 2 programs that publish a percentage
- Median cookie window
- 90 days
- across 5 programs that publish one
A program shown as "Not published" did not state a window on the page we read, which is not the same as having none. Finance programs often keep the full terms in the agreement or show them only after you are approved. The list is also not every finance program in the world, and it changes as we add programs and as companies correct their own listings. Treat it as a shortlist, then read each source page before you build content around one.
If you care more about the payout than the window, our guide to the highest paying finance affiliate programs ranks the same category by commission.
Why finance readers take their time
Opening a bank account, taking out a loan, picking a broker or moving a pension are decisions people sleep on. They compare two or three options, read the small print, ask a partner, wait for payday or for a statement to arrive. Some of them need documents they do not have to hand.
Every one of those pauses happens after your click. A short window can run out in the middle of a perfectly normal decision, and the account then gets opened with no affiliate attached. Our cookie windows explainer covers the mechanics (when the clock starts, what resets it, how last click works). This page is about how those mechanics play out when the product is money.
Does the application have to be approved inside the cookie window?
Usually not. Most finance programs need the application, sign-up or lead to happen inside the window, and then follow that application through approval or funding, even if the decision lands weeks later. Some programs do say the qualifying step itself must happen inside the window, so check the wording before you count on it.
This matters because finance programs rarely pay on the first click that converts. They pay on an approved card, a funded account, a first deposit or a first trade. Those steps can take days or weeks after the application, especially when identity checks or credit checks are involved. Look for the line in the terms that says when a referral is "tracked" or "attributed", and separately for the line that says what makes it "qualify". They are often two different moments, and only the first one has to fall inside the window.
App sign-ups and the cookie that does not follow
A cookie lives in one browser. A lot of finance products, from banking apps to trading platforms, push new customers to finish sign-up in a mobile app. If your reader clicks in a phone browser, then installs the app and signs up there, the browser cookie may never be seen.
Programs handle this in different ways, and the terms usually say which one applies:
- Install attribution. Some programs track through the app store install and credit you if the app is opened within a set period. That period is its own window, often shorter than the web cookie.
- Web-first sign-up. Some programs keep the first sign-up step on the website, so the account is tied to you before the reader ever opens the app.
- Referral codes. A few let you give readers a code to enter during sign-up, which works across devices and apps. A code is worth more to you than a long cookie the app cannot read.
If a program's terms talk only about cookies and the product lives mostly in an app, ask the program team in writing how app sign-ups are credited before you plan around it.
Comparison and cashback sites take the last click
Finance has a lot of comparison sites, cashback portals and voucher pages, and many of them sit right at the end of the buying journey. A reader who learned about a product from your guide may still search for a bonus or a cashback offer before they apply. On a program that credits the last click, that final visit wins, however long your window was.
A long window cannot protect you from that. What helps is reading the attribution rule: last click, first click, or a split. It also helps to know whether the program lets cashback and voucher sites join at all, since some finance programs exclude them or limit them to certain offers. That is usually written in the program's terms or its list of allowed traffic sources.
Regulated products and how they track
Financial products are regulated, and the rules affect how some programs work. Some providers only accept affiliates in certain countries, some send leads through an approved introducer rather than a plain tracking link, and some keep the referral process inside their own application form. Each of those can change what the cookie window means in practice.
The same advertising rules apply as on any finance program: required risk warnings, no promises about returns or approvals, approved wording where the program asks for it, and a clear affiliate disclosure near the link. A long window does not loosen any of that.
A long window does not change what happens after the sale
Once the referral is credited, the cookie has done its job. What you earn from there depends on other terms: whether the program pays once or keeps paying, and on what. Our guide to finance affiliate programs with recurring commission covers subscriptions, revenue share and insurance renewals.
When you are paid is another separate question. Finance programs often hold commission for a while to watch for fraud and early closures, and a long cookie window says nothing about how long that hold is. Our guide to affiliate payout terms explains holds, thresholds and net terms.
Checking the window before you join
Five questions to answer from the program's own pages before you write about it:
- How many days is the window, and is it on the public page or only in the agreement?
- Does the application have to happen inside the window, or the approval or funding too?
- If customers finish sign-up in an app, how is that credited, and is there a separate install window?
- Does the program use last click, and does it accept cashback and voucher sites?
- Are there countries or products where the program tracks differently, or not at all?
Most of these answers sit in the affiliate agreement rather than on the sign-up page. Our guide on how to read an affiliate agreement shows where each clause usually lives.
Where to go from here
Browse every program in the finance category, open the listings with the longest windows and check how each one credits an application. A long window on a program that tracks at sign-up is worth more than an even longer one that waits for approval.
