How much to invest in user acquisition.

If you pick one, lead with payback. It answers the question finance is asking, which is how long the cash is out, and it does not depend on retention, the least reliable input in most markets. Use the LTV-based CAC ceiling to size a budget around a growth target once you trust your LTV. Most brands benefit from running both.

Yes. The math is the same. For iGaming, a new depositing user is a first-time depositor and revenue is gaming revenue. For fintech, it is a first funded account or first transaction, and revenue is fees, spread, and interest. Fintech margins vary more by product, so replace the 20% default with your own.

New entrants pay more per user while channels are tested, and most early users land in the lowest-value tier. Treat every input as an estimate and start with a test budget.

Growth-stage brands usually see their lowest acquisition costs as proven channels scale. This is the stage to replace estimates with measured cohort data.

Mature brands often face rising acquisition costs as core audiences saturate, but recover spend faster because more of each cohort reaches high-value tiers. In our Philippine iGaming data, blended payback ran about 14 months at a newer operator and about 1.5 months at a mature one.

3:1 is a widely used planning benchmark that leaves room for operating costs and users who churn early. It only works with an LTV that captures the full value of a user.

In our cost per FTD benchmark, every measured LTV:CAC in Philippine iGaming came in below 1. The standard formula misses users who return, users who move into higher tiers, and users who stay far longer than average. If your LTV comes from that formula, 3:1 sets a very low ceiling. Use a fuller LTV, or lead with payback.

₱800 is a starting reference for Philippine acquisition. Across four iGaming operators in our benchmark, cost per FTD ranged from $6.44 to about $25, and ₱800 falls inside that range. Your real figure depends on product, channel mix, user quality, and where regulation lets you advertise. Replace it with your own as soon as you have it.

Payback is CAC divided by monthly contribution per user, so retention does not enter the formula. Retention figures move a lot depending on how you define an active user, and payback stays reliable when that data is weak. The cash plan assumes each month’s new users keep producing at your stated rate until they pay back. If many churn in the first month, recovery takes longer than shown.

Pull your earliest cohorts and track their revenue month by month. Three months of data is enough for a first estimate. If you are pre-launch, use the example numbers to plan a small test budget, then rerun the calculator once real cohort data comes in.

Yes. These two are the simplest to start with. As your data matures, these methods add precision.

• Diminishing returns curves. Plot spend against new users by channel and stop adding budget when the next ₱100,000 costs more per user than your ceiling allows.
• Incrementality testing. Run spend in some regions or audiences and hold it back in others to measure what marketing actually caused.
• Test, prove, scale. Start with a fixed test budget, expand only the channels that hit target, then scale with clear gates.
• 70/20/10 allocation. Put 70% into proven channels, 20% into promising ones, and 10% into experiments.
• Bayesian allocation. Budget shifts automatically toward the channels or affiliates that perform, while newer ones keep a small share to prove themselves.
• Marketing mix modeling. A statistical model of each channel’s contribution over time. It needs one to two years of clean data, so it suits mature brands.
• The Kelly criterion. An unconventional option borrowed from professional betting and quant funds. It sizes each spend cycle by how often campaigns win and by how much. We use it as a pacing check, usually at half strength, because the inputs are estimates.

No. It is a planning estimate. The calculator holds CAC flat as spend grows. In practice, costs usually rise as you reach further into an audience, so scale large budgets in stages and check them against real results.

Indirectly. Regulation limits which channels you can use, and that shows up in your CAC. If your CAC comes from compliant channels, the budget it produces is built on compliant spend. Rules are shifting on both sides, from proposed limits on online gambling advertising to BSP’s draft payment rules, so revisit your inputs when they change.

Yes. It is the first step of every engagement. We instrument acquisition so each source ties to downstream user behavior, then replace every estimate on this page with a measured figure.
