Most studios decide their ad budget by looking at what's left in the bank, then panic-spend it in launch week. That's backwards. A game marketing budget is a plan you build against your wishlist goal and your runway and when you size it right, every dollar has a job before it's spent.
Start From The Wishlist Goal, Not The Bank Balance
Before you pick a number, decide what the money is supposed to buy. For a Steam launch that almost always means wishlists, because wishlist volume and velocity in the final week drive your visibility in Popular Upcoming and your day-one discount traffic. So work backwards: pick a wishlist target, estimate a realistic cost per wishlist for your genre (anywhere from $0.30 to $2.00 depending on appeal and creative), and you have a paid budget floor.
Run that math early. A rough Steam Wishlist Calculator pass on your genre and price point tells you whether a 30,000-wishlist goal needs $15k or $50k of paid support and whether that's even reachable with what you have. If the number is impossible, it's far better to learn that 12 months out than 3 weeks out.
Split The Budget By Phase, Not Evenly
A flat monthly spend wastes money. Paid acquisition compounds when it has a destination a polished page, a demo, a festival slot so weight your budget toward the moments that convert. A practical split for most indie and AA Steam titles looks like this:
- 10 15% early testing, 6+ months out: small spends to validate creative, hooks, and audiences while stakes are low.
- 15 20% page and demo warm-up: drive traffic once your capsule, trailer, and demo are genuinely good, not before.
- 40 50% the launch window: the two weeks before and the week after release, when wishlist velocity and reviews matter most.
- 15 25% post-launch reserve: retargeting, sale events, and scaling whatever channel actually worked.
Notice the reserve. The single most common budget mistake is going all-in on launch day with nothing held back. The data you need to spend efficiently only exists after launch keeping a quarter of your budget dry lets you double down on a proven winner instead of guessing in the dark.
Set A Floor You Can Actually Test With
There's a minimum below which paid ads can't teach you anything. Spreading $500 across three platforms and five creatives gives you noise, not signal. As a rule of thumb, budget enough that each channel you test gets at least a few hundred dollars and a couple hundred conversions before you judge it otherwise you're reading tea leaves.
If your total budget is small, the answer isn't to spread it thinner. It's to pick one channel, learn it properly, and only expand once it's working. A focused $3k that produces a repeatable cost per wishlist beats a scattered $10k that taught you nothing.
Build In The Costs That Aren't Ad Spend
Your media budget is not your marketing budget. Ad platforms only do their job when the assets feeding them are strong, so reserve real money for the things that make spend efficient: trailers, capsule art, a handful of static and video ad variants, and the time to manage campaigns. A clean Paid Ads Setup with proper conversion tracking and a tested creative set will routinely cut your cost per wishlist in half which means production spend is acquisition spend in disguise.
- Creative production: trailers, key art, and ad-specific variants you'll actually test.
- Tooling and tracking: pixels, UTMs, and the analytics to attribute results.
- Management time: yours or an agency's campaigns left on autopilot leak money.
- A contingency line of 10 15% for the channel or moment that surprises you.
Decide When To Spend, And When To Wait
A budget is also a set of stop conditions. Don't pour money into a page with a weak conversion rate, a trailer that isn't landing, or a genre fit you haven't validated fix the leak first, then open the tap. Price matters here too: your discount and launch price shape how much each wishlist is worth, so a quick Steam Pricing Planner check helps you decide what a wishlist is actually worth paying for.
Sizing a budget is mostly about honesty: a real wishlist goal, a real cost per wishlist, and a real reserve for what you'll learn after launch. If you'd like a second pair of eyes on those numbers before you commit, that's exactly the kind of thing we're happy to look at with you.
