How Crowdfunding Works
A campaign has moving parts that decide whether you keep the money: a goal, a deadline, an all-or-nothing or flexible funding model, and platform fees. Understanding these mechanics is the difference between a campaign that pays out and one that doesn't.
A crowdfunding campaign isn't just "put up a page and collect money" — it runs on a specific set of mechanics that determine whether you actually keep what you raise, and understanding those mechanics before you launch is essential, because some of them (especially the funding model) can mean the difference between getting all your money or none of it. Every campaign has a funding goal (the amount you're trying to raise), a deadline (the campaign runs for a fixed period), a funding model (all-or-nothing, where you only get the money if you hit your goal, versus flexible/keep-it-all, where you keep whatever you raise), and fees (the platform and payment processor take a percentage). How these interact shapes your whole strategy — most importantly, the all-or-nothing model means falling short of your goal by a dollar can mean receiving nothing, which is why setting the right goal (a later chapter) is so critical. This chapter explains how a campaign works so the mechanics don't surprise you.
The mechanics of a campaign
How a crowdfunding campaign actually operates:
- The funding goal. The amount you set out to raise. On all-or-nothing platforms, this is a threshold you must hit to get any money.
- The deadline. Campaigns run for a fixed period (often around 30 days). The clock creates urgency — most funding comes at the start and the very end.
- All-or-nothing vs. flexible. All-or-nothing (e.g., classic Kickstarter): hit your goal or get nothing (backers aren't charged). Flexible/keep-it-all (an Indiegogo option): keep whatever you raise, even below goal.
- Platform & processing fees. The platform takes a percentage, and payment processing takes more — budget for fees eating into your total (a later chapter accounts for this).
- Backers & pledges. Supporters pledge money, usually selecting a reward tier. Pledges are collected at the end (all-or-nothing) or as made (flexible), depending on the model.
- Payout. After a successful campaign, the platform releases the funds (minus fees) to you — not instantly, so plan for a short delay.
Why the funding model matters most
Of all these mechanics, the one that most shapes your strategy is the funding model — all-or-nothing versus flexible — because it determines what happens if you fall short of your goal, and that changes everything about how you set the goal and run the campaign. Under all-or-nothing (the classic Kickstarter model), you receive the money only if you reach or exceed your goal by the deadline; if you fall short, backers are not charged and you get nothing. This sounds harsh, but it has advantages: it protects backers (they don't pay for a film that isn't funded), it creates urgency and a clear rally point, and it signals seriousness. Its danger is obvious — set your goal too high and miss it, and a campaign that raised real money returns you zero. Under flexible/keep-it-all funding (an option on some platforms like Indiegogo), you keep whatever you raise even if you don't hit your goal; this reduces the risk of getting nothing, but removes the urgency and the "help us cross the line" momentum, and can leave you with a partial sum that isn't enough to actually make the film. The choice between them, and the goal you set within them, is one of the most consequential decisions in your campaign — which is exactly why setting a realistic, achievable goal (covered in its own chapter) matters so much, especially under all-or-nothing. A few honest points. First, all-or-nothing rewards a reachable goal — because missing means getting nothing, the smart move under this model is to set a goal you're confident you can hit (often the minimum you truly need), then let overfunding be a bonus, rather than setting an ambitious goal you might miss. Second, fees are real and must be budgeted — between the platform fee and payment processing, a meaningful chunk of what you raise doesn't reach you, so your goal must account for fees (and for reward costs), a point the budget chapter develops. Third, the deadline drives the shape of funding — campaigns typically see a spike at launch, a slower middle, and a surge at the end, so understanding this rhythm helps you plan your promotion (front-load and finish strong), which the running chapter covers. Fourth, the model shapes the psychology — all-or-nothing's "we might not make it" creates a rallying urgency that flexible funding lacks, which is why many filmmakers choose all-or-nothing despite its risk, betting that the urgency helps them succeed. Understanding how a campaign works — goal, deadline, funding model, fees, payout — means none of the mechanics blindside you, and it sets up the single most important early decision: choosing a model and setting a goal you can actually reach. With the mechanics clear, the next chapter looks at where you'll run all this: the platforms. Next, the crowdfunding platforms.
A filmmaker I knew ran an all-or-nothing campaign with a goal she'd set ambitiously, hoping to fully fund her feature in one go. She raised a genuinely impressive amount — around 80% of a high goal — and, because she'd missed the threshold, received exactly none of it. All that money, all that effort, gone, because she hadn't understood that all-or-nothing means all or nothing. Her next campaign, she set the goal at the true minimum she needed, hit it in the first week, and every dollar after that was overfunding she got to keep. Same filmmaker, same audience, completely different outcome — because the second time she understood the mechanics before she launched.
Funding Strategy helps you map where your film's money will come from — and where crowdfunding fits alongside grants, investors, and your own resources — so your campaign is one piece of a plan, not a shot in the dark.
