The cheapest way to run Facebook ads
There are four ways to get a Facebook ad live: learn Ads Manager, pay a subscription tool, hire an agency, or use a pay-as-you-go launcher. They cost very different amounts at different budgets. Enter yours and see the real numbers.
What you plan to give Meta each month, before any fees.
Management cost per month, excluding the ad spend itself (you pay Meta that under every option). Subscription figure uses a $49 entry tier; many tools charge more as spend grows. Agency figure uses a $500 minimum retainer, the low end of typical.
The four ways, honestly compared
| You pay | Up-front risk | Your time | Best when |
|---|---|---|---|
| DIY Ads Manager — $0 in fees | Mis-built campaigns waste real budget | Hours to learn, ongoing to manage | You enjoy this and have the time |
| Subscription tool — $49–$259/mo | Fee due whether or not ads run | Medium — still assumes ad knowledge | You spend over ~$245/mo and know ads |
| Agency — $500–$2,000+/mo | Retainer due regardless of results | Low, after onboarding | Budget well into four figures monthly |
| Five Minute Ads — 20% of spend | $0 when ads are not running | Minutes — one form builds the campaign | You want a real ad without the learning curve |
Where each option wins
The honest math: a percentage fee is cheapest at small budgets and gets less attractive as spend grows. At 20% the crossover with a $49 subscription sits around $245 a month of ad spend — below it, pay-as-you-go wins; above it, a flat subscription costs less if you are happy building and managing campaigns yourself. That skill gap is the real price tag: subscription tools are cheaper fees on top of work you still do, while a one-form launcher includes the work. Agencies never win on price at small budgets — you hire one for hands-off scale, not savings, and typically only once spend clears a few thousand a month. If that is you, our agency vs DIY guide covers when the retainer is worth it.
Why no subscription?
Small-business ad budgets are seasonal: a café pushes before summer, an accountant before tax season. A subscription charges you in the quiet months too. A fee on spend means the tool costs exactly zero when you are not advertising. You fund a prepaid wallet (from $5), launch from one form instead of Ads Manager, and Meta bills your own ad account for the spend itself — no markup hiding in the middle.

Questions, answered
What is the cheapest way to run Facebook ads?
It depends on your monthly ad spend. Doing everything yourself in Ads Manager is free but costs hours of learning. Below roughly $245 a month in spend, a pay-as-you-go tool with a percentage fee (like Five Minute Ads at 20%) is cheaper than a subscription tool. Above that, an entry-tier subscription can work out cheaper on fees, if you are comfortable building campaigns yourself. Agencies only make financial sense once your budget is well into four figures a month.
How much do Facebook ad tools cost per month?
Subscription tools like AdEspresso, Revealbot, and Madgicx typically start at about $38 to $99 a month and scale with your ad spend, reaching $250 or more at higher tiers. Five Minute Ads has no subscription: you pay a percentage fee only on the ad spend you actually fund.
How much does a Facebook ads agency cost?
Most agencies charge a monthly retainer of roughly $500 to $2,000 or more, or 10 to 20 percent of ad spend with a minimum. On a $600-a-month ad budget, a $750 retainer means more than half of every dollar goes to management, not ads.
Is there a minimum to start with Five Minute Ads?
Signing up is free. To launch, you top up a prepaid wallet (minimum $5) that covers the 20% platform fee as your ads spend. Ad spend itself is billed by Meta to your own ad account, so you always see exactly what the ads cost.
