Ad Management Cost Calculator
Compare what it really costs to get your ads run three ways — doing it yourself, hiring an agency, or using software — including the number nobody publishes: each option as a percentage of your ad spend.
This is the interactive companion to DIY vs agency vs AI ad management: what each really costs.
Inputs
What actually goes to Google and Meta each month, before any fees.
Building, checking, and adjusting campaigns yourself. Include the reporting.
Your billable rate, or what you would earn doing your actual job instead. Use 0 if the hours have no alternative use.
Flat monthly fee from their quote. Enter 0 if they only charge a percentage.
Management fee charged on top of spend, entered as a percentage. Enter 0 if they only charge a retainer.
Defaults are illustrative placeholders, not benchmarks or averages. Replace them with your own numbers and the agency quote in front of you.
Cost to get the ads run
Do it yourself
$900
Opportunity cost
12 hrs × $75/hr
36.0% of ad spend
No invoice arrives, but the hours come out of work you would otherwise be paid for.
Agency
$1,375
Retainer + % of spend
$1,000 + 15.0% of $2,500
55.0% of ad spend
The percentage component grows every time you increase budget, whether or not the work grows with it.
Software (AdFlint)
$89
Flat monthly plan
Growth plan — $89/mo, 0% markup on spend
3.6% of ad spend
Self-serve plans are a flat fee with 0% markup on ad spend. You still make the calls.
| Line | Do it yourself | Agency | Software (AdFlint) |
|---|---|---|---|
| Management cost | $900 | $1,375 | $89 |
| As % of ad spend | 36.0% | 55.0% | 3.6% |
| Ad spend | $2,500 | $2,500 | $2,500 |
| All-in monthly | $3,400 | $3,875 | $2,589 |
All-in monthly is ad spend plus that column’s management cost. For the DIY column the total includes your time, which is a real cost but not a cash payment — the money leaving the bank is the ad spend on its own.
Reading this honestly
- The DIY column is a real cost even though nobody invoices you for it. If your hour is worth nothing to the business, set the rate to 0 and the column goes to zero with it.
- At higher spend, an agency’s strategy, creative production, offer testing, and account management can be worth more than the fee gap. This tool prices the fee, not the quality of the thinking, and it cannot tell you whether a specific agency closes that gap.
- The software column assumes you still make the decisions, approve the creative, and spend some time in the account. It is cheaper because it is a different trade, not because the work disappears.
- AdFlint self-serve plans are a flat fee with 0% markup on ad spend — your card pays Google and Meta directly. The separate Managed done-for-you tier is priced differently ($249/mo floor plus a share of managed spend, metered and provisioned by an operator) and is not what this column shows.
Three costs, one comparison
Every route to running ads has a management cost. Two of them just hide it better than the third.
DIY has a price tag too
Hours × what your hour is worth is the cost of doing it yourself. No invoice arrives, but the time comes out of billable or revenue-generating work.
Agency = retainer + % of spend
Many agencies charge both. The retainer is fixed, the percentage scales with budget, and the two together are what you should compare.
Software is a flat fee
AdFlint self-serve plans are a flat monthly fee with 0% markup on ad spend — your card pays Google and Meta directly.
Fee as a % of spend is the real number
A $1,000 retainer is 40% of a $2,500 budget and 3.3% of a $30,000 one. Same fee, completely different decision.
How to compare fees without fooling yourself
Most cost comparisons stop at the invoice, which is why DIY always looks free and agencies always look expensive. The honest version prices your hours, prices the agency’s full quote — retainer and percentage together — and then divides each one by ad spend. At a small budget, a percentage-of-spend fee looks harmless and a retainer looks brutal. At a large budget, the two swap places.
Worked through with the tool’s illustrative defaults: at $2,500/mo of ad spend, 12 hours a month at $75 an hour is $900 of your time, or 36% of spend. An agency charging a $1,000 retainer plus 15% of spend costs $1,000 + $375 = $1,375, or 55% of spend. AdFlint’s Growth plan covers ad spend up to $2,500 at $89/mo, which is 3.6% of spend. Those are your inputs, not benchmarks — change any of them and every percentage moves.
Be fair to the agency column as well. At higher spend, the work you are buying is often strategy, creative, and offer testing rather than button-pressing, and that work can be worth more than the fee gap. What this calculator can tell you is the size of the gap. What it cannot tell you is whether a specific agency closes it. If you want to know what a retainer typically includes, read what a PPC retainer actually buys, then compare it against AI ad tool pricing.
The software column assumes something specific: you still make the decisions, approve the creative, and own the strategy. It is a cheaper trade, not a free one. If you are still deciding how much to spend before comparing who should run it, start with the ad budget calculator and Google or Meta first, by budget.
What the software column buys you
AdFlint builds, launches, and monitors Google and Meta campaigns on a flat monthly plan chosen by your ad spend, then shifts budget toward what is working. Self-serve plans carry 0% markup on ad spend — your card pays the platforms directly, and you keep the accounts. The separate Managed done-for-you tier is priced differently and provisioned by an operator.
Keep going
Once you know what management costs, check whether the ads themselves pay for it. Run your numbers through the ROAS calculator, the CPA calculator, and the CAC and LTV calculator — management fees only make sense against the profit the account produces.

Questions
How much does ad management actually cost?
It depends on which of three costs you are paying. Doing it yourself costs hours multiplied by what your time is worth. An agency typically costs a monthly retainer, a percentage of ad spend, or both — use the quote in front of you rather than an average. Software costs a flat subscription. This calculator puts all three on the same line so you can compare the fee, the all-in monthly total, and the fee as a percentage of ad spend.
Is my own time really a cost?
Yes, if the hours would otherwise go to paid or revenue-generating work. That is the standard opportunity-cost view: ten hours a month at a $75 billable rate is $750 of work you did not do. If your hours genuinely have no alternative use, set your hourly value to 0 and the DIY column drops to zero — the tool does not force the assumption on you.
Why show cost as a percentage of ad spend?
Because it is the comparison that decides the answer, and almost nobody publishes it. A fee only means something relative to the budget it manages. The percentage view also makes the shape of each model obvious: DIY and flat-fee software fall as a share of spend when you scale, while a percentage-of-spend agency fee stays constant no matter how much extra work the larger budget actually creates.
When is an agency worth the higher fee?
When the work you are buying goes beyond running campaigns. At higher spend levels, strategy, creative production, offer testing, landing pages, and dedicated account management can produce more value than the fee difference. This calculator prices fees, not judgment. If an agency reliably improves results by more than the gap it charges, the gap is worth paying.
Which AdFlint plan applies to my ad spend?
Plans are picked by monthly ad spend: Starter $10 up to $100/mo, Launch $40 up to $1,000, Growth $89 up to $2,500, Scale $109 up to $5,000, Accelerate $119 up to $10,000, Performance $219 up to $20,000, and Premium $319 up to $30,000. Above $30,000/mo pricing is custom, so the calculator shows Custom rather than guessing. There is a 7-day free trial.
Does AdFlint take a percentage of my ad spend?
Not on the self-serve plans. Those are a flat monthly fee with 0% markup, and your own card pays Google and Meta directly. The separate Managed done-for-you tier is priced differently — a $249/mo floor plus a share of managed spend, metered and provisioned by an operator — so the 0% markup statement applies to self-serve plans only.
