The guide
You choose the budget, and Meta spends it on the impressions or results your ads win. Meta's own pricing page names the main cost factors: ad quality, bidding strategy and performance goal, the type of budget (daily or lifetime) and the campaign objective. Who you target, where the ads appear and the time of year also change what impressions cost.
Meta treats a daily budget as an average. Its pricing page says it may spend up to 75% over the daily budget on some days, and that spend won't be more than seven times the daily budget in a week. A lifetime budget instead sets the total for the whole run.
Link clicks needed = leads wanted ÷ click-to-lead rate
Impressions needed = link clicks ÷ click-through rate
Monthly budget = impressions ÷ 1,000 × CPM
Average daily budget = monthly budget ÷ 30.4With the From leads wanted example numbers, 100 leads at a 10% lead rate need 1,000 link clicks; at a 1% click-through rate that is 100,000 impressions, and at a $10 CPM a budget of $1,000 a month, about $32.89 a day. The same sums work for Instagram ads, which are bought in the same Ads Manager. To check a CPM on its own, use the CPM Calculator.

| Instant form | Landing page | |
|---|---|---|
| Speed | Opens inside Facebook or Instagram, prefilled | Loads your site |
| Lead volume | Often higher, with less effort to submit | Often lower |
| Lead intent | Can be lower; add qualifying questions | Visitors have seen your offer in full |
| Tracking | Leads arrive in Meta or your CRM | Needs the pixel or Conversions API |
Test both if you can, and compare cost per customer rather than cost per lead.

The short answers
You set the budget, and Meta charges for the impressions or results your ads get within it. What a lead costs depends on your audience, offer, creative and form.
One real example: in the period 5 Sep 2025 – 5 Sep 2026, a Schengen visa lead campaign we ran for Easy Travels, a UK travel and visa service, spent £1,964.52 on 337,274 impressions (about £5.82 per 1,000) and brought 612 leads at £3.21 each. Your market will differ.
Impressions = budget ÷ CPM × 1,000. Link clicks = impressions × click-through rate. Leads = clicks × conversion rate. Cost per lead = budget ÷ leads. Small changes in click-through or conversion rate move the cost per lead a lot, which is why creative and the form matter as much as the budget.
In Ads Manager, add the CPM (cost per 1,000 impressions), CTR (link click-through rate) and Results columns. For lead form ads, the conversion rate is leads divided by link clicks.
Questions
It varies by country, audience, season and competition, so there isn't one honest figure. Compare against your own account over time, and judge ads by cost per lead or per customer, not by CPM alone.
Enough for a steady flow of results the system can learn from. Our travel clients' lead campaigns run on £12–£17 a day, which suits their markets; yours may need more or less.
You set the budget on every major platform, so the useful question is what a result costs. Across our client campaigns, the typical average cost per lead is £2.50 to £6.50; our travel clients' Meta lead campaigns run on £12–£17 a day.
They are bought in the same Ads Manager, and Meta can place ads across Facebook, Instagram and its other placements to get results within your budget. Costs differ by placement, which you can see by breaking down results by placement.
Instant forms skip the step of loading a website, which can raise the number of leads, but some of those leads may be less ready to buy. Compare cost per customer, not just cost per lead.
