Reddit ads cost calculator
Put in a budget and the rates from your campaign. See the impressions, clicks and cost per sign-up they work out to.
Work it out
Reddit doesn't publish average costs. Use the rates from your own campaign, or the estimate Reddit's Ads Manager shows when you set one up.
What Reddit says about cost
- The daily budget is at least $5.
- Your ad group may overspend its budget by up to 20%, because ads are sold in live auctions.
- Spending the whole budget isn't guaranteed. An ad that wins few auctions spends less.
- Lowest cost is the default bidding. You set no bid and Reddit gets as many results as it can for the budget. Cost cap and target cost hold the average cost down instead, and may leave budget unspent.
- Budget changes can take up to 60 minutes to take effect.
Reddit publishes no average CPM or cost per click, so this page doesn't make one up. Your own campaign's numbers are the only ones that fit your ad and your audience.
What you pay for
| Objective | You pay for |
|---|---|
| Awareness and consideration | Impressions (CPM), or video views (CPV) for video goals |
| Traffic | Clicks (CPC), or impressions (CPM) when optimizing for landing page visits. Reddit's “Budgets and Bidding” page says instead that lowest cost bills impressions (oCPM) and cost cap bills clicks (CPC). |
| Sales | Optimized impressions (oCPM) with lowest cost or target cost; clicks (CPC) with cost cap |
| Lead generation | Optimized impressions (oCPM) with lowest cost or target cost; clicks (CPC) with cost cap |
| App promotion | Optimized impressions (oCPM) with lowest cost or target cost; clicks (CPC) with cost cap |
Reddit says cost cap goes away for sales, lead and app campaigns on February 10, 2027.
Questions people ask
- How much do Reddit ads cost?
- As much as you set. The daily budget must be $5 or more (Reddit Ads Help), and what each impression or click costs comes from a live auction, so it depends on your targeting, your bid and your ad. Reddit doesn't publish average costs.
- What is the minimum budget for Reddit ads?
- $5 a day. Reddit also says your ad group may overspend its budget by up to 20%, because ads are sold in live auctions (Reddit Ads Help).
- Do I pay per click or per impression on Reddit?
- It depends on the campaign objective and bidding. Awareness campaigns pay for impressions. Sales, lead and app campaigns pay for optimized impressions unless you choose a cost cap, which bills per click. For traffic campaigns Reddit's two pages differ: Campaign Objectives says clicks, while Budgets and Bidding says impressions with lowest cost and clicks with a cost cap. Ads Manager shows which applies when you set one up.
- Where do I find my CPM or cost per click?
- In Reddit's Ads Manager: it shows an estimate while you set up a campaign, and the real figures in your reports once ads run. Put those here to see what a bigger or smaller budget would buy.
- Why didn't my campaign spend its whole budget?
- Reddit doesn't guarantee it will. If your ad wins few auctions, or your cost cap or target is too tight, the ad group spends less than its budget (Reddit Ads Help).
- Is what I type saved or sent anywhere?
- No. The math runs in your browser. The numbers sit in the page's address only so you can copy a link to them.
