Reddit Ads Cost Calculator
Enter a monthly Reddit Ads budget and see the impressions, clicks, leads and customers it can buy, plus the cost per click, cost per lead and return on ad spend.
Audience presets are starting assumptions inside published 2026 benchmark ranges. Reddit does not publish average CPC or CPM, so replace them with your own campaign numbers once you have them.

In-depth guide: Reddit Ads Cost Calculator
Practical guidance that matches how Reddit communities actually work, written specifically for this tool.
What Reddit Ads actually cost in 2026
Reddit sells ads in an auction. You set a budget and a bid, and the price of each impression or click moves with how many other advertisers want the same audience. That is why you will not find a Reddit price list, and why Reddit's own documentation talks about budgets and objectives rather than average rates.
Third-party benchmarks fill the gap. Published 2026 ranges put most Reddit campaigns at roughly $0.50 to $7 per click and $3.50 to $20 per thousand impressions. B2B and technology audiences sit toward the top of those ranges, typically $1.50 to $3.50 per click and $8 to $15 CPM, because more advertisers compete for engineers, founders and IT buyers. Broad interest targeting is the cheapest way to buy reach; hand-picked subreddits cost more but reach people already discussing your category.
The presets in this calculator use the middle of those ranges. They are there so the tool gives a sensible answer on the first try. Once you have run ads for a week or two, replace them with the CPM and click-through rate from your own Reddit Ads Manager.
How to read the results
- Cost per click is CPM divided by 1,000 times click-through rate. A small change in CTR moves cost per click a lot, which is why creative testing matters more on Reddit than bid tweaks.
- Cost per lead is your monthly budget divided by leads. Compare it with the break-even figure shown under it: customer value multiplied by your lead-to-customer rate.
- Fewer than about 300 clicks a month is too little data to judge a campaign. If the calculator warns you, narrow the campaign to two or three closely related subreddits rather than spreading the budget thin.
- Return on ad spend uses the customer value you entered. If you use lifetime value, remember the revenue arrives over months, not in the month you spend.
How much budget a Reddit Ads test needs
Reddit lets you launch with $5 a day, but that rarely produces enough clicks to learn anything. Reddit's own budget planning guide recommends at least $100 a day for conversion campaigns, and suggests optimising for traffic instead if your budget is nearer $50 a day.
For a B2B lead generation test, a practical starting point is $1,000 to $5,000 a month for 60 to 90 days, concentrated on a few subreddits where your buyers already talk. Use the calculator to check that the budget buys enough clicks to measure, and that the expected cost per lead is below what you can afford.
Ways to lower your Reddit cost per lead
- Match the ad to the subreddit. An ad written like a helpful post in that community earns higher click-through rates, which lowers cost per click at the same CPM.
- Use conversation placements and subreddit targeting for intent, and broad interest targeting only for cheap awareness.
- Send clicks to a page built for Reddit visitors: a clear answer to the problem in the ad, social proof, and one simple next step.
- Retarget visitors who engaged but did not convert. Retargeting audiences usually have higher click-through and lead rates than cold traffic.
- Pair paid campaigns with organic participation in the same subreddits, so people who see your ad also see your team being useful in the comments.
If you want to go one step deeper, pair this with Reddit Engagement Calculator and Subreddit Rules Summarizer. If you'd rather have the strategy executed end-to-end, see Reddit comment marketing service or Managed Reddit aged accounts.
How to use Reddit Ads Cost Calculator (step-by-step)
Use this as a starting point. The best results come from tailoring the final version to subreddit rules and the thread's tone.
- 1
Enter your monthly budget and goal
Type the amount you plan to spend on Reddit Ads in a month and pick whether the campaign is for traffic or for leads. The calculator converts it to a daily budget and warns you if it is below Reddit's minimums.
- 2
Pick an audience preset
Choose broad interest, specific subreddits, B2B and tech subreddits, or retargeting. Each preset fills in a starting CPM and click-through rate that you can overwrite with your own numbers.
- 3
Add your funnel numbers
Enter the share of clicks that become leads, the share of leads that become customers, and what one customer is worth. Use your current website rates if you don't have Reddit data yet.
- 4
Read the results and adjust
Check cost per lead against the break-even figure. If the numbers lose money, try a narrower audience, a better landing page, or a higher-value offer before raising the budget.
When this works best
These are real scenarios where the tool helps you move faster, without sacrificing authenticity.
Sizing a first Reddit Ads test
See how many clicks and leads $1,000 to $5,000 a month can realistically produce before you commit, and whether that is enough data to learn from.
Comparing Reddit with LinkedIn or Google
Put in the same budget and funnel rates you use for other channels to compare cost per lead side by side.
Setting a break-even cost per lead
The calculator shows the highest cost per lead you can afford given your close rate and customer value, so you know when to pause a campaign.
