For a beginner selling online in Bangladesh, a sensible Facebook ad budget is ৳300 to ৳1,000 a day for one Sales campaign, run for at least 5 to 7 days before you judge it. Use the Sales objective (not Boost or Engagement), send people to a landing page, and measure cost per confirmed order, not likes or messages. This guide shows how to set the budget, which objective to choose, and when to scale or stop.
Written by the Sellsull team, October 2026. Ad costs vary by product, season and audience; use these numbers as a starting point and track your own.
Start with the number that matters
Before setting any budget, work out how much you can pay for one order and still make a profit:
Maximum cost per order = selling price − product cost − packaging − delivery you pay − a margin for returns − the profit you want.
Example: you sell a three-piece for ৳1,450. Product cost ৳750, packaging ৳30, delivery subsidy ৳0 (customer pays), returns about ৳70 per order, and you want ৳300 profit. Your maximum ad cost per order is ৳300. If ads bring orders at ৳200, you scale. At ৳450, you fix the ad, the page or the offer, or stop.
How much to spend per day
| Stage | Daily budget | Goal |
|---|---|---|
| First test | ৳300 to ৳500 | See whether people order at all |
| Testing creatives | ৳500 to ৳1,000 | Find the best video or image |
| Scaling a winner | Increase 20% to 30% every 2 to 3 days | More orders at a similar cost |
A useful rule: give each ad set enough budget to get a few orders in a week. If your expected cost per order is ৳250, ৳300 a day gives Facebook room to find buyers. Too small a budget spread over many ad sets learns nothing.
Meta bills in US dollars or taka depending on your ad account. Many Bangladeshi sellers pay with a dual-currency card or through an agency; check the bank charges, since they raise your real cost.
Which objective to choose
- Sales: the right choice for an online store. Facebook shows your ad to people likely to buy, using your Pixel and Conversions API data.
- Messages (Engagement): works if you sell through Messenger, but you have to answer every chat, and many never order.
- Traffic: brings clicks, not buyers. Avoid for selling.
- Boost post: optimises for likes and comments. Fine for awareness, poor for orders.
Sales campaigns need the Facebook Pixel and Conversions API set up, so Facebook learns who buys. On Sellsull both work on paid plans, and you can send the Purchase event only after you confirm an order, so Facebook learns from real buyers, not fake orders. Setup: Pixel and Conversions API guide.
A simple first campaign
- Campaign: Sales objective, one campaign.
- Ad set: Bangladesh (or your delivery area), age range that fits your product, broad interests or none. Advantage+ audience often works well for broad products.
- Budget: ৳300 to ৳500 a day.
- Ads: 3 different creatives: one short video, one carousel, one image. Video usually wins.
- Destination: a landing page for that product, with the price, delivery charge and a COD order form. See how to build a landing page.
Do not change anything for 3 to 4 days. Editing restarts Facebook's learning.
Reading the results
- Cost per purchase is the main number. Compare it with your maximum.
- Click-through rate (CTR) below about 1% usually means the creative is weak.
- Many clicks, few orders: the landing page, price or delivery charge is the problem, not the ad.
- Facebook shows more purchases than you received: common causes and fixes are in why Facebook purchases don't match your orders.
- Confirmed and delivered orders are the real result. If 30% of orders are fake or returned, your real cost per order is much higher.
When to scale and when to stop
- Scale when cost per confirmed order is well below your maximum for 3 or more days. Raise the budget by 20% to 30% at a time, or duplicate the winning ad set.
- Fix when CTR is good but orders are low: improve the page, offer free delivery on 2 items, add reviews.
- Stop an ad that spent twice your maximum cost per order without a sale.
- Refresh creatives every 2 to 3 weeks; the same video gets tired.
Make each order worth more
Raising order value lets you pay more per order and still profit. Use an upsell at checkout, a combo bundle, or a free-delivery threshold. See upsell offers and free delivery rules. Do not forget TikTok, which is often cheaper for video-friendly products: selling from TikTok.
Frequently asked questions
What is the minimum Facebook ad budget in Bangladesh?
Meta allows very small daily budgets, but for selling, ৳300 to ৳500 a day is a practical minimum so the campaign can learn.
How much does one order cost from Facebook ads?
It varies widely by product and creative. Calculate your maximum affordable cost per order first, then judge results against it.
Should I boost posts or run ads from Ads Manager?
Use Ads Manager with the Sales objective for orders. Boosting is optimised for engagement.
How long should I run an ad before deciding?
At least 3 to 4 days without changes, and usually 5 to 7 days before you decide.
Do I need Pixel and Conversions API?
Yes, for Sales campaigns. Without them Facebook cannot learn who buys, and costs go up.
