A few years ago, I was just like you are now, depositing 100k into my account, excitedly running Google ads and wondering why I didn't get a call all day. The core issue is not how much Google Ads costs per day, but how that money is spent to make a profit. In fact, to get started and really "see results", you should think about a figure of 300,000 - 500,000 VND/day. But this is just the tip of the iceberg, the much more important part will determine whether you are successful or are throwing money out the window.
So in the end, what is the minimum daily Google Ads budget to "have a story"?
The minimum budget for running Google Ads per day should range from 300,000 - 500,000 VND so that Google's machine learning system has enough distribution data and brings actual conversions.
With more than 10 years of experience at Pham Hai, I realize that there are no rigid regulations from Google forcing you to deposit how much. However, if you ask how much does it cost to run Google Ads a day at least so as not to be "sunk" among competitors, then the number 300k - 500k is a safe starting level. This daily budget is enough for your ads to show regularly and collect data. If you calculate mentally, how much is the Google Ads budget per month for this level will be about 9 to 15 million VND.
Talking numbers: Reference minimum budget for a few popular industries
Each industry will have a different level of competition, leading to Google Ads costs by industry also varying greatly.
Below is the average CPC (Cost Per Click) price in the Vietnamese market, updated with the latest update in 2026 that I have compiled:
| Product industry | Average CPC (VND) | Proposal date budget (VND) |
|---|---|---|
| Real estate | 20,000 – 100,000 | > 1,000,000 |
| Finance, Insurance | 30,000 – 80,000 | 800,000 - 1,500,000 |
| Education, Courses | 15,000 – 50,000 | 500,000 - 1,000,000 |
| Retail, Fashion | 3,000 – 15,000 | 300,000 - 500,000 |
As you can see, if you sell clothes, 300k/day is enough to live a healthy life. But if selling a villa, 300k may only be enough for 3-4 mouse clicks. To know exactly how much money your industry needs, Detailed keyword research is an extremely important first step that cannot be overlooked.
"Spark" budget (300,000 VND/day): Who is it for and what can it do?
The budget of 300,000 VND/day is especially suitable for small businesses (SMBs) who want to test the market or are new to running advertising.
Many people often ask me should I run Google Ads with a low budget? The answer is YES, as long as you know how to target narrowly. With this amount of money, don't be greedy and run nationwide or use keywords that are too short. Focus on a small niche, a specific geographical area to optimize sales. If you're new, read Google Ads instructions for running ads from scratch to learn how to set up campaigns correctly and avoid wasting money in vain.
"War" budget (>500,000 VND/day): When do you need to be more aggressive?
When you are in a highly competitive industry or want to quickly breakthrough advertising effectiveness, a budget of over 500,000 VND/day is required.
At this point, the question is no longer about saving, but about how much Google Ads budget to have regular orders. When your competitors are spending millions every day, a larger budget helps you maintain top visibility. It also helps Google's Smart Bidding system learn faster, thereby bringing in more potential customers.
7 "hidden" factors that determine whether your advertising costs are expensive or cheap (not Google)
Các yếu tố ảnh hưởng đến chi phí quảng cáo Google Ads bao gồm: giá thầu, điểm chất lượng, mức độ cạnh tranh, đối tượng mục tiêu, trang đích, mạng quảng cáo và tỷ lệ click ảo.
Many people mistakenly believe that Google prices everything itself. In fact, whether the cost is expensive or cheap depends on how you optimize the campaign. At Pham Hai, I always remind the team to tightly control these 7 "hidden" factors.
Keyword bidding (CPC): The never-ending battle and how to avoid being the highest bidder
The bid (CPC) is the maximum amount you are willing to pay for a click, but the highest bidder may not be shown first.
Many of you wonder how much does Google Ads cost per click? It depends entirely on how aggressively you and your competitors are bidding on that keyword. However, Google doesn't just look at your wallet. If you know how to optimize, you can absolutely pay CPC lower than your competitors and still stay in the top 1 position.
Quality Score: Google's "darling" and the Ad Rank formula = Bid x Quality Score
Điểm chất lượng (Quality Score) càng cao, chi phí bạn phải trả cho mỗi click càng rẻ, đây là nguyên lý bất di bất dịch của Google Adwords.
Quality Score is rated from 1 to 10 based on three factors: expected click-through rate (CTR), ad relevance, and landing page experience. Google wants users to have the best experience. Therefore, if your ad is useful, Google will "reward" you by lowering your actual bid.
Industry competition level: Why is running ads for real estate more expensive than drain cleaning services?
The higher the industry's profit per order, the fiercer the competition, causing advertising costs to skyrocket.
A real estate contract can bring in billions, so trading floors are willing to pay 100,000 VND for a click. On the contrary, drain cleaning services have a lower profit margin and the click price will also be softer. Understanding your industry helps you avoid heat stroke when looking at the budget report.
Target audience: The more precise the target, the cheaper the cost
Narrowing down the right target audience helps you thoroughly eliminate junk clicks, thereby effectively protecting your daily budget.
You sell maternity dresses but show your ads to men aged 18-24? That's the fastest way to burn money. Careful analysis of demographics, interests and search behavior will help every dollar you spend reach the right people who are in need of a purchase.
Landing page and ad copy: A bad landing page is the most effective money-burning machine
A slow-loading Landing page or an incorrectly written ad copy will seriously reduce conversions, causing CPA costs to skyrocket.
Customers click on the ad (you lose money) but when they go to the website and see a bad interface and ambiguous information, they will leave immediately. At this point, even if you attract thousands of traffic, your revenue will still be 0. Optimize page loading speed and write convincing content.
The advertising network you choose: Search and Display (GDN) are worlds apart in terms of cost
Mạng tìm kiếm (Search) thường có giá click đắt nhưng tỷ lệ chốt đơn cao, trong khi Mạng hiển thị (GDN) tính phí theo CPM lại rất rẻ, hợp để làm thương hiệu.
Search ads target people who are actively looking to buy a product. And GDN follows users when they read newspapers and watch videos. Depending on your goals, you allocate your budget appropriately. In addition, for those who sell physical products, setting up Google Shopping Ads for effective online sales is an extremely intuitive strategy for displaying product images and generating good orders.
Virtual click: The archenemy and how to avoid it
Click ảo từ đối thủ cạnh tranh hoặc các phần mềm bot tự động có thể ngốn sạch ngân sách của bạn chỉ trong vài giờ.
This is a headache in Vietnam. To prevent this, you should use third-party clickjacking blocking tools, exclude suspicious IP ranges, or set up a custom audience file. Don't let your hard-earned money fall into the hands of bad players.
Effective 3-step formula for calculating daily Google Ads costs for newbies
Cách tính chi phí Google Ads hàng ngày hiệu quả nhất là dựa trên mục tiêu CPA, tỷ lệ chuyển đổi của website và số lượng khách hàng bạn mong muốn đạt được.
Don't judge your budget based on your emotions. As a marketer, everything needs to be based on specific numbers. Take out a pen and paper and calculate with us in these 3 extremely simple steps.
Step 1: Determine target CPA (How much are you willing to pay to have 1 customer?)
CPA (Cost Per Action) mục tiêu là số tiền tối đa bạn chấp nhận chi trả cho quảng cáo để thu về một đơn hàng hoặc một data khách hàng.
For example, you sell a pair of shoes for a profit of 300,000 VND. You decide to spend 30% of your profits on marketing. So your target CPA is 100,000 VND. If the cost to have an order exceeds 100k, you are losing money and need to optimize immediately.
Step 2: Estimate the conversion rate of the website
Conversion rate shows how many of every 100 people who click on your ad and visit your website actually make a purchase.
On average in Vietnam, this number ranges from 2% - 5% depending on the industry. If your conversion rate is 2%, that means you need 50 clicks to get 1 sale. From here, you can easily work out the maximum CPC price you can pay.
Step 3: Create the formula: Daily budget = (Number of target customers x CPA) / Number of days in the month
Applying this formula, you will create a clear financial plan, ensuring ROI (return on capital) is always positive.
Let's say this month you want 150 orders from Google Ads. Your target CPA is 100,000 VND/application.
- Total monthly budget = 150 x 100,000 = 15,000,000 VND.
- Daily budget = 15,000,000 / 30 days = 500,000 VND/day. It's simple, isn't it?
Should I run Google Ads myself or hire an agency? Actual cost and efficiency problems
Whether you should run Google Ads yourself or hire an agency depends entirely on the size of your budget, time resources and professional experience of the internal team.
This is a crossroads that every business owner must face. Running it yourself is afraid of making mistakes, outsourcing costs money on service fees. Let me clearly analyze the pros and cons so you can easily make a decision.
When you SHOULD run your own: Save on management fees, be flexible, but at the cost of time and mistakes
If your budget is under 15 million/month and you have free time to learn, running on your own is a wise choice to understand the market.
You will save 15-20% on management fees. You can also proactively change messages and bids at any time. However, the biggest risk is that you will have to use your own money to "pay tuition" for technical mistakes in the early stages.
When do you NEED to hire an Agency: Save time, have expertise, optimize better but incur service fees
When the budget is large and the industry is fiercely competitive, using Google Ads running service from a reputable Agency will help you optimize ROAS most effectively.
The agency has a team of experts who eat and sleep with Ads every day. They have the tools, experience in handling locked accounts and know how to get through the narrow gaps of the market. You pay a service fee, but in return you have peace of mind and time to focus on the core work of closing sales and customer care.
Should you run Google Ads with a low budget? Optimal tips for small businesses
Running Google Ads with a low budget is completely feasible, this is the way to optimize Google Ads costs for small businesses if you know how to apply guerrilla tactics.
If we don't have much money, we have to use our brains more. Don't go head-to-head with the big guys who are spending money running extensive advertising. Immediately apply the 4 practical tips below to save every penny of your budget.
Focus on "long-tail" keywords
Long-tail keywords (e.g. "buy men's size 42 black running shoes") have cheaper bids and many times higher conversion rates than short keywords ("men's shoes").
Although the search volume of these keywords is low, people who type them have an extremely strong need to buy. Collecting dozens of long-tail keywords will bring you a number of quality customers at a very low cost.
Conversion optimization (CRO) instead of just focusing on clicks
Instead of spending more money to attract traffic, optimize the experience on the website to convince those who click to definitely leave information.
Make the call button more prominent, simplify the registration form, and add real feedback from old customers. When your conversion rate increases from 2% to 4%, you halve your cost per order without increasing your advertising budget.
Use a smart bidding strategy (Smart Bidding)
Smart Bidding uses Google's AI to automatically adjust bids in real-time, keeping you close to your CPA or ROAS goals.
In 2026, Google's AI is already extremely smart. Instead of manually monitoring each dollar's bid, provide enough conversion data and leave bid optimization to the system. It analyzes millions of user signals much faster than humans.
Take advantage of remarketing lists to "reacquire" old customers
Remarketing helps your ads pursue people who have visited your website but have not yet made a purchase, at a much cheaper cost than finding new customers.
Customers rarely buy on the first visit. They also have to compare prices and ask their spouses' opinions. Re-displaying a 10% discount banner right when they are wondering will be the perfect deal, helping to maximize revenue for the business.
In short, don't ask how much does Google Ads cost per day anymore. Ask how your 300,000 VND per day is more effective than your competitors who are spending 1,000,000 VND. The key lies in continuously optimizing your Quality Score, focusing on conversions, and understanding your customers. Start small, measure carefully, and you'll find the number that works best for your business.
