Cooking at Home vs. Buying Food: Which Is Cheaper? 5 Factors to Consider
The Eternal Debate: Is Cooking Always Cheaper?
Many parents or traditional financial experts often give one-sided advice: “If you want to be wealthy, stop eating out and start cooking.” However, for young urbanites living in big cities with high mobility, this advice often feels irrelevant or difficult to apply. Let’s break down the myths and realities behind the cooking vs buying food debate to see which strategy actually saves you more money.
The ‘Cooking is Always Cheaper’ Myth
Cooking for yourself can become very expensive if you don’t have a clear shopping plan. Imagine you want to cook a specific menu, like Seafood Capcay. You have to buy oyster sauce, fish sauce, sesame oil, cornstarch, shrimp, squid, and various vegetables. If those seasonings are only used once and then expire in the corner of your fridge, the cost per serving of your food will be much higher than buying a portion of Capcay at a nearby street stall. This is why in weighing the pros and cons of cooking vs buying food, ingredient efficiency is the main key.

Forgotten Variables: Time and Energy
In economics, there’s a term called opportunity cost. If you spend 2 hours every day shopping, washing vegetables, cooking, and washing dishes, ask yourself: What is the value of your time? For a freelancer paid by the hour or an employee who needs more rest to stay productive, those 2 hours have a nominal value. When analyzing cooking vs buying food, you must account for these hidden labor costs.
If that time could be used to work on a side hustle that generates money, or simply to rest to avoid burnout, then buying food might be a more logical option. However, for those of you currently following budgeting tips for students, cooking can be an activity that significantly helps suppress spending if done with the right techniques, such as batch cooking or healthy meal prep.

Is it Cheaper to Cook or Buy Food? Check the Comparison Table
To make it easier for you to decide on your cooking vs buying food strategy, let’s look at the comparison between cooking for one week (21 meals) versus consistently buying food outside. These figures are average estimates in big cities for one person.
| Criteria | Cooking (Saving Mode) | Buying (Local Canteen) | Buying (Apps/Online) |
|---|---|---|---|
| Ingredients/Menu | $25 – $35 | $45 – $60 | $85 – $130 |
| Additional Costs | Gas, Elec, Water, Soap (~$5) | Transport/Parking (~$2) | Delivery, Service, Small Order Fee |
| Time Investment | 10-15 Hours/Week | 3-5 Hours/Week | < 1 Hour/Week |
| Nutritional Quality | Controlled (Healthier) | Varied (Often Oily) | Varied (High Salt/Sugar) |
Equipment Investment (Stove, Fridge, Rice Cooker)
One factor often ignored when comparing cooking vs buying food is the initial cost or capital expenditure. If you start from scratch, you need to buy a gas stove, pots/pans, and a rice cooker. This initial investment can be significant.
If you only plan to stay in a temporary residence for 3 months, the cost of these tools, when divided per month, will significantly increase your expenses. However, if used long-term (over 1 year), the equipment cost will depreciate and become very small per portion. For beginners, following a budget food prep tutorial can help optimize the use of minimal existing tools.
Portion Flexibility and Nutritional Variety
The main advantage of cooking for yourself is full control. You can adjust how much protein goes in, the type of oil used, and the hygiene of the ingredients. In the long run, this isn’t just about saving money, but saving on hospital bills. Buying food outside is indeed more practical, but we often have no control over excessive sodium or the cleanliness of the ingredients. So, in the context of cooking vs buying food, consider long-term health value as well.
Realistic Scenario: Budget of $5 a Day, What Can You Eat?
Let’s do a real-life simulation. Say you have a food allowance of $5 per day. How does the final result differ between the three options in the cooking vs buying food dilemma?
Option A: Grocery Shopping (Cook 3 Portions)
With $5 at a local market, you can buy staples like rice, eggs, seasonal vegetables, and a small portion of protein.
The Result: You can eat 3 times a day with simple, nutritious meals. In this scenario, the answer to the cooking vs buying food question is that cooking wins by a landslide in terms of quantity and nutrition.
Option B: Local Canteen (Direct Purchase)
At a regular food stall, $5 might only be enough for 1-2 meals with a standard menu. You don’t need to wash dishes or bother going to the market, but portions are limited and variety depends on what’s available that day.
Option C: App Delivery
Let’s be honest, $5 on a delivery app can almost never give you 3 meals. After adding delivery and service fees, a single meal can often exceed your entire daily budget. Here, the comparison of cooking vs buying food makes it very clear that delivery is the most wasteful option if done every day.
3 Fatal Mistakes that Make Cooking More Expensive
If you’ve tried cooking but feel like your money is disappearing fast, you might be trapped in one of the following mistakes. Understanding these errors is crucial in evaluating cooking vs buying food for your personal case.
1. Impulsive Grocery Shopping
The number one mistake when going to the supermarket is shopping while hungry or without a list. If you aren’t disciplined, your bill could soar higher than if you ate at a local stall every day. Remember, the essence of cooking vs buying food is control over what you actually need, not what you want in the moment. Check out our tips on saving money on groceries for better results.
2. Rotten Food Due to Failed Food Prep
Many people have good intentions but end up ordering food via apps due to exhaustion. By the end of the week, the groceries have spoiled. This is a double waste. Without good stock management, the cooking vs buying food debate will always be won by the eating-out option because no ingredients are wasted.
3. Too Ambitious with Complex Recipes
Don’t get trapped in the trend of cooking fancy meals every day. If a recipe requires 10 types of spices you’ve never owned, it becomes an unnecessary expense. For beginners, focus on basic dishes with common seasonings. Consistency in simplicity is the key to a winning cooking vs buying food strategy.
Decision Checklist: When to Cook and When to Buy?
There is no one-size-fits-all rule. You need to evaluate your situation using the following checklist to determine which cooking vs buying food approach is more economical for you:
- Number of People: Cooking for a family is much more efficient than cooking for one.
- Location Access: If you have to spend significant money on transport just to get to a market, buying food nearby might make more sense.
- Equipment Availability: If you don’t have a fridge, don’t force yourself to buy ingredients in bulk.
- Free Time vs. Deadlines: During busy weeks, your mental health is worth more than a small saving per meal.
- Skill Level: If you often fail at cooking, the cost of failure must be calculated. Start slowly.
In the long run, understanding the benefits of recording daily finances will give you real data on which pattern best suits your lifestyle. Data never lies, and by recording, you will see the results of the cooking vs buying food comparison in your wallet.

Frequently Asked Questions (FAQ) on Budget Eating
Does food prep really save money?
Absolutely! Food prep helps you buy ingredients in bulk which is usually cheaper, and ensures no ingredients are wasted.
How can I save if I have no time to cook at all?
Focus on a “Smart Buying” strategy. Avoid delivery apps and walk to the nearest stall. Also, buy large portions that can be split into two meals and use your own rice cooker.
Is it better to buy rice in bulk?
For one person, a small sack (5kg) is usually ideal. It’s cheaper than buying by the liter but small enough to stay fresh.
What are the signs that my food spending is unhealthy?
If your food expenses exceed 30-40% of your total income, that’s a red alert. Use MoneyKu to monitor this percentage automatically every month.
Conclusion
So, when looking at cooking vs buying food, which is better? Cooking for yourself is almost always cheaper in nominal terms, provided you have a plan and stay disciplined. However, buying food can be a strategically cheaper choice if the time you save can be used to increase your income or maintain your productivity.
The best step is to combine the two. Perhaps you can cook on weekdays and give yourself a reward to eat out on weekends. Whatever your choice, make sure every dollar that goes out is well-recorded so you remain in full control of your financial future. Good luck, and may your wallet stay healthy!
