Having a comfortable 2-story house that suits your needs is a dream come true. However, before construction begins, you need to carefully prepare a 2-story house budget plan. This budget plan is vital to avoid waste and ensure that construction goes according to plan.
Without accurate calculations, the costs can be excessive and disrupt the construction process. Without further ado, let's take a look at how to calculate a complete budget for a 2-story house, with examples in this article!
What Should You Consider When Creating a 2-Story House Budget Plan?
When calculating a 2-story house budget plan, there are several important things you need to consider beforehand. This pre-budget planning process aims to make budgeting more accurate and aligned with construction needs. Here are some considerations to keep in mind before creating a cost estimate for a 2-story house.
1. House Design Plan
Before making a budget plan for a 2-story house, determine the details of your dream house design. This includes specifications such as the number of rooms, the size of each room, and the types of materials to be used.
2. Total Budget
Once the design is clear, the next step is to determine the maximum budget limit from the start. This step enables you to control expenses and avoid unexpected costs that exceed your budget.
3. Details of Costs and Services
In preparing the budget plan for a 2-story house, you need to break down all material and service costs. Material costs include building materials, such as bricks, cement, glass, frames, and others. Meanwhile, service costs include labor costs, such as builders and electricians.
4. Total Costs
Costs per item will be grouped by type of work. The total cost per group will become the final budget for the construction of your 2-story house.

How to Calculate the Budget Plan for a 2-Story House
After considering the points above, the next step is to calculate the budget for a 2-story house. This calculation helps determine the details of the costs required during construction.
This calculation method can also be adjusted for a 6x12 2-story house budget or other sizes. Here are the steps.
1. Compiling Data and Information
The first step in calculating the budget plan is to compile data and information related to the project. The data includes the building area, technical specifications, types of materials, construction methods, material prices, labor costs at the project site, and additional costs, such as equipment rental, transportation, taxes, and administration.
2. List the Tasks
The next step is to make a list of tasks. This list includes stages such as foundation work, structure, walls, roof, flooring, and finishing, which are then broken down into sub-items. For example, foundation work consists of procuring river rocks, cement, sand, and labor.
3. Calculate the Volume of Work
You also need to calculate the volume of each task. Calculations are made for each item, such as the volume of concrete in the structure, floor area, and wall area, in accordance with the technical specifications determined in advance.
4. Calculate Material Requirements and Costs
At this stage, calculate the material requirements based on the volume of work, then multiply the quantity by the unit price to obtain a cost estimate. Next, calculate the estimated labor costs by determining the number of workers, the duration of work, and multiplying by the daily wage.
5. Calculate Other Costs
Do not forget to calculate other costs that may arise during the construction process, such as heavy equipment rental (mixers, scaffolding, etc.), landfill costs, as well as VAT (PPN) and administrative fees in accordance with local regulations, for example, 5% of the total cost.
6. Combine Total Costs
The next step is to add up all the costs of each job and additional costs to get the total project budget. Be sure to double-check to ensure no components are missed and that all calculations are correct.

7. Finalizing the Budget Plan
During the finalization stage, conduct a thorough review to ensure that all data is complete and accurate. Prepare detailed budget plan documentation that includes cost details, work volume, and technical specifications, then submit it for approval or use it as a reference during the project.
8. Adjustments
The final step in preparing a budget for a 2-story house is to make adjustments. These revisions are necessary if there are changes during the project, including adjustments to fluctuations in material prices or labor wages.
Example of a 2-Story House Budget Plan
Here is an example of a 2-story house budget plan for a clearer picture. This table shows various general costs in building a 2-story house, from preparation to finishing. Keep in mind that the figures in this example are only illustrations and must be adjusted to actual conditions, such as material prices and labor wages in your location.
