Construction Cost Calculator

	Cost-Plus	Lumpsum / Fixed-Price
Money Safety	Clients will be making the payments only after they receive the material to their site and the specific work is compled. So, here the client's money will be safe with them and they can pay only when required.	Clients will be required to make bulk advance payments upfront, irrespective of the progress or completion of specific work, posing a potential risk to their funds without a guarantee of receiving materials or completed work.
Cost saving	Cleints will be saving upto 10% of the overall project cost since the payments will be made directly to the vendors.	No option to save as the project cost is Fixed and Clients have to pay the agreed amount to the contractor.
High Quality	Contractor prioritize quality over cost-cutting since their profit isn't directly tied to minimizing expenses, potentially leading to a higher standard of workmanship and usage of quality Materials.	Here, Contractors prioritize cost-cutting over quality, as their profit is directly tied to minimizing expenses, potentially leading to a lower standard of workmanship and usage of subpar materials
Client Satisfaction	With the ability to adjust project details as they needed, Clients are more likely to be satisfied with the final result.	Due to the inability to modify project details as required, Clients may not be satisfied with the final result, as they have limited flexibility during the construction process.
Transparency	Cost-plus contracts provide transparent pricing with full client visibility into project costs, including materials, labor, contractor fee, and design costs. Detailed cost breakdowns ensure transparency, allowing informed decisions without surprises or hidden expenses.	Lack of transparency in pricing, as clients may not have full visibility into the project's costs, including detailed breakdowns of materials, labor, contractor fees, and design costs. This limited transparency may lead to uncertainties, potential surprises, and hidden costs, making it challenging for clients to make decisions.
Flexibility	Cost-plus facilitate adjustments and customizations without the need for extensive negotiation. This is particularly advantageous for projects requiring customization, as clients have the flexibility to modify project details, materials, and features as the project progresses, accommodating their evolving preferences.	Lack of flexibility can be a limitation for projects that require customization, as clients may face challenges in modifying project details, materials, and features during the course of the project, limiting their ability to accommodate evolving preferences.
Control over Project	Cost-plus model provides improved project control, empowering clients with active involvement in decision-making processes for every aspect of their project. This enhances their ability to influence and oversee the desired outcomes.	Fixed-price models limit client control over project decisions, restricting their involvement in decision-making processes for various aspects of their project. This constrains their ability to influence and oversee outcomes, reducing the level of empowerment in project.
Project Time-line	In a cost-plus, projects often experience expedited progress due to the flexible nature of the contract. With the ability to make swift decisions and adjustments, clients and contractors collaborate seamlessly, promoting efficiency and ensuring timely completion.	Projects may encounter slower progress due to the rigid nature of the agreement. Limited flexibility in decision-making and adjustments can lead to potential delays, as clients and contractors face challenges in adapting to changing circumstances, potentially impacting efficiency and the timely completion of the project.
Value Engineering	In cost-plus, contractors are free from the constraints of a fixed budget, fostering a willingness to propose innovative ideas. Unlike fixed-price contracts, this approach allows for greater flexibility and encourages creative solutions. The absence of budget restrictions enables a more dynamic and open approach to project execution.	In fixed-price contracts, the predetermined budget restricts contractors from proposing innovative ideas, in contrast to the flexibility allowed by cost-plus models. The rigidity of fixed budgets can discourage creative solutions and hinder a dynamic approach to project execution.
Manpower	Contractors can strategically allocate skilled manpower, prioritizing the delivery of high-quality work. This approach allows for a focus on expertise and professionalism, enhancing the overall quality of the project.	With the constraint of cost minimization, contractors may struggle to strategically allocate skilled manpower, compromising the prioritization of high-quality work. This could impact the overall project quality by limiting the focus on expertise and professionalism.
