The choice of Software Development Life Cycle (SDLC) model significantly impacts project planning in several ways:

1. **Project Timeline**: Different SDLC models have different timelines. For example, the Waterfall model follows a linear sequence and each phase must be completed before the next begins, which can be time-consuming. On the other hand, the Agile model allows for simultaneous work on different phases, which can speed up the development process.

2. **Resource Allocation**: The choice of SDLC model determines how resources are allocated throughout the project. In the Waterfall model, resources are allocated at the beginning of the project and remain constant. In the Agile model, resources can be adjusted throughout the project based on changing requirements.

3. **Risk Management**: Some SDLC models, like the Spiral model, have built-in processes for risk management. Choosing such a model can help in better planning and mitigation of potential risks.

4. **Feedback and Changes**: SDLC models like Agile and Iterative allow for regular feedback and changes in the project. This can impact the planning as it requires a flexible approach where plans can be adjusted based on the feedback received.

5. **Project Complexity**: The complexity of the project also determines the choice of the SDLC model. For complex projects, models like Spiral or Incremental are more suitable as they allow for more detailed planning and development.

6. **Customer Involvement**: If the project requires frequent customer involvement and feedback, models like Agile or RAD (Rapid Application Development) are more suitable. This impacts the planning as regular meetings and discussions with the customer need to be scheduled.

In conclusion, the choice of SDLC model can significantly impact the planning of a project in terms of timeline, resource allocation, risk management, feedback incorporation, handling project complexity, and customer involvement.
