What the Home Decor Project Planner actually calculates
For durations below three weeks, design takes 20 percent and procurement 30 percent as fractional weeks. For longer targets those shares are rounded with a one-week minimum each; installation receives the remainder. Scope adds a coordination checkpoint rather than increasing available time. DIY share divides the budget, not tasks or hours. The schedule is a proposed allocation and does not verify supplier lead times.
The calculation path
The planner assigns ordered phases within the target duration, using fractional weeks below three weeks, and separates DIY from professional work.
Inputs that can change the answer
- Project scope: Select the applicable project scope from the listed choices.
- Project budget: Enter project budget in the selected currency; keep tax and included work consistent.
- Target duration: Target duration in whole weeks; this is your allowance, not a predicted delivery schedule.
- DIY share: Percentage of the budget assigned to DIY spending, not the percentage of tasks or hours.
- Currency: Label for all entered prices; no currency conversion is performed.
Checks that stay outside the formula
Place long-lead orders only after final measurements and approved samples.
A practical order for entering the data
- Select the project scope and enter budget and target duration in whole weeks.
- Enter a whole-number DIY share between zero and 100 percent.
- Compare the phase durations with supplier lead times and replace the simple budget split with task-based trade quotes before scheduling work.

Planning example: project scope = Single room refresh, project budget = 8000, target duration = 8, diy share = 30 % and currency = USD ($). These sample choices show the rule path only; use the options that reflect the room and priorities you actually have.
