Residential Improvement Financial Planner

This system is designed to track project costs, manage contractor estimates, and monitor actual expenditures against your initial allocation. It provides a real-time view of your remaining liquidity throughout the project lifecycle. Update this sheet weekly to reconcile invoices and adjust projections as scope changes occur.

Column Definitions

• Item Category: [Text] Broad classification of the work (e.g., HVAC, Structural, Finish).
• Description: [Text] Specific scope of work or itemized purchase.
• Estimated Cost: [Currency] The initial quote or budget allocation.
• Actual Cost: [Currency] The final invoice amount or current spend.
• Variance: [Formula] The difference between estimated and actual costs.
• Status: [Dropdown] Select from: [Not Started], [In Progress], [Deposit Paid], [Paid], [On Hold].

Essential Formulas

Calculate Variance (Column E): Place this in cell E2 and drag down:

=C2-D2

Calculate Total Budget Remaining: Use this to see how much of your total allocation is left:

=SUM(C2:C100) - SUM(D2:D100)

Calculate Percentage of Budget Spent:

=SUM(D2:D100) / SUM(C2:C100)

Conditional Formatting & Data Validation

1. Variance Alert: Apply conditional formatting to the Variance column. Set a rule where cell value is less than 0, format with a light red fill and dark red text to highlight over-budget items.
2. Status Dropdown: Select the Status column and use Data Validation. Choose "List of items" and enter: Not Started, In Progress, Deposit Paid, Paid, On Hold.
3. Completion Highlight: Apply conditional formatting to the entire row where the Status column equals "Paid". Set the format to strike-through text and a light gray background color to visually archive completed work.
