Interior Design Business Profit Tracker

Interior Design Business Profit Tracker Excel for your interior designers and small design firms — clients and fees, work log, expenses, and a monthly P and L dashboard. Know what every client actually pays — and whether the month actually made money.

Built for interior designers and small design firms who need to know, client by client and hour by hour, what the fee is really worth per hour — without accounting software. If a client is eating hours at a discount rate, this workbook shows it before the next engagement.

WHAT'S INCLUDED (6 sheets):

- Clients & Fees — client, service package, monthly fee, hours per month, effective hourly rate, add-on revenue, and total monthly revenue for every client. Change a fee and the rate and totals update.

- Project Log — date, client, task, hours, hourly rate, amount, and whether it was billable for every job. Retainer rates are pulled from sheet 1 by formula; add-on jobs are priced per job.

- Expenses — software, mileage, office, marketing, insurance, training, other costs, with a monthly cost for each.

- Monthly P and L — revenue, software, mileage, office, marketing, insurance, training, other expenses by month, Jan-Dec, with net profit and margin. Revenue is a formula from the Project Log.

- Dashboard — total revenue, clients, hours, billable vs non-billable hours, capacity used, average rate, expenses, net profit and margin, best and weakest clients, revenue by client, costs by category, and hours by client.

- Cover and How to Use — start here. Yellow cells are the only ones you edit.

HOW IT WORKS:

1. Download the Excel file instantly after purchase.

2. On sheet 1, enter each client's service package, monthly fee, hours per month, and add-on revenue. Effective hourly rate and total monthly revenue fill in by formula.

3. On sheet 2, add a row per job: date, client (spelled exactly as on sheet 1), task, hours, hourly rate, and whether it was billable. Amount fills in by formula. Retainer rows pull the rate from sheet 1.

4. On sheet 3, enter each month's costs by category.

5. On sheet 4, enter expenses each month, then check capacity and net profit on the Dashboard.

HOW THE NUMBERS WORK:

Effective hourly rate is monthly fee divided by hours per month. Total monthly revenue is the fee plus add-on revenue. Average rate per billable hour is total revenue divided by billable hours. Capacity used is hours logged divided by a 160-hour month. Net profit is revenue minus software, mileage, office, marketing, insurance, training, other expenses — before the owner's own pay, which comes out of profit as drawings.

WHO IT'S FOR:

Interior designers, design firm owners, and decorators who want client fees, effective rates, billable hours, capacity, and a monthly P and L in one workbook — without accounting software.

PLEASE NOTE:

- This is a digital download. No physical item will be shipped.

- Works in Microsoft Excel and Google Sheets (upload to Google Drive to open in Sheets).

- Example data for October 2026 is included (12 clients, 125 retainer hours, 143 hours logged in total, 12 expense items). Replace it with your own numbers.

- The example is simplified: net profit is before the owner's own pay — the owner takes drawings from profit, so add an owner-pay line on the P and L if you draw a salary. Capacity is measured against a 160-hour month; change it on the Dashboard if your month is different.
