Apartment Finishing Cost: How to Plan Your Budget Without Surprises
The cost of finishing an apartment is the first question on the mind of anyone who received their apartment at the plaster stage — and the main worry isn't the number itself, but the surprises that appear mid-work and break the budget. In this guide you'll learn how to plan a realistic finishing budget, what items to include, and how to avoid the expenses you didn't see coming.
Apartment finishing cost in short
The total cost = the sum of each item's cost (plaster, flooring, paint, electrical, plumbing, doors, kitchen, bathrooms) according to the finishing level and materials you choose. There's no fixed number for everyone — but there is a planning method that gets you to a realistic estimate and protects you from surprises.
Apartment finishing cost items
To make a realistic budget, you must account for all these items, not just some:
Core works: plaster, and electrical and plumbing rough-in.
Floors and walls: ceramic, porcelain, marble, or parquet.
Paint and gypsum: paint, gypsum works, and decor.
Doors and windows: by type and material.
Kitchen and bathrooms: among the items that eat the most budget.
Electrical and lighting: points, units, lighting.
Forgotten items: waste removal, small labor tasks, final touches — these cause the surprises.
The factors that move the finishing cost
Finishing level: economy / mid / super lux — the biggest difference in cost.
Material quality: the difference between one material and another changes the number a lot. (Read: what determines the finishing price per meter)
Apartment area and condition: larger area and more items = higher cost.
Changes during execution: any change after you start adds cost.
How to make a realistic estimate and avoid surprises
Get a detailed take-off for your apartment — a breakdown of each item and quantity, the basis of any accurate estimate. (Read: BOQ guide)
Get an itemized quote, not a lump sum — so you know what you're paying for.
Add a contingency (a small extra percentage) for unexpected items.
Compare more than one quote and understand how the price is calculated. (Read: how finishing is priced)
A tip if you're a finishing company
If you're the one giving the estimate to the client, the accuracy of your estimate = your reputation + your profit. An estimate made "from experience" without a take-off is what leads to a loss or a dispute with the client. A system like Bonyan ERP helps you make an accurate estimate based on real items and track cost during execution.

The cost of finishing an apartment isn't a number you hear from someone — it's the result of planning clear items and a defined finishing level. Account for every item, get an itemized quote, and add a contingency, and your budget will hold steady without surprises.
