Methodology

How finishing cost is calculated: price sources and method

Tashteeby doesn't multiply your area by an "average price per metre". The engine turns your area and room counts into real quantities — square metres of tiles and paint, electrical points, metres of pipe, doors and windows — and prices every line. Here's exactly how.

692,481 EGPExample: 150 m² · 3 bedrooms · 2 bathrooms · standard

Total = the sum of every bill-of-quantities line (quantity × rate) across all trades + the engineering supervision fee. In this example: works EGP 602,157 + 15% supervision EGP 90,324 = EGP 692,481.

1. From area to quantities

The engine splits the area into spaces using fixed assumptions, then derives every line's quantity from them:

SpaceAssumptionIn a 150 m² flat
Each bedroom19 m² of floor57 m²
Kitchen8.25 m² floor, 37.5 m² wall tiles8 + 38 m²
Each bathroom6 m² floor, 33.75 m² walls to the ceiling12 + 68 m²
Reception, corridors, balconiesThe remaining area (at least 20%)73 m²
Painted walls2.5 m² of wall per m² of floor375 m²
Electrics and plumbingPoints, cable and pipe that scale with area and the number of wet roomsline by line
If your flat differs from the assumptions (a large master bathroom, a smaller reception), Premium lets you edit the quantity on any line — and Plan Studio reads the room sizes from your own floor plan.

2. Material and labour rates

Every line has a unit rate covering material, labour and any consumables (cement and sand for tiling, for example). 19 core rates are refreshed from Tashteeby's Cairo price database; the rest (sanitary ware, electrical fittings, fit-out) are reference prices built into the engine.

Examples of live ratesPrice
Porcelain (m²)330
Ceramic 60×60 (m²)185
Tiling labour (m²)95
Paint material (m²)85
Painting labour (m²)53
Aluminium, small profile (m²)2,900
Turkish front door11,800

3. Finish level and supervision

  • Finish level changes the material on lines with alternatives (ceramic or porcelain, aluminium profile, wood type, front door) and the brand tier for fixtures and electrics — quantities stay the same. See the levels compared.
  • Engineering supervision is a percentage of the works (15% by default; you can pick 10% or none). It applies to finishing, kitchen and A/C — not to furniture and appliances, which are bought ready-made.
  • Unit condition adds or removes stages: plaster for red brick, demolition and debris removal for old finishes, while semi-finished removes the rough-in.
  • Duration is derived from each trade's quantities and one crew's output, with the natural overlap between stages — see the finishing stages in order.

4. How prices are updated

1Collecting pricesThe Tashteeby team collects average Cairo market prices for materials and labour and reviews them regularly.
2Publishing the price databaseNew prices are published with a clear update date and appear on the prices page.
3Every figure updates itselfThe calculator, the apps and every number in these guides are computed from the same prices when the page loads, so no figure is left behind.

5. What the estimate doesn't cover

The estimate is a budget guide and a benchmark for comparing contractor quotes — not a quotation. These can move the real number:

Brands and formatsThe same material varies by brand, format and quantity.
Site conditionsA high floor without a lift, hard access, or walls needing repair.
Area and contractorLabour rates and contractor margins vary by area and firm.
Works not includedStructural works, permits, exterior façades and bespoke interior design.
Our advice: take the line-by-line bill of quantities and compare it with your contractor's quote line by line — any big gap on a line is the question to ask.

Frequently asked questions

How accurate is the calculator?
It works from real quantities and current market prices, so it's a solid benchmark for budgeting and comparing quotes. The final figure depends on brands, site conditions and the contractor — always confirm with a written quote.
How often are prices updated?
Regularly — the last update date is always shown next to the prices (last update: ).
Why does my quote differ from the estimate?
Usually different quantities, brands, supervision or contractor margin. Compare the bill of quantities line by line to see where the gap comes from.
How is supervision calculated?
A percentage of the works (15% by default) on finishing, kitchen and A/C, excluding furniture and appliances.
Can I edit quantities and prices?
Yes, with Premium: edit any quantity or rate in the bill of quantities, or remove lines, and the total and duration update instantly.
