What this calculator compares
One leaf is one moving door panel, not one opening or one face. Specify one/both faces, edges and the frame/architrave coverage. For per-face rates, ask the painter to extend the price to the agreed faces per leaf before entry; never multiply a both-sides rate twice. Use whole-job labour and materials totals for different sizes, substrates, preparation or finishes. Do not add mutually alternative packages. Enter all provider amounts on the same confirmed VAT basis. Customer purchases use the final whole-job receipt total including retail VAT, never a per-item amount. If you buy the main product, put separately billed provider components in the relevant extra, without duplicating them. Required unpriced costs stay unknown, not free. Enter full project costs, not a balance after a deposit; booking payments and refundable security deposits are recorded separately, not added as extras or deducted as visit credits.
This tool calculates from your entered quotations; it does not estimate a market tariff or verify a provider. Blank prices, unknown tax terms and unresolved extras keep the result incomplete. You must confirm the topic-specific scope checks before a cost difference appears.
How the arithmetic works
Labour is either the entered whole-job total or a per-item amount multiplied by the shared item quantity. Separate provider parts use the same unit choice. Each visit and extra charge is a whole-job amount added once. Use agreed whole-job totals for mixed models, repair units or prices.
Provider amount = labour/package + separately charged provider parts + visit + extras − eligible visit credit. A credit cannot exceed either the charged visit fee or the entered provider work excluding that visit. It cannot offset customer-bought parts. An included or no-charge visit is not deducted again. This model does not handle a separate cash refund arrangement.
The standard UAE VAT rate is 5%. VAT is added once to VAT-exclusive provider amounts, and not added to amounts already including VAT or confirmed not charged. Enter all of one provider’s amounts on the same VAT basis.
Project cost = provider total after its VAT treatment + your separately purchased parts at their final retail total, including any retail VAT and delivery. This keeps customer-supplied parts visible without taxing them twice. Already-owned parts count at the value you explicitly enter; entering zero deliberately excludes their historic purchase cost. No deposit or prior payment is deducted, so the result is not a remaining balance.
A worked example
Illustrative arithmetic only, not a market rate: three matching leaves at AED 100 labour each, AED 60 separate provider coatings and AED 90 agreed trim work total AED 450 before VAT, or AED 472.50 if all provider amounts exclude 5% VAT. Both faces are already in each leaf rate. The visit and every other required line are confirmed included or not needed.
Assumptions and limits
Money is entered in AED with up to two decimal places. Each monetary field is limited to AED 1,000,000; item counts to 100; handyman lists to 12 rows; hours to 100; and technicians to 20. These are input-error safeguards, not market, capacity or safety limits. Invalid values are not silently rounded into valid inputs. Calculated monetary lines, VAT and totals are rounded to two decimal places.
Unentered damage, scope changes and future work are excluded. The known-provider subtotal uses the amounts as entered, without adding unconfirmed VAT or customer purchases; it is not an all-in quote. Even a complete cost comparison does not certify suitability, workmanship, insurance or approval.
The tool cannot assess coating compatibility or repair damp, swelling or loose veneer. Do not strip unknown finishes or alter fire-door labels, seals or hardware as a cosmetic task; ask management and a suitable specialist about rated doors. Dry-looking paint is not proof of full cure.
