What this calculator compares
Count complete blind units, not windows, individual slats, cords or chains. One window may have several blinds. Use per-item rates only for the same diagnosed repair on matching units; ask providers to extend other units or use whole-job totals for mixed mechanisms. Motorised repair does not imply a complete replacement motor. A replacement quote may be recorded separately, but do not confirm matching scope between repair and replacement. 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: AED 200 whole-job labour, AED 120 provider parts, AED 30 access and an AED 80 assessment less an agreed AED 50 eligible visit credit total AED 380 before VAT, or AED 399 if all provider amounts exclude 5%. Every other required line is confirmed included or not needed. The credit is not assumed from the assessment alone.
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.
Keep children away from accessible cords and loops. Do not knot cords, bypass safety devices, dismantle springs or open mains-powered mechanisms. Stop use for unstable mounting, damaged wiring or overheating; the lower price is not proof of child safety or electrical suitability.
