What this calculator compares
Define the same repair unit with both providers: for example one door with its agreed hinges, or one drawer with a pair of runners. Do not compare a price per hinge with a price per door. Use whole-job totals for mixed work.
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, not a market price: four agreed repair units at AED 80 labour each plus AED 120 hardware and AED 60 finish work total AED 500 before VAT, or AED 525 if those provider amounts exclude 5% VAT. A pair of runners is not automatically two repair units.
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 calculator cannot establish the strength of a fixing or cabinet. Keep a loose or unstable door/cabinet out of use and ask a competent provider to assess it; do not infer suitability from the lower price.
