This calculator is the free tier. The Site Office is the upgrade.
A free account saves projects to the cloud. Dedicated Site Office workspaces take the same BOQ into execution: Gantt schedules with physical & financial progress, RA bills that snapshot rates at finalisation, variations, vendor bills, and muster-roll cost ledgers — with a tracking link your client can open like a courier parcel.
BOQ calculator — frequently asked questions
Is this BOQ calculator really free?
Yes. The calculator, rate analysis, and Excel export are free with no sign-up. Your BOQ is saved in your own browser, on your own device. A free Calenote account adds cloud-saved projects, and Site Office workspaces add Gantt schedules, RA bills, variations and cost ledgers on top of the same BOQ.
How does the rate analysis work?
Each BOQ item can carry a recipe — the material, labour and equipment quantities needed per one unit of the item, DUDBC-norms style. The item's rate is then computed from your resources table, so when a market rate changes (say cement), you edit it once and every recipe item, subtotal and the grand total re-price instantly.
Does it handle VAT and overhead & profit for Nepal?
Yes. Overheads & profit is applied as a percentage (15% by default, editable) on the direct cost, and Nepal's 13% VAT can be toggled on the subtotal — the standard build-up used in quotations and government estimates.
Can I export the BOQ to Excel?
One click exports an .xlsx with the full quotation — sections, items, rates, subtotals, O&P, VAT and grand total — plus a second sheet showing the rate build-up of every analysed item, ready to attach to a tender or send to a client.
How do you calculate VAT on a BOQ in Nepal?
VAT of 13% is applied to the subtotal after overheads and profit, not to the direct cost alone. The order is: sum the item amounts to get the direct cost, add the overhead and profit percentage, add contingency if the job carries one, and charge 13% VAT on that subtotal. Showing VAT as its own labelled line rather than folding it into rates is what clients and auditors expect.
What is the standard overhead and profit percentage in Nepal?
15% on direct cost is the figure most commonly used in Nepali practice, and it is the default in this calculator. Public tenders sometimes prescribe or cap the percentage in their conditions of contract, so check the tender documents before submitting. The field is editable for exactly that reason.
How do I convert a rate from cubic metre to cubic foot?
One cubic metre is 35.3147 cubic feet, so a rate per cubic metre divides by that figure to give the rate per cubic foot: Rs 13,234 per m³ becomes about Rs 374.75 per cu.ft. The calculator does this automatically when you change an item’s unit, because getting it wrong overstates the work by more than thirty times.
Is my data uploaded anywhere?
No. Without an account, everything stays in your browser's local storage — nothing is sent to any server. Clearing your browser data clears the BOQ, so export to Excel for anything you need to keep.
