How to Use BidCalc
1
Choose your situation I Have a Budget — you know your total spend limit. BidCalc tells you the highest bid you can call without going over.

I Have a Bid Price — you've decided what to bid. BidCalc shows the exact total you'll pay once all fees and VAT are added.
2
Load a preset Tap a chip (e.g. "Bid Or Buy") to load typical fees for that auction house. You can still adjust any value after loading.
3
How VAT works VAT (15%) is added to the full subtotal — bid price + commission + all flat fees — then added on top. Same as how a retail price tag works.
4
Save & share Tap "Save to History" after calculating. Tap the share icon in the top right to copy a summary for WhatsApp or email.
5
Install offline In Chrome: tap the menu → "Add to Home Screen". Works without internet — perfect for auction day.
