I will develop a calculator for information sign and indicator costs

I design and develop online calculators for websites of advertising and production companies that manufacture information signs and indicators. Instead of a manager manually calculating order cost over the phone, website visitors themselves select the needed parameters and immediately see the final price. They specify sign size from a ready grid of standard sizes or enter custom dimensions, select base material — acrylic, PVC, composite aluminum panel, brushed metal or engraved plastic — and mounting method: tape, spacer holders, magnetic mounting or wall brackets.

The calculator recalculates cost in real time with each parameter change, automatically applies discount when increasing the number of signs in the order and shows not just a dry number, but clear breakdown — what makes up the price. This reduces inquiry calls and builds website trust. I move all calculation logic into separate settings: material price, mounting markup and discount thresholds are edited without calling a programmer. I separately consider size validation and adaptive layout for phones.

What's included in the work:
— Customizable price tables by materials and mountings;
— Real-time calculation with cost breakdown;
— Discount thresholds by quantity of signs in order;
— Adaptive widget embeddable in any website;
— Price editing from admin panel without code changes.
