What is MegaCalculator

MegaCalculator integrates seamlessly with OpenCart, extending its capabilities far beyond standard price settings.
You can design your own formulas to calculate the total cost of any product or service — from simple square meter prices to complex multi-step configurations.

The module supports:

• Unlimited parameters and options

• Conditional logic and mathematical operations in formulas

• Working with both attributes and options

• Real-time price updates without page reload

• Mega-related products (linked items calculated and added to the cart automatically)

The module can handle almost any type of calculation or configuration.

Popular real-world examples include:

• Printing and signage: banners, business cards, posters, boxes, and packaging

• Interior printing: canvas art, photo frames, and posters

• Flooring: laminate, parquet, linoleum, carpet — calculated by area and packaging

• Wallpapers and photo wallpapers: with automatic glue calculation

• Mirrors and glass: by size and frame type
