Magento 1.9 Get price from catalog price rule to a SKU programmatically

Question

In Magento, we can use $product->getSpecialPrice() to get the discount price which is set under product view.

Is there a way to get the discount price for a SKU from Catalog Price Rule programmatically?

Answer 1

I found a solution.

Mage::getModel('catalogrule/rule')->calcProductPriceRule($product,$product->getPrice());
