About

A 30% deduction is a powerful psychological trigger in retail. It often marks the transition from a "standard sale" to a "clearance event." For consumers, understanding the true impact of this discount allows for better budgeting during major shopping holidays like Black Friday. For retailers, accurate labeling of 30% off prices is a legal requirement in many regions.

This calculator is built with value reinforcement in mind. Beyond simply displaying the final price, it generates a visual Savings Badge. This element emphasizes the amount saved, helping users visualize the tangible benefit of the deduction rather than just the expenditure.

Formulas

To calculate the New Price P_new and the Savings S:

S = P_orig × 0.30

P_new = P_orig − S

Frequently Asked Questions

First, find 10% by moving the decimal point one spot to the left (e.g., 10% of $50 is $5). Then multiply that number by 3 ($5 × 3 = $15). Subtract that from the original ($50 - $15 = $35).

Buy 2 Get 1 Free is effectively 33% off, but only if you buy exactly 3 items of equal value. A flat 30% off is often better because it requires no minimum purchase quantity and applies to single items.
