What is this tool for?

Increased Last Price Formula

The specified raise rate of that price is added to the original price you have: Base Price + (Base Price × Rate / 100).

Finding the Hidden Raise Rate

If you know the old and new form of a product, our tool performs the ((New Price - Old Price) / Old Price) × 100 calculation and shows you the raise as a percentage.

Retrospective (Without Raise) Price

When you enter the current shelf price and the percentage of the raise, we look for the naked price with the Raise Price / (1 + Rate/100) formula mathematically.

Negative Values (Discount)

The raise process indicates a mathematical direction. When you put a "minus" (-) in front of the raise rate you enter into the system, it becomes a perfect discount calculator.

When should you use this?

Calculating price increases or personal income raise processes in market conditions can lead to mathematical errors and wrong budget constructions when done manually. Our 100% free and online Raise Calculation tool, developed for you, algorithmically calculates any kind of percentage increase and decrease instantly, from salary increases to changes in rent and product prices.

What Does This Tool Do?

Most people fall into a serious error by doing percentage subtraction when they want to return from the raised price to the old price. Our raise calculator provides you with 3 basic operations in seconds by hiding these complex financial formulas in the background:

Applying Raise:

Determines the new price tag by adding the desired percentage increase to the base price.

Detecting Price Raise (Finding the Rate):

When you see that a product on the market shelf was 100 TL yesterday and 135 TL today; it reveals exactly "what percentage raise" this product has received.

Finding the Principal Without Raise:

When you know the already raised product and the percentage of the applied raise, it allows you to descend to its naked price before the raise wave (reverse engineering).

In Which Cases Is It Used?

This tool is indispensable for both corporate firms and individuals for a correct financial awareness:

Salary and Wage Increases:

While calculating how many liras the information of "A salary increase of 35% has been made to you" coming from Human Resources will reflect on your bank account (gross/net).

Official Rent Increase Rate Detection:

In determining your new house rent over the TEFE-TUFE inflation rates on the agenda or based on agreements like "%25 legal limit" made with the landlord.

Retail and Inflation Analysis:

When you want to learn what percentage raise milk or cheese has received compared to a month ago in your daily market shopping.

Commercial Cost Determination:

At the stage where business owners add this cost to the sales price by protecting their own profit margin after the raise made to the product by suppliers.

How Does the Raise Calculation Algorithm Work?

The biggest construction done wrong while using a calculator is "reverse operation". For example, when a 20% raise is applied to a 100 TL sweater, the price becomes 120 TL. However, if you apply a 20% discount to a 120 TL sweater to "return to its old state", the price drops to 96 TL and you cannot reach the original price! The reason for this is the mathematical division obligation. Our tool brings you to the correct result by processing the formula Raised Price / (1 + Raise Rate) with a single click without the need for you to know these formulas.

Frequently Asked Questions

It is found by adding a certain percentage over an amount. For instance; if a 25% raise is made to a rental fee of 5,000 TL, the new fee becomes 5,000 x 1.25 = 6,250 TL. Our tool performs this multiplication flawlessly.
Absolutely! When you select the "Raise Rate Calculation" tab, our tool analyzes the mathematical difference between the first price and the last price of the product or salary and extracts the percentage change (raise rate on % basis) for you.
In the scenario of "The 130 TL version of the product with a 30% raise", finding the old price is NOT subtracting 30% from 130. Our tool provides the correctness of this common mistake in math at the equivalent of (130 / 1.30), i.e., as 100 TL.
Yes, discount is actually a negative-directional raise. You can quickly detect the final price of a product in the discounted basket by entering values like -15, -20 into the raise rate section.
Since it works with a numerical algorithm, you can use this tool for percentage changes and raises in any unit such as Dollar, Euro, Gold gram price, or crypto money values, not just TL.
