Percentage Calculator - percent, discount, tip

By Omni Calculator Sp. z o.o.

This app is only available on the App Store for iOS devices.


Percentage Calculator is simply the best and easiest to use app which calculates:

*** Everyday calculations
* simple percentage calculator (5 percent of 40 is 2)
* percentage increase/decrease (5 percent decrease from 40 is 38)
* tip calculator
* discount calculator
* convert fractions to percentages (5 / 20 is the same as 25 percent)

*** Business calculators
* markup
* profit margin
* Sales tax
* a powertul trader's calculator (VAT or sales tax, net cost, gross cost, markup/profit margin, my net price, my gross price and profit all in one calculator)
* compound interest
* loan payment
* cumulative growth
* Compound Annual Growth Rate (CAGR)
* inflation
* doubling time (rule of 72)

Percentage Calculator's strongest feature is that any value can either be a source or result of a calculation - just enter the values you know and it will tell you the remaining ones!
Percentage calculator is useful in many real-life situations:
* school (mathematics, statistics, algebra)
* business and finance (markup, profit margin, profit, loan payments, cumulative growth, inflation, doubling time, investment return rate, loan interest rate, markup, profit margin, company profits changes)
* shopping (discounts, comparison of two products that differ in quantity)
* tipping
* cooking (ingredients are often shown in percentages)
* health (body mass index, fat percentage in food)

Percentage calculator is an app for people who don’t like math :-)

Updated review

I have to update my review. Just realized they have since lowered the price of the ad removal to $2.99 and I have concluded this is a decent price for an app that I use quite often (also got tired of hitting the ad by accident instead of hitting the keys). Hopefully the devs keep it up because this one is still the best around.

I do have one request: shortcut keys to move up and down between rows (boxes). Maybe even a left and right to correct mistakes rather than tapping and dragging. Seems like it would make multiple calculations faster. Thanks!

I went ahead and updated thinking, this is a decent app, I'll pay to have ads removed. Then upon launching the app I realized it was 5 bucks to remove them. 5 bucks!! You've got to be kidding me. Time to delete and find another....sorry but that is absurd imo.

Shady, real shady guys

Had this app so long and used (until today!) it so much I used to recommend it. Now there's forced ads. Pretty sure this was an app I paid for, sorry I'm not sure - so forced to doge around ads to use it, or pay the now 5 bucks hostage fee to use an app I've been using more then a year is just aggravating and why support a business that aggravates you ?

Time to look for a different app.

Looks like the best

After downloading as many percentage calculators as I could for review, this one came on Top. It's the best for my needs.
