Calculate Take Home Pay

Because of my extensive background in payroll I am often asked by people to check their pay slips for accuracy. They are happy when I can verify independently that everything is in order. The other question I get asked is “if I was earning €200 a week more how much would it be worth to me in my hand”.

Interactive Gross Pay to Net Pay App.

In 2019 I checked the internet for an interactive converter that would calculate net pay for a person in a given pay period for a given taxable pay. There was nothing on the Web that does this properly so Boyle Practical Project Management developed an interactive gross pay to net  application and tested it against hundreds of scenarios for different pay cycles. This gross to net pay calculator calculates tax (PAYE), pay related social insurance (PRSI), and universal social charge (USC) for any given period.

How Much is it Worth Into My Hand?

The target audience for the Calculator is employees on the front line, at the cold face interacting with customers, in offices, on shop and factory floors. For a multitude of reasons but mainly because of scale many businesses simply do not possess the resources to assist employees with either normal or hypotheical wage queries. For example:

If I took the supervisor job, how much would it be worth to me into my hand?

If I was to work 20 hours overtime how much tax would I pay on it?

How do I know if my pay is calculated correctly?  

Difference Between Gross Pay and Taxable Pay

When using the application or making queries relating to wages it is important to distinguish between gross pay and taxable pay. Gross pay is the employee’s pay of any kind, including:

Basic pay
Notional pay
Pay before any pension contributions deductions are made

Chapter 3 of the Employers Guide to PAYE details the different types of pay that would be included as Gross Pay. Taxable pay is your gross pay less any contributions you make to a:

Revenue approved pension scheme
Revenue approved Permanent Health Benefit (Income Continuance) scheme
Personal Retirement Savings Account (PRSA)
Retirement Annuity Contract (RAC)

These amounts are deducted from your gross pay before your employer calculates your tax. On the Gross to Net Pay Calculator these are referred to as Non-Taxable Deductions.
