How to save hours per week with our easy differential rent scheme calculator

Differential rent scheme calculator for huge time savings

Labouring with cumbersome spreadsheets and manual processes to calculate rent assessments? Employing a dedicated differential rent scheme calculator can be a huge time-saver. In fact, it can be a complete game-changer.

Approved Housing Bodies (AHBs) across the Irish Republic apply rent to tenants according to local authority rules. Irish county and city councils operate differential rent schemes which calculate rent based on a number of personal and employment criteria. Based on these schemes, each AHB performs complex rent assessment calculations to determine how much rent to charge.

Someone in your housing body has to interpret these rules, and devise the correct formula in a spreadsheet. After that, you must plug in the various employment and household details. However, spreadsheets are notorious for errors when you’re just dealing with cell references. Even if the formula is watertight, the calculation process is manual, long-winded, and prone to error.

What a complete waste of your valuable time!

Complex differential rent scheme calculation

Affinity is a web-based software product created specifically for Approved Housing Bodies in Ireland. One of its key components is a dedicated differential rent scheme calculator, which makes these rent assessment calculations fast, easy and accurate.

One Dublin-based Approved Housing Body told us they used to take a week to process 40 rent assessments. With Affinity’s different rent calculator they can now do 40 per day!

Supports all Irish differential rent scheme policies

As mentioned above, each city and county council across the Republic of Ireland has its own specific rent assessment policy.

They aren’t all easy to read either, often stretching to several pages of long-hand narrative-style text. These policies refer to minimum and maximum rent amounts, fixed rents, and rules for rounding off. You need to obtain household and employment earnings data for the principal or primary earner, as well as any subsidiary or secondary earners. Additionally, factor in dependents and old-age pensioners, and you have so much data to process that even the best-designed spreadsheet can be daunting.

Frankly, the whole rent assessment process can be downright head-wrecking!

Not only are all these various differential rent scheme policies a pain to familiarise with, they often change without warning. Just when you’ve got the hang of a particular policy it is revised.

We have long-standing connections with almost all of the county and city councils across Ireland; the final few are being added in the coming weeks. If and when they revise their rent assessment policies, we update the calculator with the new rules. As a result, you can rest assured your calculations are always correct.

Eliminate human error on differential rent calculations

Many of the differential rent assessment policies are written in longhand, text-heavy narrative. The first task within the housing body is to translate these complex rules into an Excel spreadsheet.

Take the first X of the principal earnings. Disregard A if it exceeds B. Get one sixth of C if it falls between D and E. Round to the nearest Z. And repeat.

Quite apart from the brain-strain, it’s obvious how easily errors can be introduced into these workings.

Make a mistake in the rent assessment, and someone is going to lose out. This may not be simply a monetary loss either. For example, if an error in the differential rent calculation results in an undercharge, you cannot revisit the calculation to fix it. You are stuck with that, and the housing association will lose out on money, potentially a considerable loss.

In contrast, miscalculate a value which results in an overcharge, and the tenant could encounter undue hardship and report your housing body to their local county council or TD. Mess up more than one or two calculations and this could seriously damage your chances of obtaining properties to lease in future. Furthermore, if they raise the overcharge with the Residential Tenancies Board (RTB), the tenant can claim up to €20,000 in compensation.

Hardship from overcharged rent

In short, you simply cannot afford to make mistakes in these rent assessments.

We have turned all of these calculation formula into computer code algorithms behind the scenes. You no longer require an Excel formula guru. With Affinity’s dedicated differential rent scheme calculator you don’t even have to think about them. Plug the values into a straightforward web-based form, and it will give you the rent assessment value along with its workings for reference.

Automatic updates when differential rent policies change

Our Affinity software has been created specifically for the Approved Housing Bodies (AHBs) in the Republic of Ireland. Differential rent scheme calculations are part and parcel of our housing association software. As a result, you can trust our software since these rent assessments are our bread and butter.

Some rent assessment schemes remain static for many years, while others revise their scheme guidelines with little and no warning.

In fact, depending on the closeness of your relationship and communications with your local authority, you could even be using the wrong formula right now. Or the wrong version of the spreadsheet. Spreadsheets are notorious for mutating each time someone downloads or edits them, until eventually nobody is sure which version is the latest and correct one.

Do you even completely 100% trust your existing spreadsheet formulae?

Get the rent assessment calculations wrong and someone with suffer. Most certainly the housing association, but potentially your tenants also.

We have close relationships with the various county and city councils across Ireland. When a local council updates their differential rent scheme calculation guidelines, we introduce a new variation of their scheme in our software. Therefore, when performing your rent assessment, just provide the effective date for the tenancy, and trust that it is using the correct version of the formula.

One less thing for you to worry about. Just perform your rent assessment calculation, file it, trust it, and move on.

Store the differential rent scheme calculation as a PDF

You don’t just have to take our “magic number” and trust it blindly. We provide a printable PDF outlining how the rent assessment value was obtained.

Consider the painful consequences of getting the rent assessment calculation wrong. For example, assess too low, and the housing association loses out. On the other hand, if your assessment is too high, the overcharge could result in hardship, complaints, compensation claims, and damage to reputation.

Printable report

Each rent assessment performed via Affinity’s differential rent scheme calculator comes with a detailed PDF report. This report clearly shows the data you used to arrive at the differential rent calculation, suitable for filing and future reference. This includes all income data you provided for principal and subsidiary earners, along with any other specific employment, household, or personal details required by the particular city or county council.

If you need to perform a new assessment in future, the existing rent assessment printout can serve as a handy reference for the new revised calculation.

Easily update rent assessments if circumstances change

It is quite common for tenants’ personal and employment circumstances to change after you have performed the initial rent assessment. Wheel out the spreadsheet for a new rent assessment calculation? More headaches, and more time lost. On the other hand, it’s very simple and straightforward with Affinity’s differential rent scheme calculator.

New arrival changes household circumstances

Typical reasons why circumstances may change include:

  • Starting a new job
  • Changing employment, or becoming unemployed
  • An increase (or decrease) in employment pay
  • A change in the social welfare entitlement
  • An occupant joins or leaves the household
  • Someone in the household dies, or there is a birth

With the previous assessment readily to hand as an easy-to-read PDF, simply run through the new calculation in a couple of minutes, and get the revised rent value. File this away for future reference. Job done in no time at all.
