Methods for calculating harmonised Social Benefits in different life situations

This page explains how income levels and compensation rates are calculated for different life situations in the Nordic countries. The aim is to provide a consistent and comparable framework for analysing how welfare systems support individuals during events such as unemployment, sickness, or retirement.

The purpose of the calculations is to examine the dissimilarities among all the similarities, as the Nordic countries are defined by an elaborate social safety net and a universalistic welfare state.

The Nordic social protection systems can as such be seen as variations of the same model, and therefore there is much to be learned from comparing the countries.

Calculations are country specific and comparable

The calculations used for the life situations are designed to make country specific data as comparable as possible across the Nordic countries. 

The calculations reflect the income levels for households receiving benefits in case of a social event, compared with the level of regular labour market income in the Nordic countries. Compensation is expressed as a percentage of income prior to the social event. 

For example, if the social event is job loss, income after becoming unemployed is compared with previous earnings while in employment. Based on this comparison, compensation rates are calculated for different life situations and across a range of pre-event income levels.

Harmonized calculations

To make sure that the calculations are comparable across countries, the calculations are harmonized. This is important to make meaningful comparisons possible, but also for understanding the results.

In general, all calculations are made according to the most recent rules and regulations. For the same reason calculations are always expressed for a specific year. The rule of thumb is that rules and regulations used are those in force by 1st of January of the year in question.

When calculating disposable income, housing benefits and payments for day-care are included. Both expenditures are dependent on household size and income, which therefore plays a substantial role when calculating the compensation rate following a change in life situation.

In the case of social assistance benefits, the disposable income is calculated following the subtraction of rental costs.

Tax payment

The calculation uses average national rates of taxation i.e., average local authority rates of taxation, as well as the state tax. Tax deductions (for example basic deduction and earned income tax credit) are included. The public service broadcast charge is also included in the tax.

In Denmark the church tax is voluntary. However, it is paid by more than half of the population. In the calculations for couples in Denmark, it is assumed that only one person pays church tax. In all Danish calculations for couples, it is the person with the highest earning, who is estimated to pay church tax.

In Finland the church tax is voluntary, a person may opt out of it by resigning from the church. Because of this opt-out possibility the church tax is classified as a voluntary membership fee and thus not considered in Finnish life situation calculations.

In Norway there is no church tax, and it is therefore not included in calculations.

For Sweden, the church tax (which is voluntary) is not included from year 2016 onwards, the funeral fee (not voluntary) is included for all years. 

In the Faroe Islands, the church tax is voluntary and is included in the data. 

Gross income

Gross income consists of income from work, and excludes e.g., child allowance and housing benefit.

Disposable income

Disposable income is calculated as:

Disposable income = gross income + child allowance + housing benefit, - income tax, - social security contributions payable by employees - charges payable for day care institutions. 

For relevant cases, unemployment fund contributions are included in the calculation of disposable income.

For Denmark, Finland and Sweden, the social security contributions payable by employees include contributions to the voluntary unemployment insurance scheme, in the form of membership fees paid to unemployment funds. The Danish calculations also include union contributions. Norway, Iceland and the Faroe Islands have mandatory unemployment insurance fees.

Disposable incomes are calculated on a yearly basis, both for the employed and for those receiving various social benefits. The calculations assume that those concerned receive social benefits throughout the year, even where this is not the case (e.g., parental benefit). The listed incomes per month are the annual amounts divided by 12.

Equivalent disposable income

To enable comparisons between households of different sizes, a household’s disposable income is usually divided by an equivalent weight. On this website, the modified OECD scale (also used in EU-SILC) is applied. 

On the OECD scale, the first adult in the household is assigned a weight of 1. Any other adults are assigned a weight of 0.5. Children between 0–13 years are weighted at 0.3, whereas older children are weighted at 0.5. 

Therefore, for a couple with two young children, the equivalent weight is:

1+0.5+0.3+0.3 = 2.1. 

If the annual disposable income of a household is DKK 500 000, the equivalent disposable will be: 500 000/2.1 ≈ DKK 238 000.

Compensation rate

The compensation rate is calculated by comparing income following a change in life situation (e.g., in the event of unemployment, income in the form of unemployment benefits), with the income one would have earned from work had the change not occurred. The calculation uses equivalent disposable incomes, with the resulting compensation rate given as a percentage:

Compensation rate = eqv. disp. income after / eqv. disp. income before.

Children’s age and use of day care

Child allowances and charges payable for day care is calculated based on the following households: 

  • A single parent with an infant of 0 years i.e., childbirth as a life event 
  • A single parent with a child aged five attending day care. 
  • A couple with two children aged five and eight i.e., one child attending day care and one child attending school but in need of after-school care.

For Denmark charges payable for day care are calculated based on average charges and the national rules governing payments. 

For the Faroe Islands, calculations are based on the rates that apply in Torshavn. 

In Finland, it is assumed that other children of preschool age also make use of day care facilities, albeit on a part time basis only. The rates used are the ones applied in Helsinki.

For Iceland, calculations are based on the rates that apply in Reykjavík.

In Norway, it is the rates that apply in Oslo.

For Sweden, calculations are based on rates that apply in Örebro, as an approximation of an average municipality.

Except for the new-born child, it is assumed that the children are attending day care. In Sweden, the children are not allowed fulltime day-care if you are unemployed, therefor the charge is not calculated for unemployment.

For child allowances, the calculation includes child maintenance payments for single parents (corresponding to the amount of the contributions payable in advance by the public authorities), in addition to the actual child allowance to single parents and couples with children.

Housing costs and housing benefits

In all calculations, it is assumed that the families live in rented accommodation. 

The amount of the housing costs/rent depends solely on the household and is independent of income level. Housing costs include rent payments. For the life situation involving social assistance, heating costs are also included. 

It has not been possible to determine the amount of rent for the individual households in a manner that is consistent across all the countries. 

In some countries, the rent is based on an estimate of the amount spent on rented accommodation per household, as well as the national average rent per square metre. In others, it is based on survey data of rents for various households in certain local authorities. 

Except for the life situation involving social assistance, the rent for the individual households are merely used to calculate the amount of any housing benefit – the rent itself is not included in the calculation of the disposable income.

For the Danish calculations, the rents are based on the national average rent per square metre. It is assumed that a single person without a child, or with a newborn, lives in a 70 sqm space, and that single parents with one child live in 85 sqm. Couples with no children or with a newborn are estimated to live in 85 sqm, whereas couples with two children are estimated to live in 100 sqm. These housing sizes are also applied when calculating housing benefits.

In the Faroe Islands the rent is based on a typical home with the Faroese housing association in Torshavn.

The rents in Iceland are based on data that applies only to Reykjavik. 

For Norway, the rents are based on the data for Oslo in the first quarter of the relevant year. In this case, the assumption is that the rent depends on the size of the household. Furthermore, housing benefits are estimated by means of Husbanken’s housing benefit calculator. It also uses the Oslo rates.

The rents in Finland are national averages for the recipients of housing aid within the specific household composition in question.

For Sweden, data from the microsimulation FASIT is used. The rent is based on data for people applying for housing benefits and then imputed for similar apartments. The median for each household type is used. The rents are adjusted to current year’s rent level with statistics from a survey.

Note: Year of data: Finland=2021, Denmark, Faroe Islands, Sweden=2020, Norway=2017, Iceland=2016

Comparing different income levels

To measure different levels of income across countries, the standard OECD concept of Average Worker (AW) is used. Definition of AW is the average income for a full-time waged worker in the private sector. Four different percentages of AW are the basis for the calculation of compensation rates: 50, 75, 100, and 125 per cent of AW. 

The income of 75 per cent of AW that is considered to represent the most frequent income level and is used in the presentation of graphs, but other percentages of the AW are available in the database.
