Degree day table

In DIN 4713-5, the so-called degree day table defines how the heating costs are distributed over the individual months or days with annual readings.

month	Percentage ownership ‰	Share per day in ‰
January	170	170/31 = 5.48
February	150	150/28 = 5.35 150/29 = 5.17
March	130	130/31 = 4.19
April	80	80/30 = 2.66
May	40	40/31 = 1.29
June to August together	40	40/92 = 0.43
September	30th	30/30 = 1.00
October	80	80/31 = 2.58
November	120	120/30 = 4.00
December	160	160/31 = 5.16

Calculation example

There were 1000 euros heating costs for the apartment over a year. The apartment was rented for 15 days in November. The distribution of heating costs for these 15 days results from the following calculation according to the table:

1000 euros × (120 ‰ / 30 days) × 15 days = 60 euros.

According to the degree day table, 120 ‰ of the annual costs are divided for November. November has 30 days and the apartment was rented for 15 days. This results in heating costs of 60 euros.
