#### Formula:

GDSR = [( p + t + h ) / m ] *100
**Where,**
GDSR = Gross Debt Service Ratio
p = Principal and Interest
t = Property Taxes
h = Heating Costs
m = Gross Monthly Income
Gross debt service ratio is usually expressed in percentage and the value should not exceed 32 %.

#### Example

**Consider the principal and interest as 1000 $, property tax as 300 $, heating cost as 200 $ and GMI as 5000 $**

GDSR = [( 1000+300+200 ) / 5000 ] * 100

= ( 1500 / 5000 ) * 100

= ( 3/10 ) * 100

Therefore, the GDSR Value is 30 %
