Difference between Fixed method Depreciation and Written Down Value Method?

Fixed method of depreciation is based on Fix rate on Asset amount. say if asset value is $100,000 and depreciation is @ 10% then this depreciation expenses is $10000

with fixed method Depreciation value (10,000)  will not change.same depreciation is charge for coming years

Reducing Balance Method/Written Down Value Method is calculated on asset balance each year. say if asset value is $100,000 and depreciation is @ 10% then  depreciation expenses is $10000 for 1st year but in 2nd year depreciation is based on Asset value $100,000-10,000=90,000*10%=9,000

with written down value method  depreciation is calculated on asset balance every year

in case of fixed method the rate of depreciation is fixed in the value of assets.but in case of written down  method  the value of depreciation  rate has been decided on the reducing value .

In Fixed Method Depreciation assets value become NIL and in Written down Value Method Assets Value never becom Zero.
