Sometimes when sending dash you want to figure out the fees that get added.
On the main dash.org page a calculator that actually tells you the fees.
You can enter 5 dash then select your options, including instant and darksend.
Just use Coin-Control in the wallet
It'll tell you the fee(s)
edit: besides, a calculator will not know the difference between 5DASH from (1) transaction and (100) transactions of 0.05DASH - the latter costs more due to the SIZE of the transaction
A 5 dash transaction fee
is not the same as a transaction fee for (100) x 0.05 DASH
