How to form it

Examples
どんなに勉強しても、テストで100点を取れない。

いくら説明しても、父は分かってくれません。

When to use it
どんなに〜ても and いくら〜ても mean "no matter how (much)": the result stays the same however far the action or quality goes. いくら食べても太らない means "No matter how much I eat, I don't gain weight." The result is often negative or disappointing, but it can be positive too.
Nuance
Both are common in speech and writing. いくら focuses on amount or repetition (いくら呼んでも); どんなに focuses on degree or effort (どんなに大変でも). In casual speech, いくら〜たって is also common.
Compare
たとえ〜ても imagines one extreme case: たとえ失敗しても. どんなに and いくら talk about degree. ても alone has no "how much" sense. Do not confuse this いくら with いくら meaning "how much does it cost."
Tip: どんなに pairs well with adjectives (どんなに忙しくても); いくら pairs well with repeated actions (いくら言っても). Both need ても or でも later in the sentence.
