Barack Obama's net worth is currently estimated to be $40 million.

Aside from the six-figure pension he receives as former president, Obama has made millions from speaking engagements and his bestselling books.

While Obama spends his money in various ways, he loves to donate to charity and take vacations with Michelle.

Former President Barack Obama is a busy guy.

From speaking at events around the world to writing a memoir, and, most recently, signing a massive production deal with Netflix, Obama's life after the White House has been full and very lucrative.

These endeavours — along with the six-figure pension all former presidents receive — have significantly contributed to Obama's current estimated net worth of $40 million.

From the time he joined the US Senate in 2005 to the end of his presidency, Obama made $20 million alone from his presidential salary, book royalties, and investments, reports Forbes. And based on all the projects he's taking on in just his first year post-presidency, we can only expect him to make many millions more.

From philanthropic efforts to vacationing where the sun shines to making long-term investments his daughters' education, see how Obama spends his fortune.
