Personally, my experience with Amazon thus far has been good - a few of my short eBooks generate steady passive income on weekly basis with zero additional effort from my side. One thing to note though - Amazon pays 70% royalty on each eBook sold only if your eBook is priced between $2.99 to $9.99. Less than or higher than that pricing structure, the royalty decreases to 35%.of your book’s listed price.
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.
