Monthly Income From One-time Investment: Everyone wants a comfortable retirement where they don't have to depend on others for their daily expenses. But a comfortable retirement comes with a retirement plan. It's a strategy where you target an amount that can take care of your expenses for your retirement life. Adjusting for inflation, that amount is most likely to be large. So, one needs to plan for years in advance, where they can invest step by step to create a giant retirement corpus.
