The lost Salary and the expenses that I am incurring now along with the interest paid for MBA loan will come to around 92000 GBP. Assuming that I will getting the average salary what an Oxonian got last year I would be able to make around 320000 GBP even if I assume that there are no salary hikes which is very unlikely (In fact I am just assuming the base salary excluding the other benefits). So, still I would be able to make a decent return of around 3% on what I am investing now in 5 years, year on year. Though this is very less, this is a very pessimistic estimate of my ROR after MBA. I am sure that this would cross around 20-50% realistically. The best way to calculate is to ??
