How Big Of A Goal Is This?
5 Million. 10 Years. A naive way to calculate this would be to divide 5 million with 10 years–so per year I’ve gotta earn around 500 thousand dollars. Which is a joke really, considering my current income level
But it’s actually a bit more complicated than that, just like we can see from Paul Lutus‘s excellent financial calculator here. There are 5 factors that we can play with:
- Present Value (PV). This is the money that you have, now. Obviously the greater this number is, the better! If I already have $5 million NOW, then I won’t need to have this 10-year project in the first place.
- Future Value (FV). This is the money that you want to have in the future.
- Number of Payments (NP). This is the number of payments. Let’s say in 10 years, I manage to put 100k every year. That means I make 10 payments. On the other hand, if I put, say, 10k every month, then I make 120 payments.
- Payment Amount (PMT). This is in negative because the money is taken away from us (by the bank, for investment, etc.)
- Interest Rate per period, in % (IR). This is the interest rate during that period. Meaning, let’s say I make 12 payments in a year. Then I should put the monthly interest and not the annual interest.
Now the interesting thing is that, with these 5 parameters, if you set 4 of them, you can always calculate the remaining one. So for the purpose of this blog, we know that:
PV = 0. I don’t start with any money.
FV = 5,000,000. The end goal.
NP = 10 years, so assuming months, there are 120 payments, and 120′s what we’re gonna enter.
Interest rate = Since we’re using monthly payment period, we have to use monthly interest as well. Let’s be convervative and put this at 0.5%.
The calculator tells us the Payment amount: I have to put in more than thirty thousand dollars per month to reach this target.
No matter how you look at it, 5 million is a HUGE target for me! To be honest, I’m not sure yet how I can get there. But I’m sure it can be done though!
