The former. The main factor is don't want to wait the whole 20 years so wondering what is a good lumpsum replacement.

Whats your age, sex and what interest do you want?

I need these to calculate the present value of it. Since mortality is affected by sex and age.

I need the mortality because if you die, the payments of 50 000 stops. Unless they are guaranteed for the 20 years then mortality doesnt play a factor.

Mortality is not a factor, let's assume it is transferrable to any beneficiary. Don't understand the interest question. TX.

Sorry, I'm obviously bad at this lol. I dunno, we could try the avg bank savings rate?

Also besides the strict AS answer, wonder what ppl (most RFDers are somewhat financially-astute) feel is an acceptable lumpsum in lieu of waiting 20 years.

50000$/ year, paid at end of each year, for 20 years has a present value of about 623000$ assuming 5% interest. The interest can be seen as inflation (AKA) things are more expensive and thus your 50 000$ will buy you less thing in year 10 than it did in year 2-3.

The website has a formula which you can use. For your case PMT = 50000, n = 20 and r=interest rate. You can then plug the formula and number into a calculator and run the scenarios youself.

This question isnt actuarial science but more financial/annuities.

If you were to include mortality then actuaries would be involved in it.

Did you win a $1,000,000 lottery that will pay out over 20 years?

Anyways, you still need the annuity investment rate for that $50,000 payment. Assuming it is 4%, it would be worth $679,516 if it starts paying out a year from now or $706,696 if it starts paying out immediately.

You can use an online TVM calculator to play around with other values.
