Formula
K0 = R · (1 − q^(−n))/(q − 1)
How the formula works

The present value reverses compound interest: each future pension payment is discounted because a dollar in 20 years is worth less today. The sum of all these discounted payments is the capital that must suffice at the start of retirement. Takeaway: behind a small monthly pension sits a large pool of capital.
