| Item | Formula / Rule | Source / Standard |
|---|---|---|
| Net single premium | NSP = Σ vk+1 ×k|qx × b with v = 1/(1+i) the discount factor | Bowers et al. 1997, Actuarial Mathematics, Ch. 4 |
| Interest sensitivity | A higher assumed interest rate lowers the discount factor and therefore the net single premium | Bowers et al. 1997, Actuarial Mathematics, Ch. 4 |
| Equivalence principle | The net single premium covers benefit present value only, excluding loadings, so it is below the gross premium | Bowers et al. 1997, Actuarial Mathematics, Ch. 6 |
