The rate or percentage factor determines how the baseline value expands, discounts, or incurs expense over the modeled period.
Discount rate / expected investment return (%)
The timeframe or secondary parameter provides essential context, defining the duration or conditions under which the math operates.

Frequently Asked Questions
Should I take the pension annuity or the lump sum? ▼
Take the annuity if you prefer guaranteed, risk-free lifetime income and have no desire to manage investments. Take the lump sum if the offer exceeds the actuarial present value, you desire investment flexibility, or you wish to leave an inheritance.
How does the discount rate affect pension present value? ▼
A higher discount rate lowers the calculated present value, while a lower discount rate increases it. The discount rate represents your opportunity cost of investing the lump sum.
