Describe one benefit stream on a consistent timeline
Enter the first annual benefit, number of payments, years until retirement, benefit-growth rate and discount rate. Salary is used only to express the annual contribution equivalent as a share.
The timing matters: retirement value prices the stream at retirement, while present value discounts that retirement amount back across the entered years until retirement.
- Confirm whether the first payment belongs at the start or end convention used by the calculator.
- Use a benefit-growth assumption that matches the scenario being compared.
- Use the same entered rate for discounting and contribution accumulation when interpreting the equivalent.
- Do not substitute the result for a plan statement or transfer quote.
Value the benefit stream before solving for contributions
The calculator discounts the entered sequence of retirement payments to a retirement-date value, then discounts that amount over the ten-year wait to obtain today’s value.
It next solves for a level annual contribution that accumulates to the same retirement value under the entered 4% rate. Dividing that contribution by entered salary creates the salary-share view.
Worked example: three valuation dates and units
| Comparison view | calculator result | Appropriate use |
|---|---|---|
| Value at retirement | 163,083.92 | Compare the entered payment stream with a lump sum measured at the retirement date. |
| Present value today | 110,173.65 | Compare the same stream on today’s entered 4% discount basis. |
| Annual contribution equivalent | 13,583.41 | Compare with a hypothetical level annual contribution under the same entered rate. |
| Share of entered salary | 22.639% of 60,000 | Use this as a scale indicator, not as a required contribution or plan entitlement. |
Stress-test the rates and keep actuarial questions outside
Vary the discount rate, benefit growth, retirement timing and payment count separately. Each affects a different part of the timeline, so one headline value should not hide the range.
Formal defined-benefit valuation uses actuarial techniques and assumptions beyond this model. Mortality, survivor terms, vesting, funding, tax, transfer values and guarantees are excluded and require plan-specific evidence.
How the Pension Equivalent Value Calculator calculation works
presentValueToday = valueAtRetirement ÷ (1 + annualDiscountRate)^yearsUntilRetirement
- presentValueToday
- Present value today
- valueAtRetirement
- Value at retirement
- annualDiscountRate
- Annual discount rate
- yearsUntilRetirement
- Years until retirement
The calculator and article use this relationship consistently; the article does not reimplement the calculation.
valueAtRetirement = present value at retirement of the entered growing annual benefit stream
- valueAtRetirement
- Value at retirement
- firstAnnualBenefit
- First annual pension benefit
- paymentYears
- Payment years
- annualDiscountRate
- Annual discount rate
- annualBenefitGrowthRate
- Annual benefit growth
The calculator and article use this relationship consistently; the article does not reimplement the calculation.
equivalentAnnualContribution = valueAtRetirement ÷ future-value contribution factor
- equivalentAnnualContribution
- Equivalent annual contribution
- valueAtRetirement
- Value at retirement
The calculator and article use this relationship consistently; the article does not reimplement the calculation.
equivalentContributionShareOfSalary = equivalentAnnualContribution ÷ currentAnnualSalary

- Equivalent contribution share of salary
- equivalentAnnualContribution
- Equivalent annual contribution
- currentAnnualSalary
- Current annual salary

Value a 12,000 annual benefit for 20 years, starting in 10 years, at a 4% discount rate.
Inputs used in the Pension Equivalent Value Calculator worked example
| Input | Entered value | What it represents | Source class |
|---|---|---|---|
| First annual pension benefit | 12,000 currency units/year | Entered annual benefit at retirement. | user assumption |
| Payment years | 20 years | Whole years of assumed pension payments. | user assumption |
| Years until retirement | 10 years | Whole years until the first retirement value point. | user assumption |
| Annual discount rate | 0.04 decimal/year | Rate used to discount future values. | user assumption |
| Annual benefit growth | 0 decimal/year | Assumed annual growth in pension payments. | user assumption |
| Current annual salary | 60,000 currency units/year | Current salary used for contribution-share context. | user assumption |
Worked example: Pension Equivalent Value Calculator
The calculator normalizes the inputs above, applies Present value today, and returns the outputs below. The displayed result is therefore reproducible in the linked calculator.
| Measure | Result | Interpretation |
|---|---|---|
| Present value today | 110,173.65 currency units today | Retirement-date value discounted over years until retirement. |
| Value at retirement | 163,083.92 currency units at retirement | Present value at retirement of the entered benefit stream. |
| Equivalent annual contribution | 13,583.41 currency units/year | Annual contribution that reaches the retirement-date value under the entered discount rate. |
| Equivalent contribution share of salary | 0.23 share of current salary | Equivalent annual contribution divided by current salary. |
Interpret the result and test Annual discount rate
- Present value today: 110,173.65 currency units today. Retirement-date value discounted over years until retirement.
- Value at retirement: 163,083.92 currency units at retirement. Present value at retirement of the entered benefit stream.
- Equivalent annual contribution: 13,583.41 currency units/year. Annual contribution that reaches the retirement-date value under the entered discount rate.
- Equivalent contribution share of salary: 0.23 share of current salary. Equivalent annual contribution divided by current salary.
| Result | Baseline | Changed-input scenario | How to read it |
|---|---|---|---|
| Present value today | 110,173.65 currency units today | 91,808.59 currency units today | Retirement-date value discounted over years until retirement. |
| Value at retirement | 163,083.92 currency units at retirement | 149,546.52 currency units at retirement | Present value at retirement of the entered benefit stream. |
| Equivalent annual contribution | 13,583.41 currency units/year | 11,889.63 currency units/year | Annual contribution that reaches the retirement-date value under the entered discount rate. |
| Equivalent contribution share of salary | 0.23 share of current salary | 0.20 share of current salary | Equivalent annual contribution divided by current salary. |
