Description
An annuity-due makes equal payments at the beginnings of successive periods.
An annuity-due makes equal payments at the beginnings of successive periods.1
This calculator includes a payment now when the count is positive, shifting the finite stream one period earlier than an annuity-immediate.
When to use Annuity Due Present Value Calculator
Use this tool to apply the stated annuity due present value calculator operation with an explicit input and unit basis.
How to use Annuity Due Present Value Calculator and how it works
- Establish the measurement basis and units described above.
- Enter actualEffectivePeriodInterest, actualPaymentCount, actualFirstPaymentAmount and run the tool.
- Read result.presentValue using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualEffectivePeriodInterest | Effective interest fraction for the payment period; greater than −1. | number | required; finite; further conditions in the algorithm |
| actualPaymentCount | Number of payments; integer 0–10,000. | number | required; finite; integer from 0 to 10000; further conditions in the algorithm |
| actualFirstPaymentAmount | Payment amount or progression base as explicitly defined by this tool’s algorithm. | number | required; finite; nonnegative; further conditions in the algorithm |
Require i>−1, nonnegative payment P and integer count 0–10,000. Sum P/(1+i)^k for k=0…n−1; zero count gives zero and n=1 returns P.
PV = sum from k=0 to n−1 of P/(1+i)^k Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.presentValue | Discounted payment-stream total in the input payment unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
