THE NUMBERS, EXPLAINED
How to use this calculator.
Fixed-width suffix, all symbol combinations allowed, leading zero allowed and unique date prefix for each stated day; prefixes are supplied counts, not calendar parsing.
Start with your inputs
Enter alphabet symbols per batch-code character, characters in daily batch suffix, expected batches per day, distinct date-prefix values. Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Alphabet symbols per batch-code character | 10 |
| Characters in daily batch suffix | 3 |
| Expected batches per day | 100 |
| Distinct date-prefix values | 365 |
A worked example
With the example inputs above, codes available per date is 1,000. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Codes available per date | 1,000 |
| Total unique codes in date range | 365,000 |
| Unused daily suffixes | 900 |
| Daily capacity utilization (%) | 10 |
How this is calculated
Codes available per date
Raise alphabet size to fixed suffix length.
Total unique codes in date range
Multiply daily suffix capacity by distinct date prefixes.
Unused daily suffixes
Subtract daily batches from suffix capacity.
Daily capacity utilization (%)
Compare daily batch count with suffix space.
Symbols and units
- a
- Alphabet symbols per batch-code character
- b
- Characters in daily batch suffix
- c
- Expected batches per day
- d
- Distinct date-prefix values
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Fixed-width suffix, all symbol combinations allowed, leading zero allowed and unique date prefix for each stated day; prefixes are supplied counts, not calendar parsing.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Codes available per date; Total unique codes in date range; Unused daily suffixes; Daily capacity utilization (%). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Fixed-width suffix, all symbol combinations allowed, leading zero allowed and unique date prefix for each stated day; prefixes are supplied counts, not calendar parsing.
Are my inputs stored or sent to AI?
