Machine-translated draft. If there is any difference between this translation and the English version, the English version prevails.
Optional. Personalises the totals and cost of waiting section below.
Starting values are illustrative placeholders, not Priimal figures and not benchmarks for any utility. Replace every value with your own. Costs are entered and shown in one currency; the tool does not convert between currencies.

1. Utility profile
Meter base & consumption
Total meters to read250,000
Reading frequency (cycles per year)12
Average consumption per meter (units/month)150
Tariff & staffing cost
Average tariff (per unit, local currency)0.12
Annual salary per field FTE (local currency)24,000
Annual billing resolution staff cost per FTE28,000
2. On-premises field collection
Field readers physically visit each site, record the meter reading manually or via a basic handheld device, and submit readings back to the billing system. Cost includes labour, supervision, and travel.

4. Billing errors from manual collection
Manual reading processes introduce transcription errors, missed reads estimated as zero, and data-entry mistakes. Each error consumes staff time to investigate and, if unresolved, results in direct revenue loss.
Error rate & resolution cost
Billing error rate (% of all manual reads)4.0%
Avg. staff hours to resolve one error2.0 hrs
Billing FTEs dedicated to error resolution5
Unresolved error rate (% of all errors)20%
Revenue loss per unresolved error (% of avg. monthly bill)40%
Customer churn from billing disputes (% of errors)3%

5. NTL / NRW losses
Non-technical losses (electricity theft, meter bypass, unmetered supply) and non-revenue water (physical and apparent losses) represent the largest single cost component. The recoverable pool is the share you assume could be addressed, so set it from your own records.
Loss rate & recovery potential
NTL / NRW rate (% of distributed volume)22%
Recoverable share of NTL / NRW (%, your assumption)50%

6. Connected alternative (retrofit reading device on NB-IoT connectivity)
This is the cost of replacing manual and self-service collection with a retrofit reading device on NB-IoT connectivity: a one-time device cost, amortised over its working life, plus an ongoing connectivity fee. Enter your own quotes or estimates below; no device or connectivity prices are built into this tool. Until you do, the comparison is not shown.

Methodology: figures assume the current manual collection mix and NTL or NRW rate hold steady over the delay period. Real costs and losses can move up or down. Every figure is an indicator based on your own inputs and requires verification.
