Compare complete paper, mail, and in-person contract cost with electronic-contract implementation, recurring fees, time savings, completion value, NPV, ROI, payback, and volume thresholds.
Every displayed value is an illustrative scenario, not a product average or guaranteed outcome. Replace it with a measured contract sample and current vendor quotes.
Separate workflows with different pages, signers, cycle time, abandonment, and cash value to avoid a misleading average.

Use attempts entering the signature workflow, not completed contracts.
Signer count used for mailing and authentication charges.
Use zero for workflows without a collection event.
Use contribution, not full revenue, for one incremental completion.
Purchase, supply, and service-procurement workflows.
Use attempts entering the signature workflow, not completed contracts.

Saved time is not an automatic headcount or cash reduction. Validate completion and cycle-time changes on matched workflow samples, and value incremental completions with contribution rather than full revenue.
Legal and method sources checked 2026-08-12. Korean electronic-document and signature rules are jurisdictional review boundaries only; validate each contract type, identity method, retention, evidence, privacy, tax, accounting, and vendor requirement separately.
This calculator compares the complete paper, mail, and in-person contract workflow with a mixed electronic-contract workflow.
It combines contract volume, pages, signers, printing, postage, travel, storage, preparation, follow-up, and rework with platform, transaction, identity-check, API, archive, administration, and implementation costs.
The model also keeps operational savings separate from commercial benefits.
Recovered contracts use contribution profit rather than total revenue, while earlier cash uses only the time value of cash that would have arrived under either workflow.
A sales contract may connect contract completion to cash collection and contribution profit, while a procurement or HR document often does not create revenue in the same way.
Combining every document into one average can hide the printing burden of a long procurement agreement, the authentication cost of a multi-signer document, or the timing value of a sales contract.
Enter attempted monthly volume, expected cash per completed contract, and contribution profit to model cycle-time and completion-rate benefits conservatively.
Focus on pages, signers, mail, travel, approval delay, and staff time, and leave commercial-benefit inputs at zero when no cash receipt is involved.
Model employment, consent, delegation, and policy documents through handling, exception, rework, and archive costs without inventing a revenue benefit.
| Input group | Recommended evidence | Double-counting check |
|---|---|---|
| Volume, pages, and signers | Four to eight weeks of send logs and completed-document samples | Use attempts entering the signature workflow, not completed documents |
| Print, mail, travel, and storage | Invoices, courier records, expense claims, and archive bills | Exclude employee time already embedded in a travel charge |
| Preparation, tracking, and rework | Observed work samples, time records, and exception logs | Define non-overlapping start and end points for each task |
| Electronic pricing | Current quote, order form, contract, and usage report | Confirm whether pricing is per send, completion, signer, identity check, API call, or stored item |
| Cycle time and abandonment | Comparable before-and-after cohorts from the same contract group | Reduce attribution when price, channel, owner, or contract terms also changed |
| Cash and contribution profit | Payment terms, receipt dates, and contribution-margin records | Use timing value for earlier cash and contribution profit for recovered contracts |
Print cost equals pages multiplied by copy sets and cost per page.
The model adds postage per signer, trips multiplied by cost per trip, archive cost, and the labor value of preparation, tracking, and expected rework minutes.
Electronic cost adds the transaction fee, signer identity cost, API cost, archive cost, other per-contract charges, and electronic-workflow labor.
Monthly platform and administration costs remain fixed, so the allocated cost per electronic contract can rise when adoption or volume is low.
Paper-only TCO assumes every attempted contract stays in the paper or in-person workflow.
Hybrid TCO combines the remaining paper volume, electronic variable costs, fixed platform and administration costs, and net initial investment.
Completion and earlier-cash benefits stay outside operating TCO so that a commercial assumption cannot disguise a high process cost.
A drop from 6% paper abandonment to 3% electronic abandonment does not prove that the system caused the full three-percentage-point difference.
The calculator applies the user-entered attribution rate and multiplies recovered completions by contribution profit, not revenue.
Receiving $10,000 three days earlier does not create a $10,000 benefit.
The model multiplies common completed volume by cash per completion, days saved divided by 365, annual cost of funds, realization, and adoption.
Incremental completions are excluded from that common-volume base because their contribution profit is already counted separately.
Fewer minutes do not automatically produce headcount reduction or cash savings.
Confirm whether the released capacity changes throughput, overtime, outsourcing, response time, rework, or another measurable outcome, then reduce the labor value when evidence is weak.
The English defaults are an independent USD illustration, not a currency conversion of the Korean example and not a market benchmark.
Replace every price, labor rate, volume, delay, adoption, completion, and cash assumption with internal records and current vendor terms.
Compare paper-only monthly cost, target hybrid cost, workflow savings, recovered-completion benefit, earlier-cash value, and steady-state net benefit.
Use nominal and present-value benefit, program cost, NPV, ROI, first payback, sustained payback, and discounted payback across the selected horizon.
Review monthly hours released, completion-equivalent contracts recovered, and cycle days saved separately from the cash result.
Separate steady-state operating break-even volume from the volume needed to reach discounted NPV zero by the target month.
A useful pilot compares similar contract groups, values, counterparties, and owner experience instead of comparing two unrelated calendar months.
Capture send time, first open, completion, exception, resend, abandonment reason, payment date, and staff handling time with the same definitions in both workflows.
The Korean Framework Act on Electronic Documents and Transactions was checked through the official law API on August 12, 2026.
Article 4 states the general rule that legal effect cannot be denied solely because a document is electronic, while Article 4-2 addresses viewability and reproducible preservation for writing requirements and preserves exceptions under other laws or the nature of the document.
Article 5 addresses conditions for electronic preservation, including information needed to identify the writer, recipient, and transmission or receipt timing.
Article 3 of Korea’s Electronic Signature Act provides that effect cannot be denied solely because a signature is electronic and addresses signatures selected under law or party agreement.
These general rules do not automatically satisfy contract-specific identity, authority, explanation, delivery, notarization, face-to-face, original-document, retention, evidence, or special-law requirements.
The calculator does not score legal validity and leaves authentication, evidence, archive, export, and legal-review cost for the user to verify and enter.
The sensitivity table lowers paper direct-cost savings, labor savings, or commercial benefits, raises vendor cost, and combines adverse assumptions by the percentage you enter.
That percentage is not a confidence interval, so replace it with quote uncertainty, pilot variance, or a procurement-approved range.
Include vendor setup, templates, integration, training, legal and security review, internal requirements, testing, migration, change management, and pilot labor. Keep subscription and transaction charges in recurring cost.
No. Use only the timing value for cash on contracts completed in both workflows. Apply attribution and contribution profit, not revenue, to contracts recovered from the abandonment-rate difference.
Set paper and electronic abandonment equal or set contribution profit to zero. Test whether verified process savings alone support the decision, then update the model after a comparable pilot.
The model conservatively charges monthly platform and administration cost from month one. Adjust the inputs when a free pilot or later billing start is documented in the contract.
Operating break-even covers recurring fixed cost at steady-state adoption. Target-payback volume includes initial cost, delay, ramp, escalation, discounting, and the selected target month.
No. General electronic-document and signature rules coexist with contract-specific special rules, agreed signature methods, identity and authority controls, delivery, explanation, notarization, face-to-face, original, and retention requirements.
Both interfaces use the same pure calculation engine, but the examples are independent. The Korean page uses a KRW illustration and the English page uses a USD illustration, so parity should be tested with identical inputs.
Current status and relevant articles of the Korean laws were checked through the official National Law Information Center API on August 12, 2026.
The present-value, complete-cost, assumption, and sensitivity structure also draws on NIST Handbook 135e2022 and GAO-20-195G without importing their asset lives, prices, or discount rates into this contract model.
Start with abandonment and cash benefits at zero, confirm the process-cost baseline, and add only benefits supported by pilot evidence.
Use the base, single-downside, and combined-downside results together before choosing a vendor or pilot scope.
Results are planning estimates, not investment, legal, tax, accounting, privacy, or security advice.
