Manual Data Migration Costs: Include Cleanup, Mapping and Checking

By ProWorkstack · Editorial and development process

Budget manual data migration labor for record entry, cleanup, verification and fixed mapping work, with a separate contingency.

Open the manual data migration labor cost calculator to use your figures. The example amounts use one currency and are constructed scenarios, not industry benchmarks.

Measure a small representative sample

Moving a record is rarely just copying a row. Field mapping, inconsistent dates, missing identifiers and duplicate accounts can take longer than the transfer itself. Time a small sample that includes awkward records as well as easy ones. Keep the sample consistent with the population you intend to move.

Separate the routine transfer time from the extra cleanup time. If your measured transfer minutes already include cleanup, remove that cleanup from the separate estimate. Otherwise the same work is counted twice.

Build the hours from distinct tasks

Multiply all records by transfer minutes. Add affected records × cleanup minutes, then checked records × checking minutes. Divide total minutes by 60 and add fixed mapping and setup hours. Those fixed hours can include export preparation, field definitions and an initial test import.

The checking percentage is a plan you choose, not proof that a sample will catch every error. Important identifiers or balances may need complete reconciliation. If two record types need different treatment, calculate each type separately and add the resulting labor budgets.

Follow a worked budget

For 2,500 records, transfer time of 1.2 minutes contributes 50 hours. Cleaning 20% of records at four minutes each contributes 33.33 hours. Checking 10% at two minutes each contributes another 8.33 hours. Add 12 fixed hours for a base of 103.67.

A 15% contingency produces 119.22 budgeted hours. At a total hourly rate of 35, the labor budget is 4,172.58. This example uses unrounded values during calculation; rounding each intermediate line can create a small difference.

Keep the budget separate from the schedule

One hundred labor hours does not automatically mean one hundred elapsed hours. Access windows, dependencies, review availability and parallel work change the calendar. Build a separate schedule for cutover and sign-off.

List software fees, overlapping subscriptions, downtime and outside support separately. The calculator prices labor only. If the migration supports a software switch, carry this labor budget into that decision once, alongside the other setup costs.

Try your own scenario

Use the calculator, then change the assumption you are least confident about. Keep the reporting period and currency consistent. A currency selector changes formatting; it does not convert exchange rates.
