How this calculator helps

Translate a return rate into affected orders, refunded revenue and operational loss. Enter a per-return unrecoverable amount for shipping, handling, fees, damage or markdown that is not recovered.

How to use it

  1. 1

    Use orders from a mature return cohort.

  2. 2

    Enter net AOV for the same cohort.

  3. 3

    Add the confirmed return or refund percentage.

  4. 4

    Estimate unrecoverable expense per returned order.

ƒ

Formula and methodology

Returned orders = total orders × return rate. Refunded revenue = returned orders × AOV. Total impact adds unrecoverable cost per return.

The calculator applies the displayed arithmetic to the values entered on this device. It does not silently load a local tax rate, currency conversion or commercial assumption.

Worked calculation example

From 1,000 orders at 70 AOV and an 8% return rate, about 80 orders and 5,600 revenue are refunded before adding return-handling losses.

How to interpret your result

Estimate revenue lost to returned orders, retained revenue and unrecoverable return costs from an e-commerce period. Read the main result together with the supporting values rather than treating one number as a guarantee. The disclosed method is: Returned orders = total orders × return rate. Refunded revenue = returned orders × AOV. Total impact adds unrecoverable cost per return.

Input guide

1

Use orders from a mature return cohort.

2

Enter net AOV for the same cohort.

3

Add the confirmed return or refund percentage.

Common mistakes to avoid

  • Ignoring cohort maturity: Recent orders understate returns until the allowed window has passed.
  • Overlooking recovery: Restockable products and retained shipping charges reduce the final loss.
  • Failing to test reason mix: Sizing, damage, fraud and customer remorse require different remedies.
How to verify this result

Repeat the calculation with verified measurements and check any decision-specific rule with the responsible provider or professional.

Understanding the displayed figures

The main result answers the page’s primary question, while the supporting figures reveal how that answer was formed. Read the labels carefully before comparing alternatives. A percentage can describe a rate, a share of income, a fee or a change over time; those meanings are not interchangeable. Monetary fields are deliberately currency-neutral, so use one currency throughout the calculation and convert external figures before entering them.

Dates, balances and rates should come from the same measurement period. When an annual rate is combined with monthly payments, the calculator converts the rate to the relevant periodic basis described in the methodology. Displayed values are rounded for readability, but calculations retain additional precision. Small differences from a provider statement can result from daily accrual, transaction timing or the provider’s rounding convention.

Planning with multiple scenarios

Start with values that best describe the current situation and keep that result as the baseline. Next, change only one uncertain input—such as a rate, payment, fee, return or time period—and calculate again. This makes the source of the difference visible. A cautious scenario is generally more informative than increasing several favourable assumptions at once.

Do not interpret a favourable estimate as approval, eligibility or a forecast. The calculator cannot know future market conditions, personal risk tolerance, contractual exceptions or rules that apply in a particular jurisdiction. When comparing products, use equivalent periods and include charges that are collected outside the headline rate.

What can affect the result?

Cohort maturity

Recent orders understate returns until the allowed window has passed.

Recovery

Restockable products and retained shipping charges reduce the final loss.

Reason mix

Sizing, damage, fraud and customer remorse require different remedies.

Privacy and browser processing

Values entered on this page are processed in the current browser session. SolvePilot does not require an account and does not receive the values entered into the calculator. Refreshing or closing the page clears the working values unless the browser itself restores a previous session. Avoid entering identifying or account information because the calculation needs summary values only.

Accuracy and verification

Accuracy depends first on input quality. Confirm definitions, scales, dates and source information before entering a value. Keep an independent record of any result used for planning because this page does not create an official statement or retain a calculation history.

Limits of this estimate

This average model does not track exchanges, partial refunds, resale recovery, tax adjustments or product-specific return patterns.

Important: Treat the result as a planning estimate. Confirm official requirements and consequential decisions with the relevant institution, authority or qualified professional.
