200 is the example result. Read it using the units and relationship stated below.

ROI (%) = (return − investment cost) ÷ investment cost × 100.
Purpose

Retention ROI uses return / benefit, investment / cost.

Separating growth, retention and subscription capacity

For retention roi, the relationship is ROI (%) = (return − investment cost) ÷ investment cost × 100. The amount depends on the supplied return / benefit, investment / cost, rather than a live market price or a value imported from another record. Recurring revenue should be compared across the same starting cohort. Expansion, contraction and churn change retention in different directions. Adding new customers to a retained-customer calculation can conceal losses in the original population.

Source and result record

For retention roi, retain Return / benefit, Investment / cost together with the output. Record the date of the source values and the unit convention used in the form. That record separates a change in the underlying case from a change in how the information was entered. A saved result without its source values cannot show which assumption produced it.

Example with the supplied inputs

Return / benefit: 15000; Investment / cost: 5000. Result: 200. The values are illustrative.

Compare one changed input

Return / benefit changes from 15000 to 16500. The result becomes 230. All other inputs remain fixed.

Calculation rule

Formula

ROI (%) = (return − investment cost) ÷ investment cost × 100.

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Return / benefit 15000 Use the source quantity represented by return / benefit. Keep the counted population fixed and avoid mixing a unit value with a period total.
Investment / cost 5000 Use investment / cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.

Output: 200 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather Return / benefit, Investment / cost. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Return / benefit on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 200.

Change Return / benefit from 15000 to 16500 while keeping every other value fixed. The result becomes 230. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
