    What is an
    install worth?

    A mobile app LTV calculator.
    One cohort. A clear view of what it earned.

    Your cohort

    Hypothetical example · All amounts are totals for this cohort.

    Use cumulative totals from day 0 through day 90. Changing the window or currency only changes the labels; it does not forecast revenue or convert amounts.

    Include non-payers. Use the users attributable to the acquisition spend below.

    After refunds, store fees, and applicable transaction taxes. Enter 0 for an ads-only app.

    Revenue from this cohort, after applicable deductions. Enter 0 if you do not show ads.

    Costs attributable to serving these users, such as AI inference or usage-based hosting.

    Media spend, plus any attributable creative or agency costs you want to include.

    D90 · Realized net LTV / install

    $3.00

    Net purchase proceeds + net ad revenue,
    divided by every install in the cohort.

    After variable service costs
    $2.60
    Acquisition cost / install
    $1.80
    Left after acquisition / install
    $0.80

    This cohort has covered the acquisition spend entered by D90.

    $800.00 remaining across the cohort after the costs entered. This is before fixed overhead and profit taxes, and excludes activity after D90.

    Know what you are measuring

    A snapshot, with the assumptions in view.

    Keep one population.

    Use a fixed acquisition cohort that has reached the selected age. Do not mix a paid cohort’s spend with proceeds from all users.

    Keep the deductions consistent.

    Enter proceeds after fees, refunds, and applicable transaction taxes. Subtract service costs separately. Net revenue can be negative after adjustments.

    Keep the time window honest.

    This measures observed value through D90. It does not predict lifetime revenue, the exact payback day, or when a store will pay you.
