Customer Lifetime Value (CLV) Calculator

Estimate revenue lifetime value, gross-profit lifetime value, annual customer value, and optional LTV-to-CAC ratio.

What This Customer Lifetime Value (CLV) Calculator Calculates

Customer lifetime value estimates the economic value produced by an average customer over the expected relationship. This calculator shows both revenue lifetime value and a gross-profit version that applies the entered gross-margin percentage. An optional CAC input provides an LTV-to-CAC comparison using gross-profit CLV.

Formula and Method

Gross-profit CLV = average order value × purchases per year × customer lifetime × gross margin %.

Average order value is multiplied by annual purchase frequency to estimate annual customer revenue. That value is multiplied by average customer lifetime in years for revenue LTV. Applying gross margin converts revenue into an approximate gross-profit contribution before acquisition cost and other operating expenses.

How to Use the Calculator

1. Enter the measured dimensions, rates, costs, quantities, or other assumptions requested in the calculator.
2. Use matching units and a consistent reporting basis for related inputs.
3. Select Calculate and review the main result together with the supporting figures.
4. Compare the output with supplier information, drawings, contracts, or internal records before acting on it.
5. Use Copy Result, Share Result, or Save Result Image when you need a record of the calculation.

Worked Example

With an 85 average order value, six purchases per year, three years of average retention, and a 45% gross margin, revenue LTV is 1,530 and gross-profit CLV is 688.50. If CAC is 100, the gross-profit CLV-to-CAC ratio is about 6.89.

Common Uses

• Compare customer value with acquisition cost.
• Model how retention changes lifetime economics.
• See how gross margin affects the value of the same revenue stream.

How to Get a Better Estimate

Start with measurements or business records that match the scope of the calculation. Do not mix gross and net figures, nominal and actual dimensions, or values from different reporting periods unless the formula specifically calls for them. For physical material estimates, verify dimensions in the field and compare the result with product packaging or supplier data. For business calculations, use the same accounting period and currency basis for all inputs.

After calculating, change one assumption at a time. This sensitivity check is often more useful than relying on a single answer: it shows whether the result changes materially when waste, spacing, price, margin, time, or another uncertain input moves. Save or copy the result together with the inputs used so the estimate can be reproduced later.

How to Interpret the Result

Revenue LTV can overstate economic value when margins are low, so the gross-profit result is often more informative for planning. The LTV-to-CAC ratio is a simple benchmark, not a universal target; cash timing, payback period, churn risk, overhead, and capital constraints also matter.

Using the Result in Real Work

OfficeCalculator.Net is designed to make the arithmetic clear, but the number on screen is only as reliable as the measurements, rates, and assumptions entered. Before ordering materials, issuing a quotation, charging a fee, or making a commercial decision, compare the result with drawings, contracts, supplier data, manufacturer instructions, or your organization’s approved method. Rounding is shown deliberately when whole packages, stock pieces, or discrete items are required.

Important Notes and Limitations

This simplified model assumes stable order value, purchase frequency, margin, and average lifetime. It does not discount future cash flows, model cohort retention curves, refunds, support cost, cost-to-serve, expansion revenue, churn timing, or changes in customer behavior.

Calculator results are for planning, checking, learning, and general informational use. Keep original measurements, supplier documentation, drawings, contracts, or accounting records when a decision needs independent verification. No value entered into this calculator is intentionally sent to OfficeCalculator.Net for server-side calculation.

Frequently Asked Questions

Why show gross-profit CLV instead of only revenue LTV?

Gross-profit CLV reflects the margin left after cost of goods rather than treating all revenue as economic value.

What if I do not know CAC?

Enter 0; the calculator will still report revenue and gross-profit lifetime value.

Does this model discount future years?

No. It is a simple undiscounted planning model.
