How the math works

Packages/SF/day = daily packages ÷ sqft. Revenue/SF/yr = packages × revenue × 365 ÷ sqft.

900k / 150k = 6 pkg/SF/day. × $45 × 365 / 150k = $98,550/SF/yr revenue. 2% rent cap = $1,971/SF.

How this calculator works

What this page estimates

This Ecom Shipping Ratio Calculator is built to give a quick, browser-based estimate for ecom shipping ratio. E-commerce throughput per sqft drives tenant rent capacity. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the ecom shipping ratio result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this ecom shipping ratio estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Why is this ratio important?

Tenant rent capacity is directly tied to revenue per sqft generated. High-throughput e-commerce (6-15 packages per sqft per day) generates more revenue per sqft than low-throughput warehouse (0.5-2 packages per sqft per day). Tenant can afford higher rent. Landlord can extract more rent. Building design (clear height, dock density) affects feasible throughput — design matters for tenant selection.

Ratio by operation type?

Traditional retail warehouse: 0.5-2 packages/SF/day. Regional distribution center: 3-6 packages/SF/day. E-commerce fulfillment (Amazon, FedEx): 8-15 packages/SF/day. Micro-fulfillment (robotic, dense urban): 15-30 packages/SF/day. Dark grocery: 5-10 orders/SF/day. Meal kit: 8-15 shipments/SF/day. Rent capacity scales roughly with throughput; premium operations pay 2-5x base warehouse rent.

What drives throughput?

(1) Automation (AS/RS, goods-to-person, robotic). 40-60% throughput increase. (2) Clear height (more vertical storage). 20-30% increase. (3) Dock doors (more parallel truck activity). 10-20% increase. (4) Labor density (picker per sqft). 15-30% increase. (5) WMS software (route optimization). 10-20% increase. Stack these = 2-3x throughput improvement on legacy facility.

Rent-to-revenue economics?

E-commerce target: rent at 1.5-3% of gross revenue. $300/SF gross revenue × 2% = $6/SF rent — too low for prime markets. $600/SF × 2% = $12/SF — in line with secondary markets. $1200/SF × 2% = $24/SF — primary e-commerce markets. Micro-fulfillment achieves $2000+/SF revenue — supports $40-60/SF rent. Match tenant operation type to building rent capacity.
