Build a Ready-to-Use BaaS Financial Projection in Excel

The Battery as a Service Financial Model Template is a detailed, ready-to-use Excel model for forecasting an EV battery subscription, battery swapping and charging business. Developed by Excel Business Resource, this model helps founders, investors, consultants and financial analysts build a detailed 10-year financial forecast based on real operating drivers.

Unlike a simple battery-swapping calculator, this BaaS Financial Forecasting Model Excel connects customers, subscriptions, battery swaps, battery requirements, battery CAPEX, charging revenue, operating costs, Solar PV, BESS and second-life batteries with integrated financial statements and valuation.

What Can You Forecast With This Battery Swapping Financial Model?

The model uses driver-based assumptions rather than simply applying revenue growth percentages. You can customize:

Customer segments, starting subscribers, monthly growth and churn
Monthly subscription pricing, swap fees and overage charges
Batteries allocated per subscriber
Average battery swaps per day
Battery type, useful life and total life cycles
Battery cost and State of Health (SOH)
Retired battery resale/recycling value
Battery insurance and IoT costs
Electricity, maintenance and field-operation costs
Per-user and percentage-of-revenue costs
Walk-in charging customers, charging capacity and pricing
BAAS operating CAPEX and battery replacement requirements
Headcount and salaries
Debt, financing and one-time project costs

This makes it a practical EV Battery Swapping Financial Projection Spreadsheet for testing different business models, pricing strategies and operating scenarios.

Does the Model Include Solar, BESS & Second-Life Batteries?

Yes — and this is one of its key differentiators.

The model goes beyond a traditional Battery Swapping Station Financial Model by including an integrated Solar + BESS energy planning framework.

You can model:

Solar PV capacity and generation
Solar performance ratio and degradation
Daylight and nighttime charging demand
BESS storage capacity
BESS round-trip efficiency
Battery degradation
Depth of discharge
Peak and off-peak electricity tariffs
Energy dispatch
Grid electricity requirements
Solar and BESS CAPEX
BESS depreciation

It also allows retired EV fleet batteries to be considered for second-life BESS applications, including SOH at transfer, remaining depreciation period, net battery value and eventual salvage value.

This makes the model particularly useful for businesses combining Battery as a Service, EV charging, Solar and BESS.

What Revenue Streams Are Included?

The Battery Subscription & Swap Revenue Model includes multiple revenue drivers:

Battery subscription revenue
Battery swapping revenue
Overage swap revenue
Walk-in charging revenue from non-subscribers
Retired battery resale/recycling value
Potential Solar/BESS-related savings and economics

The separate charging station schedule allows you to forecast charging fleet volume, monthly growth, price per fleet charged and maximum daily charging capacity.

Monthly Income Statement
Monthly Cash Flow Statement
Monthly Balance Sheet
