How to Read Your Results
One-time startup costs represent expenses expected to be paid to establish or launch the business.
Operating runway is the cash set aside for recurring costs during the selected number of months.
The contingency amount is a planning buffer, not a quote or guaranteed amount.
The total funding estimate does not reduce costs by expected sales or client receipts.
Compare scenarios using the same currency and ensure recurring costs are entered on a monthly basis.
Assumptions & Important Notes
- Each example assumes monthly operating costs remain constant for the runway period.
- The examples do not subtract revenue received after launch.
- Contingency is calculated from both one-time costs and runway costs.
- The examples are planning illustrations rather than financial advice.

Frequently Asked Questions
Can I use these examples for a bookkeeping business?
Yes. Replace the example costs with your own software, equipment, insurance, marketing and monthly operating estimates.
Why does a longer runway increase the total so much?
Every extra month adds another full month of recurring operating costs, and it also increases the contingency amount.
Can a home-based firm have office setup costs?
Yes. Home-based setup may still include furniture, devices, connectivity, security or a home-office deposit where relevant.
How can I compare a lean and office-based launch?
Create one calculation for each cost structure using the same runway and contingency assumptions, then compare their total funding estimates.
