Accounting Startup Cost Calculator
Estimate the upfront and early operating costs of starting an accounting business, including a contingency allowance.
Overview
This Accounting Startup Cost Calculator estimates the funding needed to launch an accounting practice or bookkeeping business. Add your one-time setup expenses, expected monthly operating costs, planned cash runway and a contingency allowance to create a clearer startup budget.
How it works
The calculator adds your one-time setup expenses first. It then multiplies your estimated monthly operating costs by the number of runway months selected. A contingency percentage is applied to this combined amount, and the result is added to produce the estimated startup funding requirement. This approach helps separate immediate launch costs from the cash needed to operate while the client base is developing.

Frequently asked questions
What costs should I include when starting an accounting business?
Include registration and licence fees, insurance, software, computers, office setup, website and marketing costs, plus recurring expenses such as rent, subscriptions, payroll and utilities.
How many months of operating runway should I budget for?
The appropriate runway depends on your expected client acquisition pace, personal financial position and fixed costs. Many new businesses model several months of costs to account for a gradual build-up in revenue.
Should I include my own salary in monthly operating costs?
If the business needs to support owner drawings or a salary before revenue is stable, include that amount in monthly operating costs so the funding estimate reflects the cash required.
Why add a contingency to startup costs?
A contingency provides a buffer for costs that are higher than expected or were missed during initial planning, such as extra software, legal work, repairs or additional marketing.
Does this calculator include tax or financing costs?
No. It uses the amounts you enter and does not estimate taxes, loan interest, banking charges or other financing costs unless you include them in one of the cost fields.
