Accountants Project Quote (Hourly) Calculator
Estimate an accountant's project quote from expected billable hours, hourly rate, expenses, contingency, and applicable tax.
Overview
Use this Accountants Project Quote (Hourly) Calculator to build an estimated project fee from anticipated billable hours, your hourly rate, expected expenses, a contingency allowance, and any applicable sales tax or VAT. It is useful for preparing a clear initial quote while keeping the underlying time estimate visible.
How it works
The calculator multiplies estimated billable hours by the hourly rate to calculate professional fees. It then adds a contingency amount based on that fee and adds estimated expenses. Sales tax or VAT is calculated from the resulting pre-tax quote. The total project quote is the pre-tax amount plus tax. The effective hourly quote rate shows the full quoted total divided by the estimated hours, so it reflects the effect of expenses, contingency, and tax.

Frequently asked questions
How do I calculate an hourly project quote for accounting work?
Estimate the time required, multiply it by your hourly rate, add expected expenses and an allowance for uncertainty, then add any applicable tax.
What should be included in estimated billable hours?
Include planning, client meetings, document review, analysis, preparation, quality checks, revisions, and communication that you intend to bill for.
Should I add a contingency to an accountant's project quote?
A contingency can help account for incomplete records, changing scope, extra queries, or revisions. The appropriate amount depends on how well defined the engagement is.
Are expenses included in the hourly rate?
They can be, but this calculator shows them separately so expected filing fees, software charges, travel, and third-party costs can be included clearly.
Does this calculator create a fixed-fee quote?
It estimates a project total using an hourly basis. Whether the amount is presented as a fixed fee, capped fee, or time-based estimate depends on the engagement terms.
Should sales tax or VAT be included in the quote?
Enter the applicable rate if tax should be charged. It is often helpful to show the pre-tax fee and tax amount separately on a client quote or invoice.
