Is the investment worth it? ROI and payback for owners
A business ROI calculator: owners enter an investment, its net annual return and a holding period to see ROI, total return, payback period and annualized return.
Included on every plan, even the free Practitioner plan. No card needed.
How do you calculate return on investment for a business project?
Multiply the net annual return by the holding period, divide by the investment, and express it as a percentage. $25,000 a year for five years on $100,000 is a 125% ROI with a four-year payback. The annualized figure, about 17.6%, is the fairer way to compare projects of different lengths.
Before buying equipment, software or a marketing program
Owners weighing a purchase, a new hire or a marketing spend want a quick sense of the return. Vendors quote optimistic ROIs; owners want to check them.

What lands in your inbox
When a client asks your firm to review the result, the request arrives as a contact record with their inputs and results attached, by email and, on paid plans, by webhook to your CRM.
Received
Investment, annual return and period show the scale and expected payoff. Very short paybacks may reflect optimistic assumptions; large investments may need financing and tax planning.
ROI versus annualized ROI
Return on Investment and Total Return show the overall result. Payback Period shows how long it takes to recover the investment. Annualized ROI (CAGR) converts the total into a yearly rate.
ROI over long periods looks large; annualized ROI makes projects comparable.
Results shown: Return on Investment · Total Return · Payback Period · Annualized ROI (CAGR).
$100,000 returning $25,000 a year
Over five years: $125,000 total return, 125% ROI, payback in $100,000 ÷ $25,000 = 4 years. Annualized, a 125% total return over five years is roughly 17.6% a year.
Why ROI questions suit fractional CFOs and CPAs
Capital decisions shape a business for years, and tax treatment changes the return. A firm that helps owners evaluate projects becomes part of strategy.
The request shows the size of the investment and the owner's expectations, which you can test.

Terms your client sees in the calculator
These definitions appear in the calculator's collapsible Definitions block, so clients don't have to call to ask what a label means.
- Return on investment (ROI)
- Total return divided by the initial investment, as a percentage. In this calculator it is the net annual return times the holding period, over the amount invested, so $25,000 a year for five years on $100,000 is 125%. ROI ignores timing, so it cannot tell a fast return from a slow one.
- Initial investment
- The total amount put in at the start: purchase price, equipment, setup, training and any working capital the project ties up. Leaving out startup costs overstates ROI and shortens the payback period. The calculator assumes this amount is recovered in addition to the net annual return.
- Net annual return
- The profit the investment produces each year after its own operating costs, on top of getting the original investment back. It should reflect added revenue or cost savings net of new expenses. This calculator holds it constant for every year, which real projects rarely do.
- Total return
- The net annual return multiplied by the number of years held: the cumulative profit over the holding period, not counting recovery of the initial investment. It is the numerator of the ROI figure. It is not discounted, so a dollar earned in year five counts the same as one earned in year one.
- Payback period
- How long it takes for cumulative returns to equal the initial investment: the investment divided by the net annual return. A $100,000 investment returning $25,000 a year pays back in four years. It is a simple risk check; it ignores returns after payback and the time value of money.
- Annualized ROI (CAGR)
- The compound annual growth rate that would turn the initial investment into the investment plus total return over the holding period. It converts a multi-year ROI into a yearly rate that can be compared with other investments or a loan rate. A 125% return over five years annualizes to roughly 17.6%.

What about depreciation?
It affects taxes and accounting profit, not modeled here.
How do I compare projects of different lengths?
Use annualized ROI or IRR.
Can I include a resale value?
Use the IRR calculator for that.
Is the return guaranteed?
No, it's an estimate.
Which plan includes it?
Every plan, including the free Practitioner plan, which runs up to 5 calculators at once alongside the other business tools. Firm (up to 50) and Network (no cap) add webhooks and white-label. See pricing.
