ROI is return on investment. It measures profit relative to initial investment as a percentage.

How do you annualize ROI?

Annualized ROI converts total return over multiple years into an equivalent yearly compounded rate.

Yes. If final value is lower than your initial investment, profit and ROI are negative.

How to use this calculator for a real decision

Enter the amount invested and the net profit or return generated to see the return on investment as a percentage. Use it to evaluate marketing campaigns, equipment purchases, software subscriptions, or any business expense. Compare different investments side by side: a $5,000 marketing campaign that generates $15,000 in sales (200% ROI) beats a $10,000 tool that saves $12,000/year (20% ROI). The calculator helps you prioritize spending on what actually moves the needle.

Worked example

A contractor spends $3,000 on Google Ads for a month and gets $9,000 in new contracts directly attributed to those ads. ROI: ($9,000 - $3,000)/$3,000 = 200%. That means every dollar spent returned $3. If the same contractor spends $8,000 on a new truck that helps complete jobs 15% faster ($12,000/year extra revenue), ROI is ($12,000 - $8,000)/$8,000 = 50% in the first year. Year 2 ROI jumps since the truck is already paid for.

Common mistakes to avoid

Ignoring time period: A 100% ROI over 1 year is different from 100% over 5 years. Annualize returns to compare apples to apples.

Forgetting ongoing costs: A piece of equipment costs more than the purchase price. Factor in maintenance, training, software, and operational costs.

Attribution errors: Was that sales increase from the marketing campaign or from seasonal demand? Use control periods to isolate the investment effect.

Only measuring financial returns: Some investments (training, branding, security) have non-financial benefits. Consider them even if ROI looks low.

Key terminology

Net profittotal returns minus total costs associated with the investment

Annualized ROIROI adjusted to a one-year period, useful for comparing investments of different durations

Payback periodthe time required for an investment to generate enough returns to cover its cost

Opportunity costthe return you could have earned by investing the same money elsewhere

Frequently asked questions

What is a good ROI?

For business investments, 50-200% ROI within the first year is strong. Stock market average is 7-10% annually. Context matters heavily.

How do I calculate ROI over multiple years?

Calculate total returns over the full period, then annualize. The calculator handles single-period ROI. For multi-year, sum up all returns vs total cost.

What if my investment has no direct monetary return?

Not all value is financial. Customer satisfaction, employee retention, and brand strength have real but hard-to-measure ROI. Consider them qualitatively.

Is a negative ROI always bad?

Not necessarily. Strategic investments like R&D, training, or brand-building may have short-term negative ROI but long-term strategic value.
