ROI Calculator

Calculates roi from initial investment, final value, income received. Defaults are filled in so you can review a working example before changing inputs.

USD

Original amount invested or project cost before additional costs.

USD

Current or ending value before adding separate income received.

USD

Dividends, interest, rent, coupons, or other income already received.

USD

Fees, commissions, repairs, or other user-provided costs to include.

What the result means

ROI is the number to carry forward from this ROI calculation. Net return divided by total cost. Read the projected value or rate first, then use contribution, period, and return outputs to explain why it changed. Use net return, total cost, and total proceeds to explain why ROI moved when an input changed. Change one assumption at a time so you can see which input is driving the projection. Check nominal versus effective rate, contribution timing, compounding frequency, inflation, fees, and tax treatment before treating the result as final.

ROINet return divided by total cost.
Net returnTotal proceeds minus total cost.
Total costInitial investment plus additional costs.
Total proceedsFinal value plus income received.

Use the result this way

  1. Start with ROI, then use supporting outputs only to explain the primary answer.
  2. Verify initial investment, final value, and income received before copying the result.
  3. Keep units consistent with the labels shown in the form, stay within the documented minimum and maximum ranges, and enter percentages as whole percents, such as 6.5 for 6.5%, unless a field says otherwise.
  4. Change one assumption at a time so you can see which input is driving the projection.

How to use this calculator

Use ROI Calculator when you need roi, then use net return and total cost to check the context for planning conversations, quote comparisons, payment checks, and scenario review.

Best for

  • Comparing one financial scenario with another
  • Preparing questions for a lender, advisor, or statement review
  • Reviewing a default example before entering your own initial investment and final value.

Check before relying

  • Verify rates, fees, timing, taxes, and local rules against official documents before acting.
  • All input amounts use the same currency.
  • Additional income and costs are user-provided and non-negative.
  • Source context: OpenStax, reviewed 2026-05-26.

Formula

ROI = (final value + income received - initial investment - additional costs) / (initial investment + additional costs) x 100. Key assumptions: All input amounts use the same currency. Additional income and costs are user-provided and non-negative. ROI is not annualized and does not account for time, volatility, taxes, inflation, financing costs, or opportunity cost.

  • ROI = (final value + income received - initial investment - additional costs) / (initial investment + additional costs) x 100.
  • All input amounts use the same currency.
  • Additional income and costs are user-provided and non-negative.
  • Primary source context: OpenStax.

Inputs

Enter initial investment, final value, income received, and additional costs for planning conversations, scenario checks, and lender or statement comparison. Before calculating, keep units consistent with the labels shown in the form, stay within the documented minimum and maximum ranges, and enter percentages as whole percents, such as 6.5 for 6.5%, unless a field says otherwise. Initial investment: Original amount invested or project cost before additional costs. Final value: Current or ending value before adding separate income received. Income received: Dividends, interest, rent, coupons, or other income already received.

Example

Using the default inputs, ROI Calculator returns ROI of 26.829268%. Adjust initial investment, final value, income received, and additional costs to match your own scenario.

FAQ

How is ROI calculated here?

ROI = (final value + income received - initial investment - additional costs) / (initial investment + additional costs) x 100. The first assumption to check is: All input amounts use the same currency.

What does ROI mean for ROI?

Read the projected value or rate first, then use contribution, period, and return outputs to explain why it changed. Secondary values such as net return, total cost, and total proceeds are there to explain the primary answer, not to replace it.

What should I enter for Initial investment?

Original amount invested or project cost before additional costs. Use USD for this field. Keep units consistent with the labels shown in the form, stay within the documented minimum and maximum ranges, and enter percentages as whole percents, such as 6.5 for 6.5%, unless a field says otherwise.

How does Final value change ROI?

Current or ending value before adding separate income received. Changing it can alter ROI because the formula uses the submitted inputs together. Also compare nominal versus effective rate, contribution timing, compounding frequency, inflation, fees, and tax treatment.

Why does the ROI example show 26.829268% for ROI?

The default inputs produce 26.829268% for ROI. Treat that as a format and scale check, then replace every default value with your own inputs.

Can the ROI result replace financial advice?

No. Use the ROI result as comparison context only. Market returns, taxes, fees, legal terms, and personal constraints can change the real outcome.
