Green/ESG investing has grown significantly. Performance broadly comparable to broad market indices over long periods. Use any return rate matching specific fund history. Compound growth math identical to standard investing.
Run it with sensible defaults
Using initial investment of 5,000, monthly contribution of 200, annual return of 7%, years of 15, the calculation works out to 77,637.19. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Initial Investment, Monthly Contribution, Annual Return, and Years — do not pull with equal force. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
How the math works
Standard compound interest with monthly contributions. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Cost vs value in green choices
Sustainable options usually cost more upfront and less over time. This tool separates the two so the comparison is fair — looking at purchase price alone consistently makes the green option look worse than it is once lifetime costs are tallied.
What this doesn't capture
Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.
Related calculations worth running
Plans get firmer when you triangulate. Alongside this one, the compound interest calculator, the high yield savings calculator, and the sustainable building roi calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.
