ESG Portfolio Return Calculator

ESG vs conventional returns.

Compare ESG portfolio return vs conventional including the fee premium across years — see whether the ethics premium costs you final wealth.

What this tool does

This tool models how a portfolio's value might grow over a set period under two different investment approaches: one focusing on environmental, social, and governance criteria, and one following conventional investment practices. It calculates the future value of each approach by applying their respective annual returns, then accounts for the additional fees typically associated with ESG-screened investments. The result shows the difference in portfolio value between the two strategies after your chosen timeframe. The calculation is most sensitive to the return percentages you input and the length of the investment period. For example, someone comparing a 5-year investment scenario across both approaches would see how fee premiums affect long-term outcomes. Note that this illustration assumes consistent annual returns and does not account for market volatility, tax implications, or changes in fees over time.

ESG (Environmental, Social, Governance) portfolios often charge 0.1-0.3% premium over conventional index funds. Long-term return data mixed: some studies show ESG matches or slightly outperforms; others show modest underperformance. This tool compares ESG vs conventional projection over time.

100k portfolio, ESG return 7%, conventional 7.5%, ESG fee premium 0.2%, 10 years. ESG net return: 6.8% × 10y = future value 193k. Conventional: 7.5% × 10y = 206k. ESG underperforms by 13k (6.3%). Modest cost for value alignment if that matters to investor.

ESG performance debate: 2018-2021 ESG outperformed (tech-heavy ESG indexes captured Big Tech gains). 2022-2023 ESG underperformed (excluded oil/defense which boomed). Long-term: ESG and conventional roughly equivalent. Pick ESG for value alignment, not solely return optimization. Costs matter most: low-fee ESG (0.10-0.20%) competitive; expensive active ESG (0.50%+) drags returns.

A worked example

Try the defaults: portfolio value of 100,000, esg return of 7%, conventional return of 7.5%, esg fee premium of 0.2%. The tool returns -13,034.17. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Portfolio Value, ESG Return %, Conventional Return %, ESG Fee Premium %, and Years. 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.

The formula behind this

ESG net return = ESG % - fee premium. ESG FV = portfolio × (1 + net)^years. Conventional FV similarly. Difference = ESG FV - conventional FV. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Why investors run this

Most people's intuition for compounding is wrong — not because the math is hard, but because linear thinking doesn't account for curves. Running numbers through a calculator like this one is the cheapest way to recalibrate that intuition before making an irreversible decision about contribution rate, asset mix, or retirement age.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. The number represents one scenario rather than a forecast.

Example Scenario

££100,000 ESG (7% - 0.2%) vs conv 7.5% × 10y = -13,034.17.

Inputs

Portfolio Value:£100,000
ESG Return %:7
Conventional Return %:7.5
ESG Fee Premium %:0.2
Years:10
Expected Result-13,034.17

Sources & Methodology

Methodology

This calculator computes the difference between projected future values of an ESG portfolio and a conventional portfolio. It applies the ESG return percentage and conventional return percentage to your starting portfolio value, each net of their respective fees. The ESG net return is calculated by subtracting the ESG fee premium from the stated ESG return. Both portfolios are then grown using compound interest over your specified time horizon, with future value calculated as initial amount multiplied by (1 + net annual return) raised to the number of years. The result shows the absolute difference between these two projected values. The calculator assumes constant annual returns, annual compounding, no additional contributions or withdrawals, and does not model fees other than the ESG premium, market volatility, tax effects, or inflation.

Frequently Asked Questions

Does ESG underperform?
Mixed evidence. 2010-2020 studies show roughly equivalent performance. 2018-2021 ESG outperformed (tech-heavy). 2022 ESG underperformed (energy excluded during oil price spike). Long-run: roughly equivalent +/- 0.5% per annum. Fee premium can be the main driver of difference.
What does ESG include?
Environmental: carbon, water, waste, biodiversity. Social: labor practices, community, diversity, human rights. Governance: board independence, executive pay, anti-corruption. ESG ratings vary by provider (MSCI, Sustainalytics, S&P) - same company can score differently across raters.
ESG categories?
Negative screening: exclude tobacco, weapons, fossil fuels. top-tier: own best ESG performers per industry. Thematic: climate solutions, renewable energy. Impact investing: measurable social/environmental impact. Different approaches give different return profiles.
to choose ESG?
Choose for: value alignment, future-proofing portfolio against regulatory shifts, supporting positive companies. Don't choose only for: outperformance (unproven), social signaling (low-substance ESG funds exist - 'greenwashing'). Verify holdings match your values - some ESG funds hold companies you might disagree with.
