Real return measures what remains from performance after annual fees and inflation. It answers a different question from nominal return: does capital truly grow in purchasing power? The page therefore projects both a future balance in current currency units and its equivalent value in today's money.
Real return = ((1 + nominal return - annual fees) / (1 + inflation)) - 1
The real rate used is: ((1 + nominal return net of fees) ÷ (1 + inflation)) − 1. The engine also applies the net return by period, adds contributions according to the selected frequency, then divides nominal value by the cumulative inflation factor to obtain purchasing power.
Example matching the default values: €100,000 starting capital, €500 per month, 6% nominal return, 2.5% inflation, 0.5% annual fees and 20 years. The annual real return is about 2.93%. The final projection reaches about €506,209 nominal, or around €308,924 in today's purchasing power, with €220,000 invested.
Nominal value shows the future displayed balance. Real value shows what that balance represents after monetary erosion. If the gap becomes wide, the plan depends heavily on net return staying above inflation.
Nominal return is the visible rate before inflation adjustment. It can look comfortable while being insufficient if prices rise almost as much.
Fees are subtracted from return before the real calculation. A small-looking fee difference can matter greatly over twenty years.
Inflation reduces future purchasing power. The engine compounds it period by period to compare the ending balance with an equivalent current value.
Regular deposits increase both invested capital and future value. They must be separated from real gain because part of the final balance simply comes from saving effort.
Real value answers the practical question: what will this amount represent in spendable terms if prices follow the entered assumption?
Future value displays a nominal projection. Real return removes the effect of fees and prices to judge purchasing-power progress.
For a financial decision, do not keep only the payment, return or final amount. Check total cost, fees, duration, possible inflation and available cash flow to understand what the result really implies. This extra context makes the estimate easier to compare with a quote, statement or long-term plan.
Increase the rate, lower the expected return or add fees to see how resilient the result is. If a small change removes the safety margin, treat the number as a fragile assumption rather than a secured target. Keep the cautious case visible before committing money.
An online finance calculation helps prepare comparisons, but it does not replace a bank offer, statement, tax document or contract. Before acting, reconcile the result with official documents and rules that apply to your situation.
Keep the entered values, date, currency, rate, term and fees included or excluded. This record makes the simulation repeatable and explains why two similar outputs can lead to different decisions.
€100,000 capital, €500/month contribution, 6% return, 2.5% inflation, 0.5% fees, 20-year term.
| Year | Nominal value | Real value | Amount invested |
|---|---|---|---|
| 1 | €111,650 | €108,927 | €106,000 |
| 5 | €165,019 | €145,852 | €130,000 |
| 10 | €249,995 | €195,296 | €160,000 |
| 20 | €506,209 | €308,924 | €220,000 |
A lasting price increase quickly reduces real value.
Heavier annual fees lower net return before the adjustment.
They support ending value but should not be confused with performance.
Testing a lower rate reveals the plan's safety margin.
This estimate is general information, not personalized financial advice. It assumes constant rates, regular contributions and does not model tax, volatility, losses, caps, fee changes or changing inflation.
((1 + net return) ÷ (1 + inflation)) − 1, with rates expressed as decimals in the reasoning.
Because fees first reduce the return actually earned by the saver.
No. It depends entirely on return, fees, inflation and contribution assumptions.
Nominal return shows displayed growth; real return shows purchasing-power growth.
Calculate the impact of inflation on money: future cost, remaining purchasing power, real loss and scenarios over 5, 10, 20 or 30 years.
Measure the real impact of fees on investment growth: entry fees, management fees, exit fees, inflation, net return and final value after costs.
Analyze the total profitability and yield of capital investments.
Project your future wealth through disciplined contribution and time.
Calculate future value from capital, rate, duration and compounding frequency, with interest earned and growth scenarios.
Simulate recurring investments: total invested, accumulated units, average cost, projected value, potential gain, fees, inflation and return scenarios.
