Scenario A

Base assumptions

Scenario A is your base case. Enter the starting portfolio, contribution, time horizon, return and fee assumptions you want to model.

Base case inputs

These inputs define Scenario A. Scenario B can then be matched to this base case or adjusted to test an alternative.

Total annual fee assumption

ETF TER + platform fee = 0.57%

Scenario B

Alternative assumptions

Scenario B is your alternative case. It uses the same starting portfolio, currency and time horizon as Scenario A, so the comparison isolates changes in contribution, return and fees.

Quick tests

Start with a common alternative assumption, then adjust the inputs below if needed.

Contribute more: +25% monthly contribution. Lower fees: 50% lower platform fee. Lower return: -2% annual return. Higher return: +2% annual return.

Scenario B total annual fee assumption

ETF TER + platform fee = 0.42%

Projected outcome

Your projected outcome

Based on the assumptions entered, this is the estimated portfolio value after contributions, compounding and annual fee drag.

Projected portfolio value

$321,549

Over 15 years, this scenario projects a final net value of $321,549, based on $190,000 in total contributions and an assumed 7.00% annual return before fees.

Total contributions

$190,000

Starting value plus all monthly contributions over the full period.

Estimated investment growth

$131,549

Projected net growth after contributions and estimated fee drag.

Estimated fee drag

$17,146

Equivalent to approximately 5.1% of the gross projected value.

Gross value before fees

$338,695

Estimated portfolio value before ETF and platform fees are deducted.

Inflation lens

Future value in today's money

This converts the projected final value into an estimated purchasing-power equivalent using your inflation assumption.

Nominal projected value

$338,695

Inflation-adjusted value

$233,857

Assumed inflation rate: 2.50%. This is illustrative only and does not model country-specific cost of living, tax, FX movement or personal spending patterns.

Scenario comparison

Compare two sets of assumptions

Scenario A uses your main inputs. Scenario B lets you test a different contribution, return or fee assumption without treating the result as a recommendation.
