3 example scenarios

See how your starting capital, savings and investment growth build the ending value.

$100,000 starting capital + $1,000 monthly; 6% assumed total return, 2.5% inflation, 0.25% additional annual costs; 20 years.

1. Build your plan

What would you like to calculate?

Inflation & additional assumptions · 2.5% inflation · 0% costs

2. Understand your projection

Enter starting capital of 0 or more.

Goal model assumptions

Returns compound monthly at the monthly equivalent of the assumed annual total return. Additional costs are deducted proportionally before month-end contributions. Contribution increases occur annually. Inflation compounds monthly for purchasing-power comparisons. Required contributions use the same model and round the selected payment frequency up to cents. This is an illustrative projection with a smooth return path; taxes and market volatility are excluded.
