Contribution growth at a rate you choose.
Open the Compound Growth tool →Future value = your starting balance grown at the rate you choose, plus each contribution grown for the periods it has left to compound. We compound every period exactly (no rounding drift).
The rate of return is your assumption, clearly labeled, never a prediction. We don't guess markets; change the rate to see optimistic and conservative cases.
