Investment Target Time
Solve the time to grow by a chosen multiple at a constant rate.
Your numbers
Time to target
Educational estimate using your entered assumptions; no live prices, tax rules or guaranteed returns.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use t = ln(M)/ln(1+r). M is the target growth multiple, r is the annual effective growth fraction, and t is years. This generalizes doubling to the multiple you enter.
Solve the time to grow by a chosen multiple at a constant rate.

Scope and limitations
Educational estimate using your entered assumptions; no live prices, tax rules or guaranteed returns.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
