Equity historically returns more than debt but with higher volatility. 50,000 over 20 years: at 8% equity return = 233,000; at 4% debt return = 110,000 — 123,000 gap. The gap rewards accepting short-term volatility. Young investors usually lean heavily equity; approaching retirement, the balance shifts toward debt for stability.
Asset class comparison.
Quick example
With investment amount of 50,000 and horizon of 20 (plus expected equity return of 8% and expected debt return of 4%), the result is 123,491.70. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Investment Amount, Horizon, Expected Equity Return, and Expected Debt Return. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
What's happening under the hood
Standard compound growth for each asset class. Annual compounding. Ignores volatility drag which favours lower-volatility debt in practice. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why investors run this
Most people's intuition for compounding is wrong — not because the math is hard, but because linear thinking doesn't account for curves. Running numbers through a calculator like this one is the cheapest way to recalibrate that intuition before making an irreversible decision about contribution rate, asset mix, or retirement age.
What this doesn't capture
Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
Equity vs debt produces future values based on the inputs provided.
