DCA ending balance: $69,762.45
Better strategy: Lump sum

Lump Sum vs DCA Logic

Lump sum invests the full amount immediately, while DCA invests fixed monthly slices until the cash runs out.

The shared Lump Sum vs DCA Calculator compares one immediate investment path against a staggered monthly-investing path using the same return assumption and time horizon.

Invest $30,000 immediately for the lump-sum path.
Invest up to $5,000 each month for the DCA path until the full amount is deployed.
Compound both paths using the same 9% annual return assumption.
Compare the ending balances after 10 years to find the difference.

How to read this comparison

This page holds the total cash amount and return assumption constant while changing only the timing of when the money is invested.

It does not claim one strategy is always better. It shows what this specific return path implies under a smooth, simplified market assumption.

Why lump sum often leads in a rising market assumption

If returns are assumed to be positive and steady, the lump-sum path gives more money more time in the market. That usually creates a mathematical advantage.

DCA can still be appealing for behavioral reasons, cash-flow constraints, or uncertainty about near-term market timing. This calculator only compares the projected balances.

What this page leaves out

The model does not include taxes, fees, irregular returns, or cash yield on uninvested money. Real markets do not deliver the same return every month.

Use the full Lump Sum vs DCA Calculator to test your own amount, monthly cadence, and time horizon, then pair it with your risk tolerance and real cash-availability constraints.

Frequently Asked Questions

Which strategy wins in this example?

Under these assumptions, the result is lump sum by about $1,258.46.

Why does lump sum often come out ahead in these pages?

With a smooth positive return assumption, investing earlier gives the money more time to compound. That mathematical edge often favors lump sum.

Does DCA reduce risk in this model?

Not directly. The calculator uses a constant return assumption, so it does not model market volatility or sequence risk. DCA can still matter behaviorally in real life.

Is the DCA amount always fully invested by the deadline?

The model invests up to the stated monthly amount until the total cash amount is fully deployed. Any remaining cash stays uninvested once the period ends.

Should I choose based only on this result?

No. Consider market uncertainty, personal behavior, taxes, fees, and whether the cash is truly available to invest now.
