Compounding calculator, with a reality check

See how a balance grows when each month's result is added to the next, with monthly deposits or withdrawals, and how big a steady monthly % really is in a year.

How compounding works

Each month earns its % on the balance it started with, so the gains themselves start earning. Over many months the curve bends upwards. Example: $1,000 at 2 % a month with $100 added each month is about $4,650 after 24 months.

The reality check

A steady monthly % is the hardest part. 10 % a month sounds small but is about 214 % a year; 20 % a month would be about 790 %. Real trading has losing months and drawdowns, and one large loss can undo many good months: a 50 % loss needs a 100 % gain to get back. Use the calculator to set calm goals, not as a forecast, and keep the risk per trade small (see the lot size calculator).

Withdrawals

Enter a minus amount to take money out each month. The table shows how withdrawals slow the growth, and the balance never goes below zero.

Questions

What is a realistic monthly return?

There is no safe number. Results change from month to month and many months lose. Treat any steady % as a goal, not a promise.

Is the monthly add counted before or after the gain?

After: each month first earns its % on the starting balance, then the deposit or withdrawal is added.

Does it include fees and taxes?

No. Spreads, commissions, swaps, platform fees and taxes all lower the real result.
