Definition
The Money-Weighted Rate of Return (MWRR) is a measure of an investment’s performance that accounts for the size and timing of cash inflows and outflows. It determines the rate of return needed to equate the present value (PV) of all cash flows to the initial investment amount. In simpler terms: it’s like measuring your investment performance while wearing a backpack full of cash—heavy deposits make you work harder for returns!
| Attribute | Money-Weighted Rate of Return (MWRR) | Time-Weighted Rate of Return (TWRR) |
|---|---|---|
| Definition | Accounts for cash inflows/outflows | Ignores cash flows |
| Calculation | Finds IRR considering cash timing | Gets the return per period only |
| Usage | Good for personal portfolios | Best for fund performance comparisons |
| Implication | Individual investor perspective | General market performance |
How To Calculate MWRR
To calculate the MWRR, you’ll find the internal rate of return (IRR) that sets the present value of all cash flows equal to the initial investment. The formula looks fancy, but it’s basically setting your money’s future worth equal to what you put in.
Here’s the formula: $$ PV = CF_0 + \frac{CF_1}{(1 + r)^1} + \frac{CF_2}{(1 + r)^2} + … + \frac{CF_n}{(1 + r)^n} $$
Where:
- \(PV\) = Present Value of all future cash flows
- \(CF\) = Cash Flows at time \(t\)
- \(r\) = MWRR you are trying to find
Example of MWRR
Imagine you invested $10,000 and added $2,000 in year two while withdrawing $1,500 in year three. By year four, your investment is worth $14,000. To find your MWRR, you’d plug those numbers into the formula above and play the waiting game (or use Excel).
Related Terms
- Internal Rate of Return (IRR): A crucial cousin to MWRR, representing the discount rate that makes the net present value of all cash flows from an investment equal to zero.
- Time-Weighted Rate of Return (TWR): Measures compound growth over time with no regard to the timing of cash flows—ideal for comparing the performance of fund managers.
Fun Fact
Did you know? The term “money-weighted” has nothing to do with lifting weights. It’s about cash flows rather than dumbbells!

Frequently Asked Questions
-
What’s the difference between MWRR and IRR?
- MWRR is essentially IRR, with the twist that it considers when money went in and came out, instead of just focusing on returns over time.
-
Why should I care about MWRR?
- It helps you understand how much your investment is really making, taking to heart your unique cash flow situation, which can be more important than the cold hard number!
-
Can MWRR be negative?
- Yes! Just like a bad haircut, your investment can yield more bad surprises than good ones.
-
Is MWRR useful for all investors?
- Absolutely! Especially for those who actively manage their portfolio with deposits and withdrawals.
-
Where can I find MWRR calculators?
- Various finance apps and investment websites have features to calculate MWRR for you—just scour the internet like a treasure map!
