What this money market fund calculator does

It projects the balance of a money market fund (MMF) from a starting amount plus optional monthly top-ups, compounding the quoted yield daily over the number of years you choose.

MMFs aim to preserve capital while paying a yield that tracks short-term money market rates. The quoted rate changes over time, so the tool lets you model a rate and see the effect of topping up regularly.

How it is calculated

The annual yield is split into a daily rate and applied to the balance each day, so interest itself earns interest — daily compounding. Each monthly top-up joins the balance and compounds from the day it is added.

Quoted MMF yields are usually annualised before fees and tax. Actual returns vary as rates move, and the net figure you receive depends on the fund's fees and any applicable tax, so treat the output as an estimate.

A worked example

Put in ₦100,000, add ₦50,000 a month, and assume a steady yield over 3 years. Your contributions total ₦100,000 + (₦50,000 × 36) = ₦1,900,000, and daily compounding on the running balance adds interest on top — with the earliest naira earning the most because it compounds the longest.

Because MMF rates move with the wider market, it is worth running the projection at a couple of different yields to bracket a realistic range rather than relying on a single rate.

How to read your result

The projected balance assumes the yield holds for the whole period; in practice it will rise and fall. Use a conservative rate for planning and a higher one to see the upside.

Compare the MMF yield against inflation using the inflation calculator. An MMF protects capital and is liquid, but if its yield trails inflation your real return can still be negative.
