Enter your target amount, timeline, and expected return rate. We’ll calculate exactly how much you need to save every month — with compound growth factored in.
Let’s figure out how much to save each month — step by step.
Serrari provides educational tools — we are not financial advisors. Results are estimates based on the inputs you provide.
The calculator uses the future value of an annuity formula, rearranged to solve for the monthly payment. It takes your target amount, subtracts the future value of any existing savings (which also grow through compounding), and calculates the fixed monthly contribution needed to cover the gap.
The annual return rate is divided by 12 to get the monthly rate, and compounding happens monthly. This means your returns earn returns every month — the compound interest effect that makes saving consistently so powerful. Even a 1% difference in annual return can change your monthly savings amount by thousands of shillings.
Where to park your monthly savings for the best growth toward your goal.
| Product | Expected Return | Best For | Minimum |
|---|---|---|---|
| Money Market Funds | 8 – 12% | Short-term goals (under 2 years) | KES 100 |
| Unit Trusts (Balanced) | 10 – 15% | Medium-term goals (2–5 years) | KES 1,000 |
| Treasury Bills | 14 – 17% | Fixed timeline, capital preservation | KES 100,000 |
| Treasury Bonds | 12 – 14% | Long-term goals (5+ years) | KES 50,000 |
| Fixed Deposits | 6 – 10% | Guaranteed returns, low risk | KES 10,000+ |
| SACCO Savings | 8 – 14% | Regular contributions + dividends | Monthly contribution |

Assuming 10% annual return, compounded monthly. Lower amounts mean longer timelines or higher rates.
