How to use this tool

Target-Based Investing

Working backwards is one of the most effective ways to plan investments. Setting a fixed target amount (for a house downpayment, college fund, or travel) tells you exactly what monthly budget you must commit to.

Define your future target budget to reveal your required savings rate.

Mathematical Foundation

The Goal Planning Formula

The required monthly savings (PMT) is calculated using the sinking fund formula:

Required Monthly Savings = Target × [i / ((1 + i)n - 1)] × [1 / (1 + i)]

Target: Target Financial Goal
i: Monthly Interest Rate (Annual Rate / 12 / 100)
n: Total Months (Horizon × 12)

Common Inquiries

Frequently Asked Questions

Planning details for target funds.

Should I adjust my target for inflation?

Yes. If your goal is 10 years away (e.g., child’s education), the actual cost in 10 years will be higher due to inflation. You should input the future inflated cost rather than today’s current cost.

Is it better to invest as a lump sum or monthly?

If you have the capital available today, investing as a lump sum allows the entire amount to compound for the full duration. Otherwise, setting up a consistent monthly plan reduces market volatility risks.
