- How often should I update my net worth?
- Once or twice a year is enough for most families — say every 31 March and 30 September. Use the same date each time so the comparison is fair, value assets conservatively, and watch the direction of the number rather than the number itself.
- How is PPF interest calculated?
- PPF interest is calculated on the lowest balance between the 5th and the last day of each month, and credited once a year on 31 March. Investing before the 5th of the month — or the full ₹1.5 lakh before 5 April — earns the most interest. The rate is reset by the government every quarter.
- What is a good CAGR for an investment in India?
- Over 10+ years, diversified Indian equity funds have historically delivered roughly 11–13% CAGR, debt around 6–7% and gold around 8–9%. Judge a CAGR against the asset class and the period, not in isolation — and use XIRR instead of CAGR when money was invested through SIPs.
- Is it better to rent or buy a home in India?
- Buying usually wins when you will stay 10 years or more, the rental yield in your city is above about 3.5%, and the EMI stays under 35–40% of take-home pay. Renting and investing the down payment often wins over shorter horizons and in high-price, low-yield metros.
- How much should I invest each month to reach a goal?
- Use the Multiple-Goal SIP calculator: enter each inflation-adjusted target, timeline and realistic return. It combines the monthly SIPs and compares the total with your investable household surplus.
- How does the Retirement Calculator test lifestyle withdrawals?
- The baseline lifestyle withdrawal setting matches your assumed retirement inflation, and the calculated corpus is designed to fund those inflation-linked expenses through life expectancy. Raise the setting to test higher actual inflation or a better lifestyle and see how much sooner the reserve may be depleted.
- How do I work out my monthly surplus?
- Use the Household Cash Flow Calculator: add take-home and other income, list every monthly expense including EMIs, and the difference is your net free surplus — the amount genuinely available to invest each month. Those same figures feed the Retirement Calculator.
- Are these calculators free to use?
- Yes. Every calculator on PowerMyMoney is free, needs no sign-up, and runs entirely in your browser — no data is stored or shared.
