About this calculator
Payments can be at the end of each period, as in most loans and payouts, or at the start, as with rent.
How to use it
- Choose what you want to find.
- Enter the lump sum or the payment.
- Enter the rate, years, frequency and timing.
The formula
- PV
- the lump sum
- PMT
- each payment
- i
- rate per period
- n
- number of payments
Worked example
₹10 lakh paid out monthly over 10 years at 7%
- Monthly payment (end of month): ₹11,611.
- You receive ₹13,93,302 in all; ₹3,93,302 is interest on the balance.
- Conversely, ₹10,000 a month for 10 years at 7% is worth ₹8,61,264 today.
What the result means
Use the payment mode to see what income a corpus can give for a fixed period, and the value mode to compare a lump sum with a series of payments.
Assumptions
- A fixed rate and equal payments.
Limitations
- Insurance-company annuities pay for life and use their own rates; ask for a quote.
Frequently asked questions
Is this the same as a pension annuity?
It shows a fixed-term payout. Life annuities from insurers pay for life at quoted rates.
Start or end of period?
End for most payouts and loans; start for rent and some investments.
How is this different from SWP?
An SWP withdraws a fixed amount and leaves what remains; this works out the payment that uses up the sum exactly.
