Life contingencies, insurer fees, surrender charges and tax are not modelled; this is the value of the payment stream itself.
This values a payment stream under the assumptions you enter. It is not a quote: a real annuity contract prices mortality, insurer fees, surrender charges, guarantees and tax, and a structured-settlement transfer needs court approval. Take the figures to a qualified adviser before acting on them.

For a graduated stream this is the first payment; later ones grow by the escalation rate.
The premium paid, settlement offered or account value. Used when solving for the payment, the term or the rate.
Nominal annual rate, compounded at the payment frequency.
Not used when you are solving for the number of periods.
Zero for a level annuity; 5 for a Powerball or Mega Millions jackpot annuity; a cost-of-living figure for an escalating settlement.

How this is worked out

5 steps
  1. Rate per period = 5% / 12 = 0.41666667%
  2. Level ordinary annuity of 1649.89 for 240 periods
  3. Present value = 250000
  4. Value at the end of the term = 678160.07
  5. Total of all payments = 395973.44

The standard compound-interest results; equal to the spreadsheet PV, FV, PMT, NPER and RATE functions with type = 0 or 1.
Growing-annuity identity PV = PMT/(i-g) x [1 - ((1+g)/(1+i))^n], and n x PMT/(1+i) when i = g
Derived by summing the geometric series of discounted payments PMT(1+g)^(k-1)/(1+i)^k for k = 1..n.
Powerball - Prize Chart (annuity option)
The jackpot annuity is 30 graduated payments over 29 years, each 5% larger than the one before, with the first paid immediately - a 30-period growing annuity due at g = 5%.

The method follows Annuity identities PV = PMT[1-(1+i)^-n]/i and FV = PMT[(1+i)^n-1]/i, with the annuity-due factor (1+i), Growing-annuity identity PV = PMT/(i-g) x [1 - ((1+g)/(1+i))^n], and n x PMT/(1+i) when i = g and Powerball - Prize Chart (annuity option).

What you can compare

Change one input at a time to see how it affects Present value, Future value and Payment each period. The inputs you can vary are Payment each period, Lump sum today, Interest or discount rate, Length of the payment stream, Payment frequency and Payments are made.
