See the regular income a lump sum can pay out over a set number of years at a given rate — plus the total paid and interest earned along the way.
A simplified fixed-payout (amortized) model — it assumes a constant rate and depletes the balance to zero over the term. Real annuities have fees, riders, and different structures. General information, not financial or annuity advice.
This treats the payout like a loan in reverse: the balance earns a return while it's paid down to zero over the term. Higher rates or shorter terms mean bigger payments; longer terms stretch the same pot thinner.
Payment = balance × r ÷ (1 − (1 + r)⁻ⁿ)
No — it's the math of a fixed-term payout. Insurance annuities add fees, guarantees, and options that change the number. Use this to sanity-check, not to buy.
Then you'd only spend the interest, not the principal — a much smaller payment. This model spends the whole balance over the term you set.
