See how your annuity premiums grow during the accumulation phase — and exactly how fees, surrender charges, and the type of contract you choose affect what you'll actually walk away with.
This calculator models the accumulation phase of a deferred annuity — the years between your initial premium and the point where payments begin. That distinction matters: for modeling income payments or lifetime withdrawal strategies, use the separate Annuity Payout Calculator. Here, inputs are your premium amount (lump-sum or annual contribution), contract start date, growth rate scenario (conservative/moderate/aggressive or a manual override), annual expense ratio (mortality and expense charges, administrative fees, rider fees), and surrender charge schedule if you might need early access. The output shows accumulation value at each year, the total cost of fees over the holding period, and the net surrender value after early-withdrawal charges.
1. Enter your initial premium or annual contribution amount and whether payments are lump-sum or recurring.
2. Select your annuity type (fixed, variable, fixed indexed) or enter a manual assumed annual growth rate.
3. Enter the annual expense ratio — commonly 1.0%–1.5% for variable contracts; near 0% for fixed-rate contracts.
4. Enter the surrender charge schedule (e.g., 7% declining over 7 years) if applicable.
5. Set your accumulation horizon in years — typically how long until you plan to annuitize or begin withdrawals.
6. Click Calculate to see year-by-year contract value, cumulative fees paid, and net surrender value.
The calculator applies compound growth adjusted for annual fees:
Accumulation Value (Year N) = Premium × (1 + r − fee)^N
For recurring contributions, it uses a future value of annuity series formula. The surrender value = Accumulation Value × (1 − applicable surrender charge percentage). Tax deferral is reflected by not deducting annual taxes on growth — in a taxable account, that same growth would erode each year. The fee drag visualization compares the tax-deferred annuity balance against a hypothetical taxable account earning the same gross return, typically making the annuity's advantage most visible over horizons of 10+ years for investors in the 22%+ bracket.
The most instructive output isn't the headline accumulation value — it's the cumulative fees line. Even a 1.25% annual expense ratio on a $200,000 contract costs roughly $43,000 in compounded fee drag over 20 years at a 6% gross return. That's money that never compounds for you. The calculator makes this concrete so you can decide whether the guarantee or insurance element of the contract justifies that cost relative to a low-cost index fund in a taxable account.
The annuity type you choose determines the growth assumption that drives your accumulation calculation.
Fixed annuities credit a declared rate set by the insurer for a specified term — current multi-year guaranteed annuity (MYGA) rates in 2026 range from roughly 4.5% to 5.2% for 5-year contracts, competitive with CDs but with tax-deferral advantages. The accumulation math is exact and deterministic once you know the rate.
Variable annuities invest your premium in subaccounts (essentially mutual funds). Growth is market-linked — historical subaccount returns have averaged closer to 6–8% gross before the 1%–1.5% annual M&E charges that characterize most variable contracts. The calculator lets you run pessimistic (4%), base (6.5%), and optimistic (9%) scenarios to bound the outcome.
Fixed indexed annuities (FIAs) credit interest linked to an index like the S&P 500, subject to a cap rate (e.g., 10–12%) or participation rate (e.g., 60–80%). The floor is typically 0% — you don't lose principal if the index drops, but you don't capture the full upside either. Long-run FIA returns historically land around 4–6% net of caps.
Surrender charges are the feature that locks annuity buyers into contracts. A typical schedule might start at 7% of contract value in year 1 and decline by 1% per year, reaching 0% in year 8. The practical implication: if you need the money before the surrender period ends, you pay a significant early exit cost.
The calculator's surrender value line makes this concrete. A $250,000 contract in year 3 of a 7-year schedule with 5% remaining charges and $295,000 accumulated value yields a surrender value of $295,000 × (1 − 0.05) = $280,250 — not the headline accumulation figure. Additionally, any earnings withdrawn before age 59½ face a 10% IRS penalty plus ordinary income tax.
Before purchasing, model at least three "what if I need this money in year 4" scenarios. Annuities make the most sense for premium dollars you genuinely won't need during the surrender period.
The gap between gross and net return in a variable annuity is wider than most buyers realize at purchase:
A $200,000 contract with 2.5% total annual fees earning 7% gross actually grows at 4.5% net — accumulating to $535,000 after 20 years instead of $772,000 at 7% gross. That $237,000 difference is the cumulative cost of fees. The calculator's fee-drag table visualizes this gap year by year.
The largest driver of accumulation is time — annuities are long-duration instruments, and their tax-deferral advantage over taxable accounts grows nonlinearly with time horizon. Initial premium size determines the base on which compounding works. The assumed growth rate (or insurer-declared rate for fixed) sets the gross return ceiling. Annual fees are the biggest controllable variable — lower fees compound significantly over decades. Surrender charge period determines liquidity risk: money needed before year 8 may cost 2–5% in exit charges. Tax bracket affects how valuable the tax deferral is — the benefit is greater in the 24%+ brackets than in the 12% bracket. Finally, age at purchase interacts with 59½ — buying too young adds years of potential penalty exposure on any early withdrawals.
Carlos locks in 4.8% with zero annual fees (fixed contract). After 5 years: $150,000 × (1.048)^5 = $189,620. No M&E drag. At maturity he can roll to another MYGA, annuitize, or withdraw. His tax bracket is 24%, so the deferral saves him from paying taxes on the ~$6,900 in annual interest that would have been taxable in a CD or bond ladder.
At a 7% gross subaccount return and 2.2% in fees, Diane's net growth rate is 4.8%. Accumulation at 20 years: $300,000 × (1.048)^20 = $769,000. The same $300,000 growing at 7% gross would reach $1,160,000 — the $391,000 gap is the 20-year cost of the 2.2% fee load. The calculator flags this gap and suggests she compare a low-cost index portfolio with periodic tax-loss harvesting as an alternative.
1. Compare MYGAs to CDs before buying a fixed annuity — current MYGA rates often beat CD rates with the added benefit of tax deferral, but MYGA principal isn't FDIC-insured.
2. Check the surrender charge schedule against your liquidity timeline. Never put money in an annuity that you might need before the surrender period ends.
3. Request the full fee disclosure (prospectus or product summary) before signing. Total annual fees above 2% significantly erode the tax-deferral advantage.
4. Model both fixed and variable scenarios in the calculator — if the fixed option's guaranteed rate nearly matches the after-fee variable projection, the certainty of fixed may be preferable.
5. Evaluate riders separately. An income rider for $0.75%/year sounds cheap but competes with other fee-efficient income strategies. The calculator lets you add and remove riders to see the net impact.
6. Consider annuities for money above IRA/401(k) maximums. Their biggest edge is tax deferral — which only matters if you've already filled tax-advantaged accounts.
A: A deferred annuity is an insurance contract where you pay premiums now, the money grows tax-deferred during the accumulation phase, and you receive income payments at a future date — either as a lump sum, periodic withdrawals, or annuitized payments.
A: Earnings inside an annuity are not taxed each year. Instead, taxes on gains are deferred until withdrawal, allowing the full gross return (before income tax) to compound. Upon withdrawal, earnings are taxed as ordinary income.
A: Multi-year guaranteed annuity (MYGA) rates for 5-year contracts are running approximately 4.5%–5.2% in 2026, depending on the insurer and your state.
A: Variable annuities typically charge M&E fees (0.60%–1.40%), administrative fees, subaccount expense ratios, and optional rider fees. Total annual costs commonly range from 1.0% to 3.5%. Fixed annuities generally have no explicit annual fee — the insurer's margin is embedded in the declared rate.
A: Unlike IRAs or 401(k)s, non-qualified annuities have no IRS contribution limit. However, most insurers set per-contract maximums, often $1–$2 million.
A: Accumulation value is the contract's total grown value. Surrender value is what you actually receive if you cancel — accumulation value minus any applicable surrender charges.
A: Annuities can be effective tax-deferral and income-planning tools for specific situations — typically for investors who've maxed other tax-advantaged accounts, are in a 24%+ bracket, and want guaranteed income or principal protection. They're generally not cost-effective as a first savings vehicle.
A: Most contracts include a death benefit equal to at least the greater of accumulated value or total premiums paid. Enhanced death benefit riders can lock in higher values. The beneficiary receives the proceeds, which are subject to ordinary income tax on gains.
