Inputs
Use realistic assumptions. Small changes can shift cash values materially.
Example data table
Sample scenarios (illustrative) to sanity-check your inputs.
| Scenario | Age | Profile | Face | Policy | Assumed rate | Estimated annual premium |
|---|---|---|---|---|---|---|
| Conservative starter | 30 | Female, non-smoker, Preferred | $250,000 | Universal Life | 4.0% | $2,900 – $3,600 |
| Balanced lifelong | 40 | Male, non-smoker, Standard | $500,000 | Whole Life | 4.5% | $8,500 – $10,500 |
| Higher-risk profile | 55 | Male, smoker, Substandard | $250,000 | Indexed UL | 5.0% | $10,800 – $14,500 |
Ranges are broad because carrier pricing varies by underwriting and product design.
Formula used
This calculator uses a transparent, simplified structure to turn inputs into an estimate.
Premium estimate
Annual base premium is built from a rate per $1,000 of face amount.
annual_base_premium = (face ÷ 1000) × base_rate_per_1000
annual_premium = (annual_base_premium + riders + fees) × mode_factor
Cash value projection
Each year adds net allocation, then grows at an assumed or guaranteed rate.
net_allocation = annual_premium − load − fees − COI (floored at 0)
cash_value_t = (cash_value_{t−1} + net_allocation) × (1 + rate)
How to use this calculator
- Enter your age, risk profile, and a face amount that matches your goal.
- Choose a policy type and payment style to reflect your design preference.
- Set an assumed rate and a guaranteed rate to see two projections.
- Add fees, premium load, and optional riders if you want fuller cost estimates.

Premium drivers you can stress-test
This model prices premium per $1,000 of face using age bands, then applies risk multipliers. For many profiles, the base rate ranges about $4 to $25 per $1,000 annually, before riders and fees. For example, $250,000 at $7 per $1,000 implies about $1,750 base premium each year before extras. Monthly billing uses a mode factor near 1.08, so a $9,000 annual premium becomes roughly $750 per month. Short-pay designs raise premiums to fund earlier.
Net allocation after loads, fees, and COI
Each year the calculator subtracts your premium load, policy fees, and a simplified cost of insurance (COI). COI is estimated per $1,000 of face and increases with attained age; conservative stance adds about 25% while aggressive reduces about 15%. Net allocation is floored at zero, highlighting when charges consume premium and weaken accumulation.
Cash value growth under assumed and guaranteed rates
After net allocation is credited, cash value compounds at either the assumed crediting/dividend rate or the guaranteed rate. A 4.5% assumed rate grows $5,000 of net allocation to about $75,000 over 10 years, while 2.0% produces about $55,000, before charges. Whole life uses the dividend scale; UL-style products use the crediting rate.
Break-even timing and surrender value impact
Break-even is the first year assumed cash value meets cumulative premiums. It often lands between years 8 and 15 when loads are modest and COI is average. Surrender value is reduced by a declining charge for years 1-10, starting near 12% and trending to 0%, so early access can be lower than stated cash value even when performance is steady.
Riders, inflation option, and death benefit choice
Optional riders add protection but raise annual cost. Accidental death benefit is approximated near $0.50 per $1,000, critical illness near $1.20 per $1,000, and waiver adds about 3% of base premium. Inflation can increase face up to 6% yearly, which also lifts COI. Increasing death benefit uses face plus assumed cash value, supporting higher protection at higher cost.
FAQs
What does the assumed rate represent?
It’s the annual growth rate applied to net allocations after charges. For whole life it reflects a dividend scale; for UL-style products it reflects credited interest. It is not a promise and can change with markets and carrier performance.
Why can net allocation become zero?
If premium load, fees, and cost of insurance are high relative to your premium, there may be little left to credit to cash value. This can happen at older ages, high inflation increases, or conservative COI assumptions.
Is the break-even year guaranteed?
No. Break-even depends on assumptions and on policy expenses over time. The calculator reports when assumed cash value reaches cumulative premiums, but surrender charges, loans, and real crediting can shift the timing significantly.
How do I choose level versus increasing death benefit?
Level keeps death benefit near the face amount, usually improving cash value efficiency. Increasing adds cash value to the face amount, raising protection but typically increasing charges. Choose based on whether you prioritize accumulation or maximum lifetime coverage.
How do riders change results?
Riders add annual cost and may change the protection profile. In this model, waiver adds a percentage of base premium, while ADB and critical illness are priced per $1,000 of rider amount. Higher rider cost reduces net allocation and projected cash value.
Why will carrier illustrations look different?
Real illustrations use product-specific charges, expense loads, underwriting classes, and regulatory assumptions. They also model lapse-supported pricing and bonus features. Use this tool to compare scenarios, then confirm with an official illustration from the insurer.
Important notes
- Real carrier premiums vary by underwriting, state/jurisdiction, product, and riders.
- Cash value is sensitive to loads, COI, crediting, and persistency assumptions.
- Use this as a planning tool, then validate with an official illustration.
