Example data table
| Age | Sum assured | Term | Paying | Frequency | Expected return | Est. annual premium | Proj. maturity (mid) |
|---|---|---|---|---|---|---|---|

| 25 | 750,000 | 12 | 12 | Annual | 9% | ~63,000 | ~1,520,000 |
Premium drivers you can control
This estimator blends a savings target with a risk proxy. Sum assured, paying term, and charges are the largest levers. A shorter paying term increases annual contribution because the target fund is reached sooner. The expense charge reduces investable premium, so a 0.12 charge means only 88% of the variable portion is invested each year. For stability, the return input is capped at 25%, and the charge input at 40%, preventing unrealistic projections during quick scenario testing.
Frequency effects on cash flow
Payment frequency uses modal factors to reflect administrative loading: annual 1.00, semi-annual 1.02, quarterly 1.035, and monthly 1.06. If the annual estimate is 120,000, monthly mode becomes about 10,600 instead of 10,000. Use frequency to match income timing, but compare total paid over the paying term. Choosing annual payments can reduce total cost but may require budgeting for a single outflow.
Scenario rates and maturity range
The calculator projects three return paths: low is expected minus 2%, mid is expected, and high is expected plus 2%. With an 8% mid assumption, low becomes 6% and high becomes 10%. This range highlights reinvestment risk. A higher return mainly lifts fund value; guaranteed additions and bonuses remain tied to sum assured and term.
Bonuses, additions, and terminal uplift
Reversionary bonus and guaranteed additions accrue yearly as simple proportions of sum assured. For a 1,000,000 sum assured, a 0.02 bonus rate adds 20,000 per year and totals 300,000 over 15 years. A 0.01 additions rate contributes another 150,000. Terminal bonus applies a percentage to total bonuses at maturity, providing a final uplift.
Riders and protection perspective
Optional riders add separate costs. Accidental benefit is priced as a small rate per additional multiple, critical illness uses a higher rate on the selected cover, and waiver of premium adds a load. Review the graph: death benefit is shown as the higher of sum assured plus accruals or 105% of paid premiums, helping you balance protection and long-term accumulation.
FAQs
1) Is this a real quotation from an insurer?
No. It is a planning estimate using simplified assumptions for returns, charges, and risk. Insurers price with underwriting, product rules, and official mortality tables.
2) What does “expected annual return” mean here?
It is the assumed growth rate for the investable portion of premiums. The tool also runs low and high scenarios by subtracting or adding 2% to show a realistic range.
3) How are bonuses and guaranteed additions calculated?
They accrue as simple yearly amounts: sum assured × rate × year. Terminal bonus applies a percentage to total bonuses at maturity. Real plans may credit bonuses differently.
4) Why does payment frequency change my installment?
Modal factors slightly increase the annualized premium for more frequent payments to reflect administrative costs. Annual is treated as the base, while monthly carries the highest factor.
5) What is the surrender value shown in the schedule?
It is an illustrative proxy based on fund value and partial bonus credit after year three. Actual surrender values depend on insurer surrender scales, charges, and paid duration.
6) Can I download my results?
