What Is a Forecast Bet?

A forecast is a bet where you predict the first and second place finishers in a race. It’s simpler than a tricast but still offers returns significantly higher than a standard win bet.

Two types:

  • Straight Forecast - 1 bet: predict exact order (1st and 2nd)
  • Reverse Forecast - 2 bets: your 2 picks in either order

How the Forecast Calculator Works

  1. Select forecast type - Straight or Reverse
  2. Enter decimal odds for your 1st and 2nd place selections
  3. Enter your stake per bet line
  4. The calculator shows:
    • Number of bets (1 or 2)
    • Total stake
    • Estimated dividend
    • Potential payout and profit

Dividend Calculation

Estimated Dividend = Odds₁ × Odds₂

Note: Actual Computer Straight Forecast (CSF) dividends are calculated by the bookmaker using a complex formula that considers the number of runners, odds of all horses, and pool sizes. Our estimate provides a good approximation.

Straight vs Reverse Forecast

Difficulty Hard Easier
Profit (per unit) Higher Lower (due to 2× stake)

Detailed Examples

Example 1: Straight Forecast

Race: Kempton 2:15, 10 runners

  • 1st place pick: Horse A at 3.00 (2/1)
  • 2nd place pick: Horse B at 5.00 (4/1)

Stake: $2

Metric Value
Dividend 3.00 × 5.00 = 15.00
Payout $2 × 15.00 = $30.00
Profit $28.00

Example 2: Reverse Forecast

Same picks, $2 per line:

Metric Value
Total Stake $4 (2 × $2)
Dividend (if A-B) 15.00
Dividend (if B-A) 15.00
Payout $30.00
Profit $26.00

Example 3: Big-Priced Forecast

  • 1st: Outsider at 10.00 (9/1)
  • 2nd: Outsider at 15.00 (14/1)

Dividend: 10.00 × 15.00 = 150.00 $1 stake returns $150.00. Even at just $0.50, you’d get $75.

Forecast vs Win Bet

Bet Type Odds (Horse A 3.00) Correct Prediction
Win bet Returns 3.00× Just needs to win
Forecast Returns 15.00× Must get 1st AND 2nd right

Forecasts pay roughly 3-10× more than win bets, but are proportionally harder.

When to Use Forecast Bets

Ideal Scenarios

  1. Two clear standouts in a race that should dominate
  2. Maiden races where form is limited but 2 stand out
  3. Class drops where 2 runners are clearly superior
  4. Head-to-heads in small fields
  5. Strong pace scenario where front-runners dominate

When to Avoid

  1. Wide-open races - too many contenders
  2. Small fields (< 4 runners) - dividends too small
  3. No opinion on order - use reverse or consider win bets
  4. Big handicaps - too unpredictable for just 2 picks

Forecast Strategy Tips

1. Consider the Race Pace

Horses that lead early often fill the first two places:

  • Front-runners in small fields
  • Strong pace-setters with stamina

2. Form Study for Forecast

Focus on:

  • Recent finishing positions (2nd places are forecast gold)
  • Course and distance winners
  • Going preference on today’s ground

3. Reverse vs Straight Decision

Confidence Level Bet Type
Very sure of order Straight (1 bet)
Sure of top 2, not order Reverse (2 bets)
50/50 on order Reverse is better value

Forecast vs Tricast

Feature Forecast Tricast
Positions predicted 2 3
Difficulty Medium Very Hard
Typical dividend 10-50× 50-500×
Min runners (usually) 3 8
Combination bets 2 (reverse) 6 (combination)
Best for Short fields Large fields

Computer Straight Forecast (CSF)

In UK racing, the CSF is calculated using a formula that considers:

  • Win odds of both selections
  • Number of runners
  • Odds of all other runners in the field

The CSF often differs from a simple odds multiplication because:

  • Shorter-priced runners produce lower CSF dividends
  • Longer-priced runners produce higher CSF dividends
  • Larger fields increase CSF dividends

Frequently Asked Questions

What’s the minimum number of runners for a forecast?

Most bookmakers require at least 3 runners for forecasts.

Is a reverse forecast better than a straight forecast?

Reverse covers both orders for 2× stake. Use it when unsure of exact order; use straight when confident.

What’s the difference between forecast and exacta?

Same bet - forecast is UK term, exacta is US term. Both predict first two finishers in exact order.

How is the CSF dividend calculated?

Uses a formula considering all runners’ odds, not just your two picks. Often differs from simple odds multiplication.

Can I combine forecasts with other bets?

Some bookmakers allow forecast accumulators across different races.
